Instead, a player will try to castle and seek safety on the edge of the board behind friendly pawns. In the endgame, however, the king emerges to play a role as an offensive piece as well as assisting in the promotion of their remaining pawns. It is not meaningful to assign a value to the relative to the other pieces. Queen chess — The queen is the most powerful piece in the game of chess, able to move any number of squares vertically, horizontally or diagonally. Each player starts the game with one queen, placed in the middle of the first rank next to the king, because of the value of a queen, it is sometimes used as bait to lure an opponent into a trap by a queen sacrifice.
Another tactic is to use the queen to threaten the opponents queen, the queen is often used in conjunction with another piece, such as teamed with a bishop or rook, where the pieces could guard each other while threatening the opponent pieces. With the chessboard oriented correctly, the queen starts on a white square. The white queen starts on d1, while the queen starts on d8.
Because the queen is the strongest piece, a pawn is promoted to a queen in the vast majority of the cases, the modern chess queen gained power in the 15th century in concert with traditions of queenly rule in Europe. Examples of this shift would be the end of chivalry by which Queen Elizabeth I ended the tradition that any knight could create another. The piece is known as the minister.
In Polish it is known as the Hetman — the name of a major historical military-political office, in Russian it is known as ferz. The queen captures by occupying the square on which an enemy piece sits, although both players start with one queen each, a player can promote a pawn to any of several types of pieces, including a queen, when the pawn is moved to the players furthest rank. Such a queen created by promotion can be a queen, or if the players queen has been captured. Pawn promotion to a queen is colloquially called queening, which is by far the most common type of piece a pawn is promoted to because of the power of a queen.
Ordinarily, the queen is stronger than a rook and a bishop together. It is almost always disadvantageous to exchange the queen for a piece other than the enemys queen. The reason that the queen is stronger than a combination of a rook and bishop, second, the queen is not hampered by the bishops inability to control squares of the opposite color to the square on which it stands. A factor in favor of the rook and bishop is that they can attack a square twice, however, experience has shown that this factor is usually less significant than the points favoring the queen.
The queen is strongest when the board is open, when the king is poorly defended. Rook chess — A rook is a piece in the strategy board game of chess. Formerly the piece was called the tower, marquess, rector, the term castle is considered informal, incorrect, or old-fashioned. However, in Persian the word for castling is qaleh raften, each player starts the game with two rooks, one in each of the corner squares on their own side of the board. The white rooks start on squares a1 and h1, while the black rooks start on a8, the rook moves horizontally or vertically, through any number of unoccupied squares.
As with captures by other pieces, the captures by occupying the square on which the enemy piece sits. The rook also participates, with the king, in a move called castling. In the medieval shatranj, the rook symbolized a chariot, Persian war chariots were heavily armoured, carrying a driver and at least one ranged-weapon bearer, such as an archer. The sides of the chariot were built to resemble fortified stone work, giving the impression of small, mobile buildings, however, in the West the rook is almost universally represented as a crenellated turret.
An exception is seen in the British Museums collection of the medieval Lewis chess pieces in which the rooks appear as stern warders or wild-eyed Berzerker warriors, rooks usually are similar in appearance to small castles, and as a result a rook is sometimes called a castle. This usage was common in the past but today it is rarely if ever used in literature or among players. The Russian name for the means a sailing boat or longship of Northern cultures such as the Vikings.
Two rooks are generally considered to be slightly more than a queen. Winning a rook for a bishop or knight is referred to as winning the exchange, rooks and queens are called heavy pieces or major pieces, as opposed to bishops and knights, the minor pieces.
In that position, the support each other, and can more easily move to occupy. A common strategic goal is to place a rook on the first rank of an open file, from this position, the rook is relatively unexposed to risk but can exert control on every square on the file. If one file is particularly important, a player might advance one rook on it, a rook on the seventh rank is typically very powerful, as it threatens the opponents unadvanced pawns and hems in the enemy king.
A rook on the rank is often considered sufficient compensation for a pawn. Glossary of chess — This page explains commonly used terms in chess in alphabetical order. Some of these have their own pages, like fork and pin, absolute pin A pin against the king is called absolute since the pinned piece cannot legally move out of the line of attack. Describes a piece that controls a number of squares, or a piece that has a number of available for its next move.
An active defense is a defense employing threat or counterattack, adjournment Suspension of a chess game with the intention to finish it later. It was once common in high-level competition, often occurring soon after the first time control. Adjudication Decision by a chess player on the outcome of an unfinished game. This practice is now uncommon in over-the-board events, but does happen in online chess when one refuses to continue after an adjournment. Adjust To adjust the position of a piece on its square without being required to move it, a player may only do this on his or her turn to move, and he or she must first say I adjust, or the French equivalent Jadoube.
Advanced pawn A pawn that is on the side of the board.
An advanced pawn may be if it is overextended, lacking support and difficult to defend. An advanced passed pawn that threatens to promote can be especially strong, advantage A better position with the chance of winning the game. Evaluation factors can include space, time, material, and threats, alekhines gun A formation in which a queen backs up two rooks on the same file.
Algebraic notation The standard way to record the moves of a chess game, Amateur The distinction between professional and amateur is not very important in chess as amateurs may win prizes, accept appearance fees, and earn any title, including World Champion. In the 19th century, Amateur was sometimes used in published game scores to conceal the name of the player in a Master vs.
It was thought to be impolite to use a name without permission. See also NN or N. Antipositional A move or a plan that is not in accordance with the principles of positional play, antipositional is used to describe moves that are part of an incorrect plan rather than a mistake made when trying to follow a correct plan.
Antipositional moves are often pawn moves, since pawns cannot move backwards to return to squares they have left, anti-Sicilian An opening variation that White uses against the Sicilian Defense other than the most common plan of 2. Nf3 followed by 3. Bishop chess — A bishop is a piece in the board game of chess. Each player begins the game with two bishops, one starts between the kings knight and the king, the other between the queens knight and the queen.
The starting squares are c1 and f1 for Whites bishops, and c8, the bishop has no restrictions in distance for each move, but is limited to diagonal movement. Bishops, like all other pieces except the knight, cannot jump over other pieces, a bishop captures by occupying the square on which an enemy piece sits.
The bishops may be differentiated according to which wing they begin on, i. As a consequence of its movement, each bishop always remains on either the white or black squares. The bishops predecessor in medieval chess, shatranj, was the alfil, meaning the elephant, as a consequence, each fil was restricted to eight squares, and no fil could attack another. The modern bishop first appeared shortly after in Courier chess, a piece with this move, called a cocatriz or crocodile, is part of the Grande Acedrex in the game book compiled in for King Alfonso X of Castile.
Derivatives of alfil survive in the languages of the two countries where chess was first introduced within Western Europe—Italian and Spanish and it was known as the aufin in French, or the aufin, alphin, or archer in early English. The term bishop first entered the English language in the 16th century, in all other Germanic languages, except for Icelandic, it is called various names, all of which directly translate to English as runner or messenger.
In Romanian, it is known as nebun which refers to a crazy person, in Icelandic, however, it is called biskup, with the same meaning as in English. The canonical chessmen date back to the Staunton chess set of , the pieces deep groove symbolizes a bishops mitre. Some have written that the groove originated from the form of the piece. The British chose to call the piece a bishop because the projections at the top resembled a mitre. This groove was interpreted differently in different countries as the game moved to Europe, in France, for example, the groove was taken to be a jesters cap, hence in France the bishop is called fou.
Domenico Lorenzo Ponziani — Domenico Lorenzo Ponziani was an 18th-century Italian law professor, priest, chess player, composer and theoretician. He is best known today for his chess writing, Ponziani was born in Modena in In he graduated in law at the University of San Carlo and was admitted to the College of Advocates in and he was Professor of Civil Law at the University of Modena from to when he retired taking a pension and the title of honorary professor. In Ponziani took orders as a priest and in he became a canon in the Modena Cathedral and he became Vicar General in , received the title of Protonotary Apostolic, and was made Vicar Capitular in Ponziani died in Modena and is buried in the Modena Cathedral, Ponziani was friends with fellow Modenese chess players and writers Ercole del Rio and Giambattista Lolli, and collectively the trio are known as the Modenese Masters.
In Ponziani published the first edition of Il giuoco incomparabile degli scacchi, as Ponziani did not include his name in the work it was identified to the Anonymous Modenese. The second edition in was much improved and laid out the principles of the Italian school of chess as exemplified by 17th-century Italian masters such as Gioachino Greco, ponzianis work is the best practical guide produced by the Modenese Masters.
Like writings by del Rio and Lolli, Ponziani deals only with the opening and endgame, in the opening, the primary objective is to obtain the maximum amount of mobility for the pieces, aiming in particular for vulnerable points such as the f2 or f7 square. No importance is attached to formation or maintenance of a pawn center—pawns are used to drive back enemy pieces, in the opening, Ponziani is best known as the eponym of the Ponziani Opening, although he did not originate it as it was published by Lucena around His name is attached to the Ponziani Countergambit in the Ponziani Opening as he published the first analysis in Ponzianis manuscript contained the endgame study above, kg5 Or Ke6 or Ke5, but not Kf6.
Ponziani also gave an example of a blockade or fortress. Endgame tablebase — An endgame tablebase is a computerized database that contains precalculated exhaustive analysis of chess endgame positions. It is typically used by a chess engine during play. The tablebase contains the value of each possible move in each possible position. Thus, the acts as an oracle, always providing the optimal moves. Typically the database records each possible position with certain pieces remaining on the board, tablebases are generated by retrograde analysis, working backwards from a checkmated position.
By , all positions with up to six pieces had been solved. By August , tablebases had solved chess for every position with up to seven pieces, the solutions have profoundly advanced the chess communitys understanding of endgame theory. For this reason, they have called into question the 50 move rule since many positions are now seen to exist that are a win for one side. Tablebases have enhanced competitive play and facilitated the composition of endgame studies and they provide a powerful analytical tool.
While endgame tablebases for other games like checkers, chess variants or Nine Mens Morris exist. Physical limitations of computer hardware aside, in principle it is possible to solve any game under the condition that the state is known. Weak solutions exist for more complex games, such as checkers. Other games, such as chess and Go, have not been solved because their game complexity is too vast for computers to all possible positions. To reduce the complexity, researchers have modified these complex games by reducing the size of the board, or the number of pieces.
Computer chess is one of the oldest domains of artificial intelligence, claude Shannon proposed formal criteria for evaluating chess moves in In , Alan Turing designed a chess playing program, which assigned values for material and mobility. However, even as competent chess programs began to develop, they exhibited a glaring weakness in playing the endgame, programmers added specific heuristics for the endgame — for example, the king should move to the center of the board.
Apart from World Champion, Grandmaster is the highest title a chess player can attain, once achieved, the title is held for life. It is often abbreviated to GM, the abbreviation IGM for International Grandmaster is also sometimes used, particularly in older literature. Since about , most of the top 10 women have held the GM title, a separate gender-segregated title, Woman Grandmaster, is also available. The International Correspondence Chess Federation awards the title of International Correspondence Chess Grandmaster, the first known use of the term grandmaster in connection with chess was in an issue of Bells Life, in which a correspondent referred to William Lewis as our past grandmaster.
Lewis himself later referred to Philidor as a grandmaster, and the term was applied to a few other players. In the Ostend tournament of the term grandmaster was used, the tournament was divided into two sections, the Championship Tournament and the Masters Tournament. The Championship section was for players who had won an international tournament.
Siegbert Tarrasch won the Championship section, over Carl Schlechter, Dawid Janowski, Frank Marshall, Amos Burn and these players were described as grandmasters for the purposes of the tournament. Tied for second with 12 points were Aron Nimzowitsch and Rudolf Spielmann, by some accounts, in the St.
Petersburg chess tournament, the title Grandmaster was formally conferred by Russian Tsar Nicholas II, who had partially funded the tournament. This title was abolished in , after having been awarded to Boris Verlinsky, the title was brought back in , and awarded to Mikhail Botvinnik, who thus became the first official Grandmaster of the USSR. John Nunn — John Denis Martin Nunn is an English chess grandmaster, a three-time world champion in chess problem solving, a chess writer and publisher, and a mathematician. He is one of Englands strongest chess players and once was in the top ten.
As a junior, he showed a talent for the game and in , at twelve years of age. At the time, he was Oxfords youngest undergraduate since Cardinal Wolsey in , in , he became the European Junior Champion. He gained the Grandmaster title in and was British champion in , Nunn has twice won individual gold medals at Chess Olympiads. In , he finished sixth in the inaugural World Cup and his best performance in the World Chess Championship cycle came in , when he lost a playoff match against Lajos Portisch for a place in the Candidates Tournament.
He won the prestigious Hoogovens tournament in , and and he achieved his highest Elo rating of in January Six years earlier, in January , his rating of was high enough to elevate him into the worlds top ten. This was close to the peak of the English chess boom, as well as being a strong player, Nunn is regarded as one of the best contemporary authors of chess books. He has penned many books, including Secrets of Grandmaster Chess which won the British Chess Federation Book of the Year award in and he is the director of chess publishers Gambit Publications.
As an annotator he is equally at home presenting lucid prose descriptions for the relative novice and his enormous powers of understanding and his constant thirst for knowledge distracted him from chess. Nunn is also involved with problems, composing several examples. There were further wins of the World Championship in and in and he is the third person ever to gain both over-the-board and solving GM titles.
Since the mids, Nunn has been engaged in mining from chess endgame tablebases. Nunn is thus the foremost data miner of chess endgame tablebases and this work corresponds to the endgame part of the work of Berlekamp, Conway et al.

Best response — In game theory, the best response is the strategy which produces the most favorable outcome for a player, taking other players strategies as given. Reaction correspondences, also known as best response correspondences, are used in the proof of the existence of mixed strategy Nash equilibria, one constructs a correspondence b, for each player from the set of opponent strategy profiles into the set of the players strategies. Response correspondences for all 2x2 normal form games can be drawn with a line for each player in a unit square strategy space, figures 1 to 3 graphs the best response correspondences for the stag hunt game.
The dotted line in Figure 1 shows the probability that player Y plays Stag. In Figure 2 the dotted line shows the probability that player X plays Stag. There are three distinctive reaction correspondence shapes, one for each of the three types of symmetric 2x2 games, coordination games, discoordination games and games with dominated strategies, any payoff symmetric 2x2 game will take one of these three forms.
Games in which players score highest when both players choose the strategy, such as the stag hunt and battle of the sexes are called coordination games. Games such as the game of chicken and hawk-dove game in which players score highest when they choose opposite strategies, the third Nash equilibrium is a mixed strategy which lies along the diagonal from the bottom left to top right corners. If the players do not know one of them is which, then the mixed Nash is an evolutionarily stable strategy. Otherwise an uncorrelated asymmetry is said to exist, and the corner Nash equilibria are ESSes, Games with dominated strategies have reaction correspondences which only cross at one point, which will be in either the bottom left, or top right corner in payoff symmetric 2x2 games.
For instance, in the prisoners dilemma, the Cooperate move is not optimal for any probability of opponent Cooperation. Figure 5 shows the correspondence for such a game, where the dimensions are Probability play Cooperate. A wider range of reaction correspondences shapes is possible in 2x2 games with payoff asymmetries, for each player there are five possible best response shapes, shown in Figure 6.
From left to right these are, dominated strategy, dominated strategy, rising, falling, while there are only four possible types of payoff symmetric 2x2 games, the five different best response curves per player allow for a larger number of payoff asymmetric game types. Many of these are not truly different from each other, the dimensions may be redefined to produce symmetrical games which are logically identical. One well-known game with payoff asymmetries is the matching pennies game, player Ys reaction correspondence is that of a coordination game, while that of player X is a discoordination game.
The only Nash equilibrium is the combination of mixed strategies where both players independently choose heads and tails with probability 0. Draw chess — In chess, a draw is the result of a game ending in a tie.

Usually, in tournaments a draw is worth a point to each player, while a win is worth one point to the victor. For the most part, a draw occurs when it appears that neither side will win, draws are codified by various rules of chess including stalemate, threefold repetition, and the fifty-move rule. A draw also occurs when player has sufficient material to checkmate the opponent or when no sequence of legal moves can lead to checkmate. Unless specific tournament rules forbid it, players may agree to a draw at any time, ethical considerations may make a draw uncustomary in situations where at least one player has a reasonable chance of winning.
For example, a draw could be called after a move or two, but this would likely be thought unsporting, until , tournament games that were drawn were replayed. The Paris tournament of had so many games to be replayed that it caused organisational problems. In the British Chess Association decided to each player half a point instead of replaying the game. In games played under time control, a draw may result under additional conditions, a stalemate is an automatic draw, as is a draw because of insufficient material to checkmate.
A draw by repetition or the fifty-move rule may be claimed by one of the players with the arbiter. A claim of a draw first counts as an offer of a draw, once a claim or draw offer has been made, it cannot be withdrawn. If the claim is verified or the offer accepted, the game is over. Otherwise, the offer or claim is nullified and the game continues, an offer of a draw should be made after a player makes a move but before he presses his game clock.
The other player also declines the offer if he makes a move, the offer of a draw should be recorded by each player in their scoresheet using the symbol as per Appendix C. Article 5 of the FIDE Laws of Chess gives the ways a game may end in a draw, Stalemate — if the player on turn has no legal move but is not in check, this is stalemate and the game is automatically a draw. In such a case the draw is not automatic - a player must claim it if he wants the draw. When the position will occur for the time after the players intended next move, he writes the move on his scoresheet but does not make the move on the board.
If the claim is not made on the move in which the repetition occurs, of course, the opportunity may present itself again. Algebraic notation chess — Algebraic notation is a method for recording and describing the moves in a game of chess. It is based on a system of coordinates to identify each square on the chessboard. It is now standard among all chess organizations and most books, magazines, in English-speaking countries, the parallel method of descriptive notation was generally used in chess publications until about A few older players still use descriptive notation but it is no longer recognised by FIDE, Algebraic notation exists in various forms and languages and is based on a system developed by Philipp Stamma.
Stamma used the names of the squares, but he used p for pawn moves. This article describes standard algebraic notation required by FIDE, each square of the chessboard is identified by a unique coordinate pair—a letter and a number. The vertical columns of squares from Whites left to right are labeled a through h, the horizontal rows of squares are numbered 1 to 8, starting from Whites side of the board. Thus each square has an identification of file letter followed by rank number. Each piece type is identified by an uppercase letter, English-speaking players use the letters K for king, Q for queen, R for rook, B for bishop, and N for knight.
S was also used for the knight in the days of algebraic notation and is still used in chess problems. Players who speak other languages may employ different letters, for example and this style known as figurine algebraic notation. Pawns are not identified by letters, but rather by the absence of one.
Distinguishing between pawns is not necessary for recording moves, since only one pawn can move to a given square, each move of a piece is indicated by the pieces uppercase letter, plus the coordinate of the destination square. When a piece makes a capture, an x is inserted immediately before the destination square, when a pawn makes a capture, the file from which the pawn departed is used to identify the pawn. A colon is used instead of x, either in the same place the x would go or at the end.
En passant captures are indicated by specifying the capturing pawns file of departure, the x, the square. Some texts, such as the Encyclopaedia of Chess Openings, omit indication that any capture has been made, when it is unambiguous to do so, a pawn capture is sometimes described by specifying only the files involved. These shortened forms are called minimal or abbreviated algebraic notation. Knight chess — The knight is a piece in the game of chess, representing a knight.
It is normally represented by a head and neck. Each player starts with two knights, which begin on the row closest to the player, between the rooks and bishops, the knight move is unusual among chess pieces.

When it moves, it can move to a square that is two squares away horizontally and one square vertically, or two vertically and one square horizontally. The complete move therefore looks like the letter L, unlike all other standard chess pieces, the knight can jump over all other pieces to its destination square. It captures a piece by replacing it on its square. The knights ability to jump over other means it tends to be at its most powerful in closed positions. The move is one of the moves in chess, having remained unchanged since before the 7th century.
Because of this it appears in most chess-related regional games. The knight moves alternately to light and dark squares, a knight should always be close to where the action is, meaning it is best used on areas of the board where the opponents pieces are clustered or close together. Pieces are generally more powerful if placed near the center of the board, a knight on the edge of the board attacks only three or four squares and a knight in the corner only two. Moreover, it takes more moves for a knight to switch operation to the opposite side of the board than an uncentralized bishop, rook.
The mnemonic phrases A knight on the rim is grim or A knight on the rim is dim are often used in chess instruction to reflect this principle, the knight is the only piece that can move at the beginning of the game without first moving a pawn. For the reasons above, the best square for the move of each knight is usually one towards the center.
Knights are usually brought into play slightly sooner than the bishops and much sooner than the rooks, because of its move pattern, the knight is especially well-suited for executing a fork. In the numbered diagram, the numbers represent how many moves it takes for a knight to reach each square on the chessboard from its location on the f5-square, a knight is approximately equal in strength and value to a bishop. The bishop has longer range, but is restricted to half the squares on the board. Since the knight can jump over pieces which obstruct other pieces, a knight is best when it has a support point or outpost — a relatively sheltered square where it can be positioned to exert its strength remotely.
Chessboard — A chessboard is the type of checkerboard used in the classic board game chess, and consists of 64 squares and 32 pieces. The squares are arranged in two alternating colors, wooden boards may use naturally light and dark brown woods, while plastic and vinyl boards often use brown or green for the dark squares and shades such as buff or cream for the light squares. Materials vary widely, while wooden boards are used in high-level games, vinyl, plastic. Decorative glass and marble boards are available but rarely accepted for games rated by national or international chess federations, each square on the board has a name from a1 to h8.
According to FIDE equipment standards, the side of a square should be twice the diameter of a pawns base and this is called descriptive chess notation and is no longer commonly used. Bishop and knight checkmate — The bishop and knight checkmate in chess is the checkmate of a lone king which can be forced by a bishop, knight, and king.
With the stronger side to move and with perfect play, checkmate can be forced in at most thirty-three moves from any starting position where the defender cannot quickly win one of the pieces and these exceptions constitute about 0. His second triangle or middle triangle occurs also in the analysis of play with the king in the corner of opposite colour to the shown in Fine. Checkmate can be forced without using either method to complete the mate, opinions differ among chess authors as to whether or not a player should learn this checkmate procedure. James Howell omits the checkmate with two bishops in his book because it occurs but includes the bishop and knight checkmate.
Howell says that he has had it three times and that it more often than the checkmate with two bishops. Silman says, mastering it would take a significant chunk of time, should the chess hopeful really spend many of his precious hours hes put aside for chess study learning an endgame he will achieve only once or twice in his lifetime. International Master Jonathan Hawkins has encountered the only once in games. Grandmaster Andy Soltis says that he has never played this endgame, however, learning it teaches techniques that can be applied elsewhere.
Shaked knew the correct mating pattern, and his victory catapulted him to becoming World Junior Champion and it is assumed in this section that White has the bishop and knight. Thus there are three phases in the process, Driving the opposing king to the edge of the board. Forcing the king out of the corner to the right corner.
Positions which are stalemate, or in which White cannot prevent stalemate or the loss of one of his pieces, such as G and H. These form a significant minority, in almost all of which Black to play can take a piece or irrecoverably fork the pieces or White to play has his pieces irrecoverably forked.
All other positions can be won by White, positions in which White can force mate on a square adjacent to the wrong corner such as I after 1. Positions in which White can prevent the black king reaching the longest diagonal of the colour opposite to that of the bishop, positions which are not closed, such as K - M in the sequel. Open and closed positions are considered separately in the following, if Black opts not to step into a closed position, phase 1 will necessarily drive him to a wrong colour corner, when phase 2 will be necessary.
Two knights endgame — The two knights endgame is a chess endgame with a king and two knights versus a king, possibly with some other material. The material with the king is usually one pawn. In contrast to a plus two bishops, or a bishop and a knight, a king and two knights cannot force checkmate against a lone king. Although there are checkmate positions, the side cannot force them against proper defense. On the other hand, if the side also has material. The winning chances with two knights are insignificant except against a few pawns and these positions were studied extensively by A.
With a single pawn the technique is to block the pawn with one knight and use the king, then when the block on the pawn is removed, the knight can be used to checkmate. Although there are checkmate positions with two knights against a king, they cannot be forced, edmar Mednis stated that this inability to force checkmate is one of the great injustices of chess.
Unlike some other theoretically drawn endgames, such as a rook and bishop versus rook, the player simply has to avoid moving into a position in which he or she can be checkmated on the next move, and always has another move available in such situations. Three knights and a king can force checkmate against a lone king within twenty moves, the player with the lone king has to make a blunder to be checkmated. Nf7 is checkmate, but if Black moves 4, kf8 then White has made no progress.
Johann Berger gave this position, a draw with either side to move, kf6 Ke8 and White has made no progress. There are also checkmate positions with the inferior sides king on the edge of the board, in the position at right, White can try 1. Black can easily avoid this with, for example,1 and this possible checkmate is the basis of some problems.
In this position from a game between Pal Benko and David Bronstein, Black had just underpromoted to a knight, Black did not promote to a queen or any other piece because White could fork Blacks king and his newly promoted piece immediately after the promotion. Nxh2 and a draw was agreed, another example is the eighth game from the World Chess Championship match between Anatoly Karpov and Viktor Korchnoi.
Stalemate — Stalemate is a situation in the game of chess where the player whose turn it is to move is not in check but has no legal move. The rules of chess provide that when stalemate occurs, the ends as a draw. During the endgame, stalemate is a resource that can enable the player with the position to draw the game rather than lose. In more complex positions, stalemate is much rarer, usually taking the form of a swindle that succeeds only if the side is inattentive. Stalemate is also a theme in endgame studies and other chess problems.
The outcome of a stalemate was standardized as a draw in the 19th century, some regional chess variants have not allowed a player to play a stalemating move. In losing chess, another variant, is typically treated as a win for the stalemated player. In popular usage, the word refers to a conflict that has reached an impasse.
With Black to move, Black is stalemated in diagrams 1 to 5, Stalemate is an important factor in the endgame — the endgame set-up in diagram 1, for example, quite frequently is relevant in play. The position in diagram 4 is an example of a pawn drawing against a queen, stalemates of this sort can often save a player from losing an apparently hopeless position. In that position, even if it were Whites move, there is no way to avoid this stalemate without allowing Blacks pawn to promote.
In diagram 5, Black had forced the position to become stalemate, as the previous section suggests, stalemate is a typical element of the endgame, often enabling the player with the inferior position to draw the game. Concerning chess, below are examples of this from actual play. In this game between Viswanathan Anand and Vladimir Kramnik from the World Chess Championship, Black must capture the pawn on f5, an intentional stalemate occurred on the th move of the fifth game of the World Championship match between Viktor Korchnoi and Anatoly Karpov.
The game had been a draw for many moves. However the players were not on speaking terms so neither would offer a draw by agreement, Korchnoi said that it gave him pleasure to stalemate Karpov and that it was slightly humiliating. Sometimes a surprise stalemate saves a game, in the game between Ossip Bernstein and Vasily Smyslov, Black should win by sacrificing the f-pawn and using the king to support the b-pawn.
Perpetual check — In the game of chess, perpetual check is a situation in which one player can force a draw by an unending series of checks. Such a situation arises when the player who is checking cannot deliver checkmate. A draw by perpetual check is no one of the rules of chess. However, such a situation will result in a draw by either threefold repetition or the fifty-move rule.
Perpetual check can also occur in other variants, although the rules relating to it may be different. For example, giving perpetual check is not allowed in both shogi and xiangqi, in this diagram, Black is ahead a rook, a bishop, and a pawn, which would normally be a decisive material advantage. But White, to move, can draw by perpetual check,1, the same position will soon repeat for the third time and White can claim a draw by threefold repetition, or the players will agree to a draw.
In the second diagram, from Unzicker versus Averbakh, Stockholm Interzonal and he can, however, exploit the weakness of Whites kingside pawn structure with 1. The earliest example of perpetual check contained in it is a game played by two players in , N. A draw by perpetual check used to be in the rules of chess, howard Staunton gave it as one of six ways to draw a game in The Chess-Players Handbook.
It has since been removed because perpetual check will eventually allow a claim by either threefold repetition or the fifty-move rule. If a player demonstrates intent to perform perpetual check, the players agree to a draw. Bohn Diagram demonstrating a perpetual check. Fork chess — In chess, a fork is a tactic whereby a single piece makes two or more direct attacks simultaneously. Most commonly two pieces are threatened, which is sometimes called a double attack. The attacker usually aims to gain material by capturing one of the opponents pieces, the defender often finds it difficult to counter two or more threats in a single move.
The attacking piece is called the piece, the pieces attacked are said to be forked. A piece that is defended can still said to be forked if the piece has a lower value. Besides attacking pieces, a target of a fork can be a direct mating threat, or a target can be an implied threat. In December, Fischer won his seventh U. Piatigorsky, accepting an invitation to the very strong second Piatigorsky Cup tournament in Santa Monica. Fischer won the U. Fischer's win in the —67 U. Championship qualified him for the next World Championship cycle.
His observance of the Worldwide Church of God's seventh-day Sabbath was honored by the organizers, but deprived Fischer of several rest days, which led to a scheduling dispute,  causing Fischer to forfeit two games in protest and later withdraw, eliminating himself from the World Championship cycle.
No one in Tunisian chess had previous experience running an event of this stature. Since Fischer had completed less than half of his scheduled games, all of his results were annulled, meaning players who had played Fischer had those games cancelled, and the scores nullified from the official tournament record. In , Fischer began a new effort to become World Champion. His dramatic march toward the title made him a household name and made chess front-page news for a time. He won the title in , but forfeited it three years later. Championship was also a zonal qualifier, with the top three finishers advancing to the Interzonal.
Fischer, however, had sat out the U. Championship because of disagreements about the tournament's format and prize fund. Benko, one of the three qualifiers, agreed to give up his spot in the Interzonal in order to give Fischer another shot at the World Championship. It was a matter of honor". In and , Fischer "dominated his contemporaries to an extent never seen before or since". There was much surprise when Fischer decided to participate: Fischer had not played competitive chess for eighteen months, and many thought he would never return.
Then, to general surprise and delight, he agreed to participate in the Soviet Union vs. With Evans as his second,  Fischer flew to Belgrade  with the intention of playing board one for the rest of the world. Bobby Fischer was the high scorer for his team, with a 3—1 score against Petrosian two wins and two draws ". Petrosian was almost unrecognizable in the first two games, and by the time he had collected himself, although pressing his opponent, he could do no more than draw the last two games of the four-game set".
I do not agree with this In order to rightly be declared a genius in chess, you have to defeat equal opponents by a big margin. As yet he has not done this". In the Candidates matches, Fischer was set to play against Soviet grandmaster and concert pianist  Mark Taimanov in the quarter-finals. He was not alone; the noncommunist press was of the same mind. Only Taimanov insisted that he could win, dismissing Fischer as a mere computer".
He was backed by the firm guidance of Botvinnik, who "had thoroughly analysed Fischer's record and put together a 'dossier' on him", from when he was in talks to play Fischer in a match "a couple of years earlier". N1c3, to which Fischer replied "that the idea was not his—he had come across it in the monograph by the Soviet master Alexander Nikitin in a footnote".
Taimanov came to Vancouver with two seconds, both grandmasters. He thought that the sight of Taimanov and his seconds was the funniest thing he had ever seen. There Taimanov and his seconds would sit, six hands flying, pocket sets waving in the air, while variations were being spouted all over the place. And there sat Taimanov with a confused look on his face. Just before resuming play [in the fifth game] the seconds were giving Taimanov some last-minute advice.
When poor Taimanov entered the playing room and sat down to confront Fischer, his head was so full of conflicting continuations that he became rattled, left a Rook en prise and immediately resigned. Fischer beat Taimanov by the score of 6—0. A typical result between well-matched players might be, say, six wins to four, with nine draws". One's moves may be so powerful that the other may not be able to stop him, but the plan behind the moves will be clear. Not so with Fischer. His moves did not make sense Upon losing the final game of the match, Taimanov shrugged his shoulders, saying sadly to Fischer: He was banned from writing articles, was deprived of his monthly stipend Fischer was next scheduled to play against Danish grandmaster Bent Larsen.
It is hard to say how their match will end, but it is clear that such an easy victory as in Vancouver [against Taimanov] will not be given to Fischer. I think Larsen has unpleasant surprises in store for [Fischer], all the more since having dealt with Taimanov thus, Fischer will want to do just the same to Larsen and this is impossible.
Fischer beat Larsen by the score of 6—0. But now I am at a loss for anything whatever to say So, it is out of the question for me to explain how Bobby, how anyone, could win six games in a row from such a genius of the game as Bent Larsen". Garry Kasparov later wrote that no player had ever shown a superiority over his rivals comparable to Fischer's "incredible" 12—0 score in the two matches. Despite Fischer's results against Taimanov and Larsen, his upcoming match against Petrosian seemed a daunting task. He is a great chess player but no genius". Fischer's recent record raises the distinct possibility that he has made a breakthrough in modern chess theory.
His response to Petrosian's elaborately plotted 11th move in the first game is an example: Russian experts had worked on the variation for weeks, yet when it was thrown at Fischer suddenly, he faced its consequences alone and won by applying simple, classic principles. Upon completion of the match, Petrosian remarked: I on the other hand, either had a breakdown or was tired, or something else happened, but the last three games were no longer chess. Since the time that he has been playing them, miracles have begun.
Fischer gained a far higher rating than any player in history up to that time. Fischer's career-long stubbornness about match and tournament conditions was again seen in the run-up to his match with Spassky. Before and during the match, Fischer paid special attention to his physical training and fitness, which was a relatively novel approach for top chess players at that time. He had also arranged for exclusive use of his hotel's swimming pool during specified hours, and swam for extended periods, usually late at night.
The Cold War trappings made the match a media sensation. Kasparov remarked, "Fischer fits ideologically into the context of the Cold War era: It was as if an Eskimo had cleared a tennis court in the snow and gone on to win the world championship". Fischer also made an appearance on a Bob Hope TV special. Chess Federation doubled in ,  and peaked in ; in American chess, these years are commonly referred to as the "Fischer Boom".
Fischer won the ' Chess Oscar '  an award, started in , given to the best chess player, determined through votes from chess media and leading players for , , and Fischer was scheduled to defend his title in against Anatoly Karpov , who emerged as his challenger. He made three principal non-negotiable demands:. The delegates voted in favor of Fischer's win proposal, but rejected his other two proposals, and limited the number of games in the match to Cramer informs me that the rules of the winner being the first player to win ten games, draws not counting, unlimited number of games and if nine wins to nine match is drawn with champion regaining title and prize fund split equally were rejected by the FIDE delegates.
The delegates responded by reaffirming their prior decisions, but did not accept Fischer's resignation and requested that he reconsider. Due to the continued efforts of U. Chess Federation officials,  a special FIDE Congress was held in March in Bergen,  Netherlands in which it was accepted that the match should be of unlimited duration, but the 9—9 clause was once again rejected, by a narrow margin of 35 votes to No reply was received from Fischer by April 3.
Thus, by default, Karpov officially became World Champion. Karpov met with Fischer several times after , in friendly but ultimately unsuccessful attempts to arrange a match since Karpov would never agree to play to Brian Carney opined in The Wall Street Journal that Fischer's victory over Spassky in left him nothing to prove, except that perhaps someone could someday beat him, and he was not interested in the risk of losing.
And that Fischer's refusal to recognize peers also allowed his paranoia to flower: He descended into what can only be considered a kind of madness". Bronstein felt that Fischer "had the right to play the match with Karpov on his own conditions". Was Fischer right in demanding that the world title be protected by a two point handicap — that the challenger would be considered the winner with a 10—8 score and that the champion would retain his title in the event of a 9—9 draw?
Yes, this was quite natural: Soviet grandmaster Lev Alburt felt that the decision to not concede to Fischer's demands rested on Karpov's "sober view of what he was capable of". After the World Chess Championship, Fischer did not play a competitive game in public for nearly 20 years. On May 26, , while walking in Pasadena, Fischer was arrested by a police patrolman, allegedly because Fischer matched the description of a man who had just committed a bank robbery in the area. In , Fischer stayed at the home of grandmaster Peter Biyiasas , where, over a period of four months, he beat Biyiasas seventeen times in a series of speed games.
He was too good. There was no use in playing him. I was getting beaten, and it wasn't clear to me why. It wasn't like I made this mistake or that mistake. It was like I was being gradually outplayed, from the start. He wasn't taking any time to think. The most depressing thing about it is that I wasn't even getting out of the middle game to an endgame. I don't ever remember an endgame. He honestly believes there is no one for him to play, no one worthy of him. I played him, and I can attest to that. Fischer emerged after twenty years of isolation to play Spassky then tied for 96th—nd on the FIDE rating list in a "Revenge Match of the 20th century" in This match took place in Sveti Stefan and Belgrade , Yugoslavia , in spite of a United Nations embargo that included sanctions on commercial activities.
Fischer insisted he was still the true World Champion, and that for all the games in the FIDE-sanctioned World Championship matches, involving Karpov, Korchnoi, and Kasparov, the outcomes had been prearranged. According to grandmaster Andrew Soltis: Yet the games also reminded many fans of how out of place Fischer was in He was still playing the openings of a previous generation.
He was, moreover, the only strong player in the world who didn't trust computers and wasn't surrounded by seconds and supplicants. Fischer won the match with 10 wins, 5 losses, and 15 draws. Maybe his strength is or It wouldn't be close between us". Fischer and Spassky gave ten press conferences during the match. Bobby is the most misunderstood, misquoted celebrity walking the face of the earth.
Department of the Treasury warned Fischer before the start of the match that his participation was illegal, that it would violate President George H. Fischer claimed that standard chess was stale and that he now played blitz games of chess variants , such as Chess From to , Fischer lived in Baguio City in the Philippines,  residing in the same compound as the Filipino grandmaster Eugenio Torre , a close friend who acted as his second during his match with Spassky. Fischer made numerous anti-Jewish statements and professed a general hatred for Jews since at least the early s.
He also championed a brand of anti-semitism that could only be thought up by a mind completely cut off from reality". Although Fischer described his mother as Jewish in a interview,  he later denied his Jewish ancestry. From the s on, Fischer's comments about Jews were a major theme in his public and private remarks. He participated in at least 34 such broadcasts, mostly with radio stations in the Philippines, but also in Hungary, Iceland, Colombia, and Russia. In , he gave a radio call-in interview to a station in Budapest, Hungary, during which he described himself as the "victim of an international Jewish conspiracy ".
In another radio interview, Fischer said that it became clear to him in , after reading The Secret World Government by Count Cherep-Spiridovich , that Jewish agencies were targeting him. Just kill the Motherfuckers! Shortly after midnight on September 12, , Philippines local time approximately four hours after the September 11, attacks in the U.

Bush, asking "For mercy, charity", and, if that was not possible, "to put [him] in the same cell with Bobby Fischer" and "to give [them] a chess set".
Secretary of State Colin Powell to help him do so, though to no effect. Seeking ways to evade deportation to the United States, Fischer wrote a letter to the government of Iceland in early January , requesting Icelandic citizenship. When this proved insufficient for the Japanese authorities, Althing the Icelandic Parliament , at the behest of William Lombardy,   agreed unanimously to grant Fischer full citizenship in late March for humanitarian reasons, as they felt he was being unjustly treated by the U.
On December 10, , Fischer telephoned an Icelandic television station and pointed out a winning combination , missed by the players and commentators. Fischer claimed, in , that those belongings were worth millions of U. He became more erratic in his years after losing his World Championship title. Although Fischer's mother was Jewish, Fischer disavowed having Jewish roots. Fischer joined the Worldwide Church of God in the mids.
The church prescribed Saturday Sabbath , and forbade work and competitive chess on Sabbath. Armstrong went unfulfilled,  and the church was rocked by revelations of a series of sex scandals involving Garner Ted Armstrong. It quickly became the object of a legal battle involving claims from four parties, with Miyoko Watai ultimately inheriting what remained of Fischer's estate after government claims.
According to a press release issued by Samuel Estimo, an attorney representing Jinky Young, the Supreme Court of Iceland ruled, in December , that Watai's claim of marriage to Fischer was invalidated because of her failure to present the original copy of their alleged marriage certificate. A DNA sample was taken and Fischer's body was then reburied. Valery Krylov, advisor to Anatoly Karpov and a specialist in the "psycho-physiological rehabilitation of sportsmen", believed Bobby suffered from schizophrenia.
The evidence is stronger for paranoid personality disorder. For most of his career, Fischer was predictable in his use of openings and variations of those openings. Despite this seeming disadvantage, it was very difficult for opponents to exploit this limitation, because Fischer's knowledge of the openings and variations that he used was extensive. As Black, Fischer would usually play the Najdorf Sicilian against 1.
Fischer was a master of playing with,  and against,  the Sicilian Defense. The next most common defense against Fischer's 1. But I doubt it! The defense is anti-positional and weakens the K-side. Fischer was renowned for his opening preparation and made numerous contributions to chess opening theory.
Fischer was a recognized expert in the black side of the Najdorf Sicilian and the King's Indian Defense. Ne2 Ba6 was named after him. Fischer established the viability of the so-called Poisoned Pawn Variation of the Najdorf Sicilian 1. This bold queen sortie, to snatch a pawn at the expense of development, had been considered dubious,    but Fischer succeeded in proving its soundness.
On the white side of the Sicilian , Fischer made advances to the theory of the line beginning 1. Nc3 a6 or e6 6. Bc4,   which has sometimes been named after him. It loses by force. Nf3 d6,  which has since become known as the Fischer Defense , as a refutation to the King's Gambit. Fischer had excellent endgame technique. In , Fischer filed for U. Patent 4,, for a new type of chess clock , which gave each player a fixed period at the start of the game and then added a small increment after each completed move. Fischer heavily disparaged chess as it was currently being played at the highest levels.
The goal of Fischerandom Chess was to ensure that a game between two players is a contest between their understandings of chess, rather than their abilities to memorize opening lines or prepare opening strategies. In a Icelandic Radio interview, Fischer explained his reasons for advocating Fischerandom Chess: In chess so much depends on opening theory, so the champions before the last century did not know as much as I do and other players do about opening theory. You cannot compare the playing strength, you can only talk about natural ability. Memorisation is enormously powerful. Some kid of fourteen today, or even younger, could get an opening advantage against Capablanca, and especially against the players of the previous century, like Morphy and Steinitz.
Maybe they would still be able to outplay the young kid of today. Or maybe not, because nowadays when you get the opening advantage not only do you get the opening advantage, you know how to play, they have so many examples of what to do from this position It is all just memorization and prearrangement Kasparov calls Fischer "perhaps the most mythologically shrouded figure in chess".
Some grandmasters compared Fischer's play to that of a computer;   a player without noticeable weaknesses. Although international ratings were just introduced in , Chessmetrics a website that uses algorithms to rank performances retrospectively and uniformly throughout chess history determined that Fischer's peak rating was in October —the highest in history. His one-year peak average was , the highest of all time. His three-year peak average was , from January to December —the second highest ever, just behind Garry Kasparov.
Fischer was ranked as the number one player in the world for a total of different months, running not consecutively from February until July Fischer's great rival Mikhail Tal praised him as "the greatest genius to have descended from the chess heavens". Biographers David Edmonds and John Eidinow wrote: Faced with Fischer's extraordinary coolness, his opponents [sic] assurance would begin to disintegrate.
A Fischer move, which at first glances looked weak, would be reassessed. It must have a deep master plan behind it, undetectable by mere mortals more often than not they were right, it did. Grandmasters would wilt, their suits would crumple, sweat would glisten on their brows, panic would overwhelm their nervous systems. Errors would creep in. Calculations would go awry. There was talk among grandmasters that Fischer hypnotized his opponents, that he undermined their intellectual powers with a dark, mystic, insidious force.
Kasparov wrote that Fischer "became the detonator of an avalanche of new chess ideas, a revolutionary whose revolution is still in progress". He didn't divide the East and the West, he brought them together in their admiration of him. Fischer, who had taken the highest crown almost singlehandedly from the mighty, almost invincible Soviet chess empire, shook the whole world, not only the chess world, to its core. He started a chess boom not only in the United States and in the Western hemisphere, but worldwide.
Teaching chess or playing chess as a career had truly become a respectable profession. After Bobby, the game was simply not the same. Fischer was a charter inductee into the U. Chess Hall of Fame in Washington, D. After routing Taimanov, Larsen, and Petrosian in , Fischer achieved a then-record Elo rating of By the fifth day of the championship, all 24 participants became ineligible for the prize, having drawn or lost at least one game.

Over two matches, Korchnoi was required to beat Karpov by at least 6—5 and 6—5: This scenario nearly materialized since the match was tied 5—5 after 31 games before Karpov won the 32nd game.
Korchnoi could, in theory, have won 6—0 in the first match and lost 5—6 in the second, with an aggregate win total of 11 games to Karpov's 6. Recognizing this, FIDE president Euwe proposed that the champion should only have a rematch in the event he lost 5—6, but Karpov rejected this proposal. Not counting draws would be "an accurate test of who is the world's best player". Champion Arnold Denker , who was in contact with Fischer during the negotiations with FIDE, claimed that Fischer wanted a long match to be able to play himself into shape after a three-year layoff.
