With the help of Gambit Tiger 2.0 on 1.2 GHz AMD:
1... Bxf6 2. Rxf6 bxc3 3. Rxc3!
( 3. Bxg7? Qc5+ !
( 3... h5 ?! 4. Qg5 Qc5+ 5. Qxc5 dxc5 6. Bxf8
( 6. Rxd7 Kxg7 7. Rf1 Nf6 Black is better. )
6... Nxf6 7. Bxc5 cxb2 8. Rd1 Nxe4 9. Bd4 Ba4 10. Bxa4?
( 10. Bxb2 Bxb3 11. cxb3 Rc8 = )
10... Rd8 Black wins. )
4. Kh1 h5 5. Qg3 Nxg7 6. Rxc3 Qe5 Black is better. )
3... Qa5 4. Rf2 Qe5 5. Bg5 Rb8 6. Rg3
( 6. Be7 f5 7. exf5 Rf7 8. Bh4 also works. )
6... Rb4 7. Bf6 Rxe4 8. Qxg7+ Nxg7 9. Rxg7+ Kh8 10. Rxf7+ Qxf6 11. Rxf8+ Qxf8
