1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. f4 Nc6 7. Be3 Be7 8. Qf3 e5 9. Nxc6 bxc6 10. f5 O-O 11. O-O-O Qa5 12. Bc4 Bb7 13. g4 d5 14. g5 dxc4 15. gxf6 Bxf6 16. Rd6 Rfd8 17. Rxf6 gxf6

According to O'Reilly, here White had only used 10 minutes and was 1 hour ahead on the clock.

18. Bh6 Kh8 19. Qg3 Rg8 20. Qh4 Qd8 21. Ne2

White had intended 21. Rd1 Qe7 22. Rd7 but now saw that 22... Rg1+ forces off Rooks (O'Reilly).

21... Qe7 22. Ng3 c3 23. Kb1 Ba6 24. Nh5 Rab8

My computer engine suggests 24... Rg5, which would seem to end the attack. All White can do is get his sacrificed exchange back with 25. Bxg5 fxg5 but after 26. Qe1 cxb2 Black should win.

25. b3 Rg2 26. Nxf6 Bd3

This loses the game. Instead 26... Rbg8 draws (O'Reilly).

27. Bg5

Accepting the Bishop sacrifice with 27. cxd3 would have given Black the win after a follow-up Rook sacrifice on b3.

27... Rxb3+ 28. Ka1

If White accepts the Rook sacrifice with 28. axb3, then 28... Bxc2+ leads quickly to checkmate. However by declining it, it was Black who had to resign with checkmate inevitable.
