1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 dxc4 5. a4 c5? 6. d5 Bf5 7. e3 e6 8. Bxc4 exd5 9. Nxd5 Nc6 10. Qb3 White wants to directly refute Black's set-up.
Qd7 11. Nxf6+ gxf6 12. Bd2 Rg8 Black's pawn structure is damaged, but the semi-open g-file compensates him for this. 13. Bc3 Better was 13.0-0-0!? Be6, with slight advantage for White.
O-O-O 14. Bxf7?? This over-optimistic move allows Black to seize the initiative. White had to play 14.Rd1 or 14.g3. Rxg2 15. Nh4 Ne5! 16. Nxf5 Nd3+! Perhaps here White expected only 16...Nxf7 17.Qc2, where he could count on his strong knight. But Black does not have to take the piece back: 17. Kf1 Rxf2+ 18. Kg1 Kb8! Now White is doomed as his king is in a horrible position. 19. Qe6? More stubborn would be 19.Ng3, although after 19...Qc6 20.e4 c4 21.Qb5 Qxb5 22. axb5 Bc5 Black wins. A very cute, though not compulsory, position arises after 19...Bh6 20.Qe6? Qxe6 21.Bxe6 Bxe3 22.Nf1 Rg8+ 23.Bxg8 Nf4 24.Nxe3 Nh3#. Rxf5 20. h4 Bd6 21. Rf1 Rg8+ 0-1
