With the stronger side to move, checkmate can be forced in at most thirty-three moves from almost any starting position. [1] [2] Although it is classified as one of the four basic checkmates, [3] [a] the bishop and knight checkmate occurs in practice only approximately once in every 6,000 games. [4]
The checkmate utilizes a queen and bishop, where the bishop is used to support the queen and the queen is used to engage the checkmate. The checkmate is named after Pedro Damiano . One can also think of similar mates like 'Damiano's knight' and 'Damiano's rook' or even 'Damiano's king' (See Queen mate below), 'Damiano's pawn' or 'Damiano's ...
Two basic checkmate positions are shown with a bishop and a knight, or the bishop and knight checkmate. [40] The first position is a checkmate by the bishop, with the black king in the corner. The bishop can be on other squares along the diagonal, the white king and knight have to be on squares that attack g8 and h7.
A bishop moves any number of vacant squares diagonally. (Thus a bishop can move to only light or dark squares, not both.) The queen moves any number of vacant squares horizontally, vertically, or diagonally. A knight moves to one of the nearest squares not on the same rank, file, or diagonal. (This can be thought of as moving two squares ...
The defending bishop must maintain an attack on the pawn on the same color square as itself, so that the attacking king is not allowed to advance. If White pushes the other (unattacked) pawn, Black's bishop sacrifices itself for both pawns, with a draw. (If the second pawn is protected and advances instead, the position is also a draw.)
A bishop and knight can force mate, but with far greater difficulty than two bishops. In certain positions a bishop can by itself lose a move (see triangulation and tempo), while a knight can never do so. The bishop is capable of skewering or pinning a piece, while the knight can do neither. A bishop can in some situations hinder a knight from ...
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 ...
Portable Game Notation (PGN) is a text-based file format for recording chess games with support for annotative symbols, commentary, and background information, such as player names. It is based on short form English algebraic notation incorporating markup language. PGN transcripts, stored digitally as PGN files (suffix .pgn) can be processed by ...
