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.
The second position is a checkmate on a side square next to the corner square (this position can theoretically occur anywhere along an edge, but can only be forced adjacent to a corner). 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 ...
A dead position is defined as a position where neither player can checkmate their opponent's king by any sequence of legal moves.

If one player castles kingside and the other queenside, it is called opposite castling or opposite-side castling. Castling on opposite sides usually results in a fierce fight, as each player's pawns are free to advance to attack the opponent's castled position without exposing the player's own castled king.
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.
