Is it possible to checkmate an opponent with a king and a pawn without the pawn promoting to a queen or rook? I've heard that it is possible, but I don't know what the strategy is.
The checkmated king is in one of his corners with one of his bishops on the same rank right beside him (blocking him). The checkmating pawn is in front of the bishop (checkmating the king) with the winning king two squares in front of the checkmated king on the same file protecting his pawn and blocking the checkmated king's move forward. Of course there can be no piece available to capture the checkmating pawn.
