Subject: Help with this interesting position?

Author: James Robertson

Date: 21:26:37 11/05/98


The following position was reachied in a blitz game between Exchess 2.49 and
SSEChess 2.01:

4rrk1/ppp2pp1/2qp3p/2n5/2P1PQ1B/3P4/P1P3PP/R4RK1 w - -

Exchess played Qf2 and won about 30 moves later, but I thought that maybe Bf6
would be an irresistible sacrifice for a computer program.

After 1. Bf6 gxf6 2. Qxh6, I don't see any way Black can win:

2. ... Nd5 3. Rf3 Ng5 4. Rg3 d5 5. h4 Qd6 6. Kh2 Qe5 7. hxg6 fxg6 8. Qxg6+ Qxg6
9. Rxg6+ Kh7 10. cxd5 (evaluated -2.15 for Black by Crafty)

2. ... Nd7 3. Rf3 (And Black can't stop Rg3)

Since my computer is kind of slow, I am not sure that I am not missing
something. Could somebody with a really fast computer analyze this and see if
there is any way Black can escape without major material loss after accepting
the sacrifice?

All comments welcome! Thanks!

James
