Ne3! Rxh2 2. 0-0-0# A tablebase discovered that 1. h4 also wins for White in 33 moves, even though Black can capture the pawn (which is not the best move – in case of capturing the pawn black loses in 21 moves, while Kh1-g2 loses in 32 moves). Incidentally, the tablebase does not recognize the composer's solution because it includes castling ...
[13] [14] Chess-variant theorist Ralph Betza identified the 'leveling effect', which causes reduction of the value of stronger pieces in the presence of opponent weaker pieces, due to the latter interdicting access to part of the board for the former in order to prevent the value difference from evaporating by 1-for-1 trading. This effect ...
Board representation in computer chess is a data structure in a chess program representing the position on the chessboard and associated game state. [1] Board representation is fundamental to all aspects of a chess program including move generation, the evaluation function, and making and unmaking moves (i.e. search) as well as maintaining the state of the game during play.
The Lucena position is, incorrectly, named after the Castillian Luis Ramírez de Lucena, since the position does not appear in his book on chess, Repetición de Amores e Arte de Axedrez (1497). The earliest preserved discussion of the position is in Alessandro Salvio 's Il Puttino (1634), a romance on the career of the chess player Leonardo da ...
In 1895, Edward Freeborough edited an entire 130-page book of analysis of this endgame, titled The Chess Ending, King & Queen against King & Rook. [4]Because it has only four pieces, queen versus rook was one of the first endings to be solved by endgame tablebases. [1]
Chess pieces – two armies of 16 chess pieces, one army designated "white", the other "black". Each player controls one of the armies for the entire game. The pieces in each army include: 1 king – most important piece, and one of the weakest (until the endgame). The object of the game is checkmate, by placing the enemy king in check in a way ...
In the game of chess, an endgame study, or just study, is a composed position—that is, one that has been made up rather than played in an actual game—presented as a sort of puzzle, in which the aim of the solver is to find the essentially unique way for one side (usually White) to win or draw, as stipulated, against any moves the other side plays.
The chess endgame with a king and a pawn versus a king is one of the most important and fundamental endgames, other than the basic checkmates. [1] It is an important endgame for chess players to master, since most other endgames have the potential of reducing to this type of endgame via exchanges of pieces.
