No, after Nf6+ gf Re8+ Kg7 black rook is controlling the f8 square as you can see.

Originally posted by !~TONY~!1. Nf7 Kxf7 2. Qxe6+! (2. ... Kxe6 3. Ng5 mate) of course!! But Black plays 2. ... Kf8 and then 3. Ng5 leads to the same position. Instead Black should play 1. ... Qc8 but then 2. Qxe6 with threat Nh6+ or maybe Nd6+ should be enough for the win?
Oh yeah, that's much better. 1. Nf7 Kf7 2. Ng5 and now:
2...Kg8 3. Qe6 just gets Black smothered mated after a few moves, but
2...Kf8 also sees black get mated.
Thus 1...Qmoves has to be tried, but 2. Qe6 and White will win easily.
hmm, looks like in my line white checkmates exactly in 7 moves:
1.Be5 Rxb2+ 2.Ka1 Rb1+ (otherwise in 6🙂) 3.Kxb1 Bxe5 4.Rg8+ Qxg8 5.Qxe5+ f6 6.Qxf6+ Qg7 7.Qxg7#.
edit: but I just noticed move 1...Rd6. let me think...
edit: No,1...Rd6 doesn't seem to change anything. Just 2.Bxd6 and no defense vs 3.Be5.
edit: oops...after 1...Rd6 2.Bxd6 there's Bh4! Need to think again.
edit: ok, 1.Be5 Rd6 2.Bxd6 Bh4 3.Rh4 Qf8 4.Be5+ f6 5.Bxf6+ Qxf6 6.Qb8+ Qf8 7.Qxf8#
Not sure I'm not missing anything again however.
edit 🙂 : And finally 2...Bg5 3.Rxg5 f6 4.Be5! fe 5.Rg8+ Qxg8 6.Qxe5+ Qg7 7.Qxg7#
The main line is 1. Be5! Rxb2+ 2. Bxb2 Bxb2 3. Rb4! Be5 4. Re4! Qf8 (what else?) 5. Rxe5 a5 6. Re8 with 7. Qg7 mate.
1. ... Rd6 2. Bxf6+ Rxf6 3. Re4! Qf8 4. Re8 Rg6 5. Rxf8+ Rg8 6. Qg7 mate
1. ... Rxf2 2. Bxf6+ Rxf6 just leads to the same, without the f2 pawn.
The position comes from Nunn - Murshed, 1985. The full game:
