Sacrifice Example II

In the position below White institutes a mating attack by (1) P-f6. The only move to protect the mate on g7 is P-g6. It will then be White's desire to enter with its Queen on h6 again threatening the checkmate on g7. He will, therefore, play either Q-f4 or Q-g5. Black has no other way to defend himself against White's threat than by K-h8 followed by R-g8. But after K-h8; Q- h6, R-g8 White plays R-f3 and Black is unable to prevent White from sacrificing its Queen on h7 and mating by R-h3.

If Black's Queen were standing on c5 instead of b5 he could avert the mate by moving the Rook f8 and playing the Queen to f8 thereby protecting g7.
