The checkmate is delivered by a rook with the queen's assistance. The rook is adjacent to the king, while the queen supports the rook, being separated from it by one empty square on the same diagonal as the rook. This forms a 3 by 3 box shape, inside which the enemy king is trapped.
Normally, the winning process involves first winning the rook with the queen via a fork and then checkmating with the king and queen, but forced checkmates with the rook still on the board are possible in some positions or against incorrect defense. With perfect play, in the worst winning position, the queen can win the rook or checkmate within ...

In chess, a back-rank checkmate (also known as a corridor mate) is a checkmate delivered by a rook or queen along the opponent's back rank (that is, the row closest to them) in which the mated king is unable to move up the board because the king is blocked by friendly pieces (usually pawns) on the second rank.
A back-rank checkmate is a checkmate delivered by a rook or queen along a back rank (that is, the row on which the pieces [not pawns] stand at the start of the game) in which the mated king is unable to move up the board because the king is blocked by friendly pieces (usually pawns) on the second rank.

A king and three ferzes can force checkmate on a bare king if not all three ferzes are on the same square color; a king and two ferzes on opposite-colored squares can force stalemate on a bare king, [2] but not easily, and they cannot force checkmate. The endgame of rook versus ferz is a win for the rook.
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.
