Subject: find the sac

From a recent Arasan game on ICC:

[D] r1bb1rnk/1pq2ppp/p3p3/4P3/2nNBB2/2N3Q1/P1P3PP/3R1R1K w - -

Bxh7 wins.

Crafty finds it after about 7 minutes on my XP2500+ but doesn't
give it more than a draw score:

               11     2:21  -0.21   1. Nb3 Ne7 2. Qh3 Nf5 3. Bxf5 exf5
                                    4. Nd5 Qc6 5. Qh5 Be6 6. Qf3 Bb6 7.
                                    Nxb6 Qxf3 8. Rxf3 Nxb6
               11->   3:40  -0.21   1. Nb3 Ne7 2. Qh3 Nf5 3. Bxf5 exf5
                                    4. Nd5 Qc6 5. Qh5 Be6 6. Qf3 Bb6 7.
                                    Nxb6 Qxf3 8. Rxf3 Nxb6
               12     4:13  -0.19   1. Nb3 Ne7 2. Qh3 Nf5 3. Nd2 Nce3 4.
                                    Bxf5 Nxf5 5. Nde4 Be7 6. g4 Nh4 7.
                                    Nd6
               12     6:08   0.01   1. Bxh7 Kxh7 2. Ne4 Nh6 3. Nf6+ Kh8
                                    4. Bxh6 gxh6 5. Qh4 Bxf6 6. exf6 Kh7
                                    7. Qe4+ Kh8 8. Qh4
               12->   6:36   0.01   1. Bxh7 Kxh7 2. Ne4 Nh6 3. Nf6+ Kh8
                                    4. Bxh6 gxh6 5. Qh4 Bxf6 6. exf6 Kh7
                                    7. Qe4+ Kh8 8. Qh4
               13     7:15   0.01   1. Bxh7 Kxh7 2. Ne4 Nh6 3. Nf6+ Kh8
                                    4. Bxh6 gxh6 5. Qh4 Kg7 6. Qg4+ Kh8
                                    7. Qh4

White can play 5. Qf4 instead with the line:
Bxh7 Kxh7 Ne4 Nh6 Nf6+ Kh8 Bxh6 gxh6 Qf4 Kg7 Rd3 Nxe5 Rh3 Rh8 Ne8+
winning the Queen.
