Sacrifice Example I

In the game below, White on the move can play for a mate by placing its Rook on g3. The best protection against Rxg7 which Black has at its disposal is P-f6. But if he does not know the mating position illustrated in Diagram 29 he is liable to play P-g6, and then White forces the mate by sacrificing its Queen on h7.

(1) R-g3 P-g6
(2) Qxh7+ Kxh7
(3) R-h3+ K-g8
(4) R-h8+
Black could have prolonged the agony one move by interposing its Queen on h4 on the third move.
