Figure[White to move]

Instead of doubled rooks, White has a battery of queen and rook this time; but it can work the same way as the batteries we have just examined. White plays Qh8+, sacrificing his queen to BxQ—but clearing the way for the follow-up RxB+, and then after the Black king moves, RxQ. White gains a piece with the sequence (the Black bishop). Needless to say, you might have spotted the idea by just experimenting with checks (and then the new checks they make possible).
