This is the move that Saavedra introduced. White threatens 7. Ra8+ and mate. Material is even, but the unfortunate positions of Black's king and rook doom him to a loss. 6... Ra4 7. Kb3. Black must either lose the rook (allowing White an elementary checkmate) or be checkmated by 8.Rc1. [3]
The black king starts on e8, directly across from the white king. Each king starts on a square opposite its own color. A king can move one square horizontally, vertically, and diagonally unless the square is already occupied by a friendly piece or the move would place the king in check.
Black must now address the check; the fact that the bishop cannot legally move is irrelevant. If the king is in check and the checked player has no legal move to get out of check, the king is checkmated and the player loses. Under the standard rules of chess, a player may not make any move that places or leaves their king in check.
The black king can be on any square on the edge of the board, the white king is in opposition to it, and the rook can check from any square on the rank or file (assuming that it cannot be captured). The second diagram shows a slightly different position where the kings are not in opposition but the defending king must be in a corner.
After this move, White cannot prevent the black king escaping the b1–h7 diagonal. The black king can play up the g-file to g6 and the white king has no option but to follow with opposition on the e-file to at least e5, otherwise the black king can escape to the third perimeter at f5 or f6. 83... Kg4 84. Be4. The black king can now escape to ...
Mayet's mate involves the use of a rook attacking the black king supported by a bishop. It often comes about after the black king castles on its kingside in a fianchetto position. White usually arrives at this position after a series of sacrifices on the a-file or h-file. It is a type of Anderssen's mate and closely resembles the Opera mate.
If a player's king is placed in check and there is no legal move that player can make to escape check, then the king is said to be checkmated, the game ends, and that player loses. [22] Unlike the other pieces, the king is never captured. [23] The diagram shows an example checkmate position.
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.
