Sacrifice Example VI

Sacrifices with the view to utilizing a pin occur in various other versions which are essentially different from the one illustrated above. Following are typical examples of the three most frequent cases.

In the position below Black must not take the Pawn e4 although he can protect the Knight with B-f5 in case White pins him with R-e1.

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

The way in which White would obtain the advantage is this:

(1) R-e1 B-f5
(2) Rxe4 Bxe4
(3) R-e1

Through sacrificing one Rook for the Knight White has freed the square e1 for the other Rook who now pins the Black Bishop without Black being able to protect it.
