First I thought it had to be 1. Rf7+, seemingly the only move to defend g pawn, staying a pawn up.
White is slightly better, but I was unable to see something decisive after that.
So I guess that my bishop being on same diagonal as black king has something to do with it. 1. Bxe5+ does not look good, but what about:
1. Rxe5!
Yes, of course. This has to be it. Now I allmost instantly see:
1. … dxe5 (not taking was hopeless)
2. Bxe5+ Kg8
3. Bxh8!
Here I first tried g7 right away but it turned out to be wrong. Queen for 2 rooks is too equal.
3. … Kxh8
4. g7+ Kg8 (Kh7 Rf8 and the pawn queens)
5. Rf8+ Qxf8
6. gxf8=Q+ Kxf8
7. Qb6+
Taking the rook and game is over.
Illustrates why 3. Bxh8 was necessary. Bishop staying on e5 had prevented Qb6+.
1. Re5
Rf5
Main idea is simple, but there are a lot of sub-variations, which I doubt anyone would completely see OTB before playing the 1st move.
First move is 1. Rxe5 to which there are 2 tries: 1. .. dxe5 and 1. .. Be3+
1. .. dxe5 2. Bxe5+ Qxe5
(2. .. Kg8 3. Qb3+ Rf7 4. Rxf7 Be3+ 5. Kb1 Qxe5 6. Rf8+)
3. Qxe5+ Kg8
(3. .. Kxg6 4. Qxh8)
4. Qd5+
(4. Qb8+ Kg7 5. Qxa7+ works here as well, but White does better with 4. Qd5+)
4. .. Kg7 5. Rf7+ Kg8
(5. .. Kxg6 6. Qf5#)
(5. .. Rxf7 6. Qxf7#)
6. Rxa7+ Kf8 7. Qf7#
1. .. Be3+ 2. Qxe3 dxe5 3. Qxb6 Re7 4. Qf6+ Kg8 5. Rf5! Re6 6. Rxe5 Rxf6
(6. .. Rxe5 7. Bxe5)
(6. .. Qxg6 7. Qd8+ Kg7 (7. .. Kh7 8. Qd7+) (7. .. Kf7 8. Qd7+) 8. Rxe6+)
7. Rxe8+ Kg7
(7. .. Rf8 8. Rxf8+ Kxf8 9. g7+)
8. Bxf6+ Kxf6 9. Rxh8
Another comment from Lucy:
I see that after 1. Rxe5 Be3+ 2. Qxe3 dxe5 3. Qxb6 Black has 3. .. Rf8 in addition to 3. .. Re7, which I listed previously.
3. .. Rf8 4. Bxe5+
(4. Qxa7+ not as strong, since White wants to pick up BOTH Black rooks)
4. .. Qxe5
(4. .. Kg8 5. Rxf8+ Qxf8 (5. .. Kxf8 6. Qf6+ Rf7 (6. .. Kg8 7. Qh8#) 7. gxf7 Qxf7 8. Qd8+ Qe8 9. Qxa5) 6. Qe6+ Rf7 7. Bd6 Qg7 8. Be5 Qf8 9. Bf6 h5 10. Kb1 h4 11. e5 h3 12. gxh3 is cute.)
5. Qxa7+ Kxg6 6. Rxf8
