In The Road to Chess Mastery (1966) by Max Euwe and Walter Meiden, the authors criticize Black's 25...d5, which led to the following position.

White to move

How does White exploit the error?

    R x p+, ...K x R, Rg1+ ...Kh8, Qh6

    Murray's start is correct, but what if black gives back material? For example, Ng6 or maybe Nxf5. If white plays 2. Qh6, then 2. ... Nxf5 seems right. I'm not 100% sure how to make progress for white. 3. Ng6+ (with the idea of Ne7 and the discovered check) looks clever, but it might be one of those moves that ends up not having a follow-up. It hits f5 once on e7, so white gets the night. That should be enough to do it, but I'm not really sure. I don't see a clear win, otherwise.

    Right, Ne7+ is double-check.

    1.Rxg7+ KxR, 2.Rg1+ Ng6, 3.f5xNg6 hxN (else 4.Qxh7+ Kf8, 5.g7 Rxg7 is forced, 6.RxR, then 7.Qh8 mate) 4.Qxg6+ Kh8 (...Kf8, 5.Qg8+ Ke7, 6.Rg7 mate), 5.Qh6+ Rh7, 6.Ng6+ Kg8, 7.Ne7+ (double-check and interfering w/defense of f6) Kh8 (...Kf7, 8.QxRh7+ Kf8, 9.Rg8 mate), 8.Qxf6+ Rg7, 9.QxRg7 mate.
