1. d4 d5 2. c4 c6 3. e3 Nf6 4. Bd3 e6 5. Nf3 Nbd7 6. Nbd2 c5 7. O-O cxd4 8. exd4 dxc4 9. Nxc4 Be7 10. Bf4!
   Later I found a few games where White developed bishop to g5, which makes little sense here. With the knight on c4 it's better to play on the queenside.
O-O 11. Rc1 Nd5
    Better was 11...Nb6 12 Nxb6!? Qxb6 13 Qc2, with some advantage to White.
12. Bg3 N7f6 13. a3!
   In many variations it is very useful to control the b4-square. Here my opponent failed to find a suitable plan.
h6?
    This makes no sense, although White would be better after both 13...Bd7 14 Qb3 b6 15 Nce5 and 13...b6 14 Nce5 Bb7 15 Qa4.
14. Re1 Ne8 15. Bb1 f5 16. Be5 Nef6 17. Ba2!
   Once Black blocks the b1-h7 diagonal, it is very good to bring this bishop to the neighbouring one.
Re8 18. Ne3
   I also considered 18 Bxf6 Bxf6 and then 19 Nce5 or 19 Ne3. Playing 18 Ne3 I had to foresee White's 21st move.
Nxe3 19. Rxe3 Nd5 20. Bxd5! Qxd5
   Black had to play 20 ..exd5, although after 21 Bc7!? Qd7 22 Ne5 Qe6 23 Nc6 Qf7 24 Nxe7+ Rxe7 25 Rxe7 Qxe7 26 Be5 he position would have remained very difficult.
21. Bxg7! Kxg7 22. Ne5+- Bg5 23. Qh5
   Even better was 23 Rc7+! Re7 (or 23.. ..Kh8 24 Qh5) 24 Rxe7+ Bxe7 25 Qh5, winning. However, I saw one winning line and did not bother to search for yet another.
Re7 24. Rg3 Qxd4 25. Rxg5+ hxg5 26. Qxg5+ Kf8 27. Qf6+ Kg8 28. Qxe7 Qxe5 29. Qd8+ Kf7 30. Rc7+ Bd7 31. Qxd7+
