Figure 4.5.1.11[White to move]

This is structurally the same as the previous position; it's just a little different visually. Again there are two key facts here: the doubling of White’s rooks on the h-file, which is open, and the alignment of Black’s king and queen on the seventh rank. Rh7+ almost skewers Black’s king and queen, but the square is defended by Black’s knight. Once more the two rooks suggest the answer: play Rh7+, allowing the recapture NxR; then comes the other rook with RxN+, and Black is out of ways to keep a skewering piece off of h7. He moves his king and White takes his queen.
