In chess, the bishop and knight checkmate is the checkmate of a lone king by an opposing king, bishop, and knight. With the stronger side to move, checkmate can be forced in at most thirty-three moves from almost any starting position.
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 ...
Minor pieces get into play earlier than rooks, and they coordinate better, especially when there are many pieces and pawns on the board. On the other hand, rooks are usually blocked by pawns until later in the game. [59] Pachman also notes that the bishop pair is almost always better than a rook and pawn. [60]
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 ...
Often the mate is immediately preceded by a sacrifice that opens up the diagonal on which the bishop delivers checkmate, and the mate is often a pure mate (as is the case for all but one of the examples given here). The mate is named for Samuel Boden, who played a famous early example of it in Schulder–Boden, London 1853.
In all variations, the basic idea is the same: the queen and bishop combine in a simple mating attack, occurring on f7 for White or on f2 for Black. Scholar's mate is sometimes referred to as the four-move checkmate, although there are other ways for checkmate to occur in four moves.
