In chess, a king walk, also known as a king march, steel king, or wandering king (Dutch : wandelkoning, literally "wanderking"), is a maneuver where the king travels a large distance to a different part of the board in the middlegame or opening. During a king walk, the king may travel along its own side of the board (from kingside to queenside , or vice versa) to reach a safer position. Alternatively, it may travel up the board, often involved in a mating attack against the opposing king. [2]
Activating the king before the endgame is a highly unusual occurrence; before the endgame, the safety of the king is considered paramount, and players are recommended to keep it out of harm's way. [3] [4] In contrast, Wilhelm Steinitz, often known as the father of modern chess, was renowned for his maxim that "the king is a fighting piece". [5] [6] Dutch chess historian and author Tim Krabbé has documented over one hundred such games. [2]
Because of the rarity of such tactics, those that reap rewards for the attacking player often have brilliancy prizes bestowed upon them. [7] [8] Perhaps the most famous in recent history, [9] where Nigel Short defeated Jan Timman in Tilburg in 1991, was voted as one of the hundred greatest chess games in a list compiled by master Graham Burgess, and grandmasters John Nunn and John Emms.

Aron Nimzowitsch was a Latvian-born, Latvian-Danish chess player and writer. In the late 1920s, Nimzowitsch was one of the best chess players in the world. He was the foremost figure amongst the hypermoderns and wrote a very influential book on chess theory: My System (1925–1927). Nimzowitsch's seminal work Chess Praxis, originally published in German in 1929, was purchased by a pre-teen and future World Champion Tigran Petrosian and was to have a great influence on his development as a chess player.
Machgielis "Max" Euwe was a Dutch chess player, mathematician, author, and chess administrator. He was the fifth player to become World Chess Champion, a title he held from 1935 until 1937. He served as President of FIDE, the World Chess Federation, from 1970 to 1978.
In chess and other similar games, the endgame is the stage of the game when few pieces are left on the board.
The Game of the Century is a chess game that was won by the 13-year-old future world champion Bobby Fischer against Donald Byrne in the Rosenwald Memorial Tournament at the Marshall Chess Club in New York City on October 17, 1956. In Chess Review, Hans Kmoch dubbed it "The Game of the Century" and wrote: "The following game, a stunning masterpiece of combination play performed by a boy of 13 against a formidable opponent, matches the finest on record in the history of chess prodigies."
The fifty-move rule in chess states that a player can claim a draw if no capture has been made and no pawn has been moved in the last fifty moves. The purpose of this rule is to prevent a player with no chance of winning from obstinately continuing to play indefinitely or seeking to win by tiring the opponent.
The Ruy Lopez, also called the Spanish Opening or Spanish Game, is a chess opening characterised by the moves:
Checkmate is any game position in chess and other chess-like games in which a player's king is in check and there is no possible escape. Checkmating the opponent wins the game.

Géza Maróczy was a Hungarian chess player, one of the leading players in the world in his time. He was one of the inaugural recipients of the title International Grandmaster from FIDE in 1950.

Robert Hübner is a German chess grandmaster, chess writer, and papyrologist. He was one of the world's leading players in the 1970s and early 1980s.
The Tarrasch rule is a general principle that applies in the majority of chess middlegames and endgames. Siegbert Tarrasch (1862–1934) stated the "rule" that rooks should be placed behind passed pawns – either the player's or the opponent's. The idea behind the guideline is that (1) if a player's rook is behind his passed pawn, the rook protects it as it advances, and (2) if it is behind an opponent's passed pawn, the pawn cannot advance unless it is protected along its way.
In chess, the exchange is a situation in which one player exchanges a minor piece for a rook. The side which wins the rook is said to have won the exchange, while the other player has lost the exchange, since the rook is usually more valuable. Alternatively, the side having a rook for a minor piece is said to be up the exchange, and the other player is down the exchange. The opposing captures often happen on consecutive moves, although this is not strictly necessary. It is generally detrimental to lose the exchange, although occasionally one may find reason to purposely do so; the result is an exchange sacrifice. The minor exchange is an uncommon term for the exchange of a bishop and knight.
In chess, a swindle is a ruse by which a player in a losing position tricks their opponent and thereby achieve a win or draw instead of the expected loss. It may also refer more generally to obtaining a win or draw from a clearly losing position. I. A. Horowitz and Fred Reinfeld distinguish among "traps", "pitfalls", and "swindles". In their terminology, a "trap" refers to a situation where players go wrong through their own efforts. In a "pitfall", the beneficiary of the pitfall plays an active role, creating a situation where a plausible move by the opponent will turn out badly. A "swindle" is a pitfall adopted by a player who has a clearly lost game. Horowitz and Reinfeld observe that swindles, "though ignored in virtually all chess books", "play an enormously important role in over-the-board chess, and decide the fate of countless games".
The opposite-colored bishops endgame is a chess endgame in which each side has a single bishop and the bishops reside on opposite-colored squares. Without other pieces besides pawns, these endings are widely known for their tendency to result in a draw. These are the most difficult endings in which to convert a small material advantage to a win. With additional pieces, the stronger side has more chances to win, but not as many as when bishops are on the same color.
The rook and bishop versus rook endgame is a chess endgame where one player has just a king, a rook, and a bishop, and the other player has just a king and a rook. This combination of material is one of the most common pawnless chess endgames. It is generally a theoretical draw, but the rook and bishop have good winning chances in practice because the defense is difficult. Ulf Andersson won the position twice within a year, once against a grandmaster and once against a candidate master; and grandmaster Keith Arkell has won it 18 times out of 18. In positions that have a forced win, up to 59 moves are required. Tony Kosten has seen the endgame many times in master games, with the stronger side almost always winning. Pal Benko called this the "headache ending."
Graham K. Burgess is an English FIDE Master of chess and a noted writer and trainer. He became a FIDE Master at the age of twenty. He attended Birkdale High School in Southport, Merseyside.
