1.Re8!!Qxe8
2.Qxf6!
The reverse move order does not work: 1.Qxf6 gxf6 2.Re8 Kg7 and of course 2... gxf6 3.Bxf6#
2...Qe7
The simplest way to win now is 3.Qxe7 Nxe7 4.Re1! Ng8 5.Re8 Be6 and the endgame is hopless for Black. However...
3.Qxg7+!!Qxg7
4.f6!Qxg2+
Another way of conceding was 4... Qf8 5.f7+ Ne5 and then White uses the power of the long diagonal to win by 6.fxe5 h5 7.e6+ Kh7 8.Bd3+ Kh6 9.Rf6+ Kg5 (9... Kg7 10.Rg6+ also leads to mate) 10.Rg6+ Kf5 11.Kf2!
5.Kxg2Bxh3+
6.Kxh3h5
7.Rg1
And Black resigned
