In the first diagram with White to play, White can force checkmate as follows: 1. Rxg7+ Kh8 2. Rxh7+ Kg8 3. Rbg7# For this type of mate, the rooks on White's 7th rank can start on any two files from a to e, and although black pawns are commonly present as shown, they are not necessary to deliver the mate.

Since mate by gold is a fundamental checkmate tactic in shogi, it is common for pieces to promote into a gold to deliver checkmate. [ 6 ] For instance, a silver defended by a pawn can mate at the head of a king but only if the pawn is promoted.
Less commonly (and obsolete), the warning garde can be said when a player directly attacks the opponent's queen in a similar way. This was mostly abandoned in the 19th century (Hooper & Whyld 1992:74). A move can be both check and garde simultaneously. Before the queen acquired its current move (about 1495) the rook was the most powerful piece.
A dead position is defined as a position where neither player can checkmate their opponent's king by any sequence of legal moves. [34] According to the rules of chess the game is immediately terminated the moment a dead position appears on the board. Some basic endings are always dead positions; for example: king against king;

With the side with the bishops to move, checkmate can be forced in at most nineteen moves, [ 35 ] except in some very rare positions (0.03% of the possible ...
Fool's mate was named and described in The Royal Game of Chess-Play, a 1656 text by Francis Beale that adapted the work of the early chess writer Gioachino Greco.

Three-check chess, also simply known as three-check, is a chess variant where a player can win by placing their opponent in check three times. Apart from this, standard rules of chess apply, including starting position and other ending conditions, such as stalemate and checkmate.
In the game of chess, perpetual check is a situation in which one player can play an unending series of checks, from which the defending player cannot escape. This typically arises when the player who is checking feels their position in the game is inferior, they cannot deliver checkmate , and wish to force a draw .
