White needs a drastic solution, since he is down in material and Black threatens axb2 as well as Qxg5 winning more material. 1.Bc1 would fix both, but after 1. … Qb4+ the situation becomes critical. However, there is a hidden mate-motif on the diagonal a1-h8:
1. Rxe5! Qb4 threatens mate;
1. … Bxe5
2. Qh8+ Bxh8
3. Rxh8#
1. … Qxe5
2. Bxe5 Bxe5
3. Qxe5 Ng7
4. Qh2 +-
1. … Qf8
2. Qh7#
Any other queen move results in the main variation:
2. Rxe8+ Rxe8
3. Qh8+ Bxh8
4. Rxh8#
1.Rxe5! wins. The main idea is 1…Bxe5 2.Qh8+! Bxh8 3.Rxh8#
If only the B on b2 could have a clear way to h8…then Qh8+, BxQ, RxB#.
So, clearing the way with Rxe5 while attacking the great black Q, seals the deal. Whatever black does it’s either loss of (heavy) material or mate.
If the black Q moves out of the way, Rxe8 with check, and mate will follow on h8.
Blocking the rook with Be6 doesn’t help, caus RxB again clear’s the way for Bb2 while the black Q is also under attack!
There’s just no good defense.
Readers did a nice job finding the lovely idea behind 1. Rxe5, however it looks like only HarryH saw through the crucial variation where Black replies 1… Be6
Note that 2. Rxe6 while thematic (opening the diagonal for the Bishop) doesn’t appear to work because 2…fxe6 creates a flight square for the King. So for example 3. Qh7+ Kf8 (avoiding 3…Kf7 right away when 4. g6+ Kf8, 5. Qh8+ Bxh8, 6. Rxh8 puts White on top again) Now the King has a flight square if 4. Qh8+ Bxh8, 5. Rxh8+ Kf7
But HarryH’s solution 2. Qh7+ Kf8, 3. Qxg7 seems to work and shows that the access to h7 turned out to be crucial after all, which seemed illusory because it didn’t play a part in any other variation!
Very lovely play. Took me a second try to find the 1. Rxe5 idea and then I got stumped by 1…Be6

By the way, after a Queen move like 1…Qb4 or 1…Qxg5, I think the move order with the immediate Queen sac also works 2. Qh8+ Bxh8, 3. Rx e8+ clears the way for the Bishop to exert its control over the diagonal in spite of being en prise (and in the case of 1…Qb4, being pinned!) 4. Rxh8 mate follows

wow, I’m quite rusty…did not see Rxe5….

Also by the way I think the resulting endgame after 1…Be6 in HarryH’s solution isn’t necessarily an easy win at least for me. With Black’s King nearby, there’s a very good chance Black can eliminate or at least exchange the g-pawn leaving pawns only on one side of the board. And then even if White could win the b-pawn, in a Rook and Pawn ending, I believe the RP/BP combination is often a draw.
