Some analysis, using Fritz 7b:

15.Nd6!?
   [15.Qxe2 +=
   ]
15...Nf8?
   [15...exf1Q+ 16.Rxf1 Bxd6 17.Qh7+ Kf8 18.Qh8+ Ke7 19.Re1+ Ne5!
      (19...Kf6 20.Rxe8+-;
       19...Be5 20.Qxg7 Rg8 21.Nxe5! Rxg7 22.Ng6+ Kf6 23.Rf1+ Kg5
       24.h4+ Kh5 25.g4+ Kxg4 26.Bd1+ Kh3 27.Rf3+ Kg4 28.Rf2+ Kh3
       29.Rh2+ Kg3 30.Rg2+ Kh3 31.Bg4#
      )
    20.cxd6+
       (20.Qxg7 Kd7)
    20...Qxd6 21.Qxg7 Kd8 unclear but maybe Black escapes
   ]
16.Nxf7! exf1Q+ 17.Rxf1 Bf5
   [17...Qd5 18.Bb3 Qxf7 19.Bxf7+ Kxf7 20.Qb3+ Kg6 21.c6! bxc6
    22.Qc2+ Kf7 23.Qxc6 Bd7 24.Qd5+ Kg6 25.Ne5+ +-
   ]
18.Qxf5 Qd7 19.Qf4 Bf6 20.N3e5 Qe7?
   [20...Bxe5 21.Nxe5 Rxe5
   ]
21.Bb3 Bxe5
   [21...Kh7 22.Qf5+ g6 23.Qxf6
   ]
22.Nxe5+ Kh7
   [22...Ne6 23.Ng6! Qd7 24.Qe4 c6 25.Nf8!
   ]
23.Qe4+ g6 24.Rxf8 1-0
