Sacrifice Example III

A mate with Rook and Knight is liable to occur in several variations of the play which might result from the following situation:

								8
								7
								6
								5
								4
								3
								2
								1
a	b	c	d	e	f	g	h

White starts its mating attack with (1) Kt-f6. This threatens the sacrifice of the Queen on h6 followed by R-g8 mate. White's Knight move can hardly be called a sacrifice as it is quite evident that Black cannot take the Knight on account of Qxh6+, Kt-h7; Q-g7 mate. The only way to parry White's threat is (1) ..., Kt-g6. However, this helps only momentarily as White continues (2) R-h3 threatening Q-g5, Rxh6+ and Qxh6 mate, a threat against which Black has no defense. White can very nearly force the mate by sacrificing its Queen on h6 instead of the Rook. But after (3) Qxh6, Pxh6; (4) Rxh6+, K-g7; (5) R-h7+, K-f8; (6) R-h8+ Black does not take the Rook as White would like him to do to enable the mate R-g8, but he goes back to g7 with the King and White could not do any better than draw by perpetual check on h7 and h8.
