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.
(It would still be drawn by perpetual check with the queen on f1 through f4, but it is won with the queen on f5 by the plan of getting the White king to h6, which no longer causes stalemate.) [15] Finally, diagram 3 has the defending king immobilised in the corner by the enemy queen a knight's move away, so the rook may give perpetual check ...
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.

In chess, an ideal mate is a checkmate position that is a special form of model mate.While in a model mate, each piece on the mating player's side (possibly excluding the king and pawns depending on context) participates in the mate, an ideal mate involves all the pieces of the mated player's as well, typically by blocking the mated king's field of movement so that it cannot escape.
Depth to mate (DTM) – The game can only be won by checkmate. Depth to conversion (DTC) – The game can be won by checkmate, capturing material or promoting a pawn. For example, in KQKR, conversion occurs when White captures the Black rook. Depth to zeroing (DTZ) – The game can be won by checkmate, capturing material or moving a pawn. For ...
