The triangle mate involves a queen, supported by a rook on the same file two squares away, delivering checkmate to a king that is either at the edge of the board or whose escape is blocked by a piece; the queen, rook, and king together form a triangular shape, hence the name of the mating pattern.
Left to right: king, rook, queen, pawn, knight, bishop. The rules of chess (also known as the laws of chess) govern the play of the game of chess. Chess is a two-player abstract strategy board game. Each player controls sixteen pieces of six types on a chessboard. Each type of piece moves in a distinct way.
which is stalemate (draw). Alternatively, if the bishop does not take the rook, then the white king has to move and White loses the advantage position. The winning method is as follows: 1.Rf8+! Re8 2.Rf7! Threatening to switch the rook to the other side and checkmate. 2...Re2. This is the best place for the black rook. Alternatives are:
(See § Check and checkmate.) A rook can move any number of squares along a rank or file. A rook is involved in the king's castling move. A bishop can move any number of squares diagonally. A queen combines the power of a rook and bishop and can move any number of squares along a rank, file, or diagonal.
There are also positions in which a king and a knight can checkmate a king and a bishop, knight, or rook; or a king and a bishop can checkmate a king with a bishop on the other color of squares or with a knight, but the checkmate cannot be forced if there is no other material on the board (see the diagrams for some examples).

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 ...
Positions with two rook pawns are often a draw. A position with a rook pawn and bishop pawn on the same side of the board is usually a draw if they are not far advanced, but the defense is difficult. Overall, the rook pawn and bishop pawn win in 61% of games. [85] The rook pawn and bishop pawn almost always win if they both reach their sixth rank.
In particular, if the pawn is on its sixth rank and is a bishop pawn or rook pawn, and the bishop does not control the pawn's promotion square, the position is a draw. [55] See Wrong bishop. A rook versus a minor piece: normally a draw but in some cases the rook wins, see pawnless chess endgame.
