1.Rh8+
Skewering the rook on a8 since the rook is untouchable: 1...Kxh8
2.Qh6+ Nh7 3.Qg7# 1...Kf7 2.Ng5+
2...Qxg5 Forced, since 2...Kg7 3.Rxa8 Qxa8
4.Qe7+ (double attack!) Kh6 5.Qxf6:

...is so clearly won for White. It is also preferable for Black
to the position in the analysis diagram below, after 3...Rxh8.
3.Qb3+ Taking the queen also wins, but not as
handily: 3.Qxg5 Rxh8
Analysis Diagram: after 3...Rxh8
Why is this position preferable to the one above it? Let's see
them side-by-side:
Analysis Diagram: after 5.Qxf6 |
Analysis Diagram: after 3...Rxh8 |
The position above left is preferable because White
has a 2-1 advantage in pieces, which makes his task of promoting a
pawn much easier than in the diagram above right, where Black can try
to coordinate his two pieces to work together against White.
I'm not saying Black has an advantage in the position on the right,
just that White's task is easier in the position on the left.
Now, back to the main line:
3...Kg7 4.Rxa8 Qg4+
Black hopes that White misplays, and allows a queen fork on the long
diagonal: 5.Ke3 Qe4+ picks off the loose rook. 5.Kf1
White declines to help Black out, and with an overwhelming material
advantage should have little trouble winning this ending.
