    A variant first described by Claude Shannon provides an argument about the game-theoretic value of chess: he proposes allowing the move of “pass”. In this variant, it is provable with a strategy stealing argument that the first player has at least a draw thus: if the first player has a winning move in the initial position, let him play it, else pass.

  3. Checkmate pattern - Wikipedia

    en.wikipedia.org/wiki/Checkmate_pattern

    Vuković’s mate is a mate involving a protected rook which delivers checkmate to the king at the edge of the board, while a knight covers the remaining escape squares of the king. The rook is usually protected with either the king or a pawn.

  4. Chess piece relative value - Wikipedia

    en.wikipedia.org/wiki/Chess_piece_relative_value

    Although the 1-3-3-5-9 system of point totals is the most commonly given, many other systems of valuing pieces have been proposed. Several systems treat the bishop as slightly more powerful than a knight. [19] [20] Note: Where a value for the king is given, this is used when considering piece development, its power in the endgame, etc.

    en.wikipedia.org/wiki/Software_for_handling...

    This article covers computer software designed to solve, or assist people in creating or solving, chess problems – puzzles in which pieces are laid out as in a game of chess, and may at times be based upon real games of chess that have been played and recorded, but whose aim is to challenge the problemist to find a solution to the posed situation, within the rules of chess, rather than to ...

  6. Checkmate - Wikipedia

    en.wikipedia.org/wiki/Checkmate

    A checkmate may occur in as few as two moves on one side with all of the pieces still on the board (as in fool's mate, in the opening phase of the game), in a middlegame position (as in the 1956 game called the Game of the Century between Donald Byrne and Bobby Fischer), [3] or after many moves with as few as three pieces in an endgame position.

  7. Chess scoring - Wikipedia

    en.wikipedia.org/wiki/Chess_scoring

    The games played is the sum of the "for" and "against" scores, so in this case, Fischer scored 18½ points from 23 games played. +W −L =D: W wins, L losses, D draws "Fischer 6.5/9 (+5 −1 =3)", meaning Fischer scored 5 wins, 1 loss and 3 draws for a total of 6.5 points out of 9. [3] +A or −A: Number of wins minus number of losses

  8. King and pawn versus king endgame - Wikipedia

    en.wikipedia.org/wiki/King_and_pawn_versus_king...

    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.

  9. Game complexity - Wikipedia

    en.wikipedia.org/wiki/Game_complexity

    Game-tree complexity of a game is the number of leaf nodes in the smallest full-width decision tree that establishes the value of the initial position. [1] A full-width tree includes all nodes at each depth. This is an estimate of the number of positions one would have to evaluate in a minimax search to determine the value of the initial position.
