My best games (1)

GM Pascal Charbonneau was the reigning Canadian chess Champion back in 2006 and he did a tour of Canada together with IM Irina Krush (USA) to promote chess in a few Canadian cities from East to West. They stopped in Vancouver on June 10th, 2006 and both played at UBC in simuls (Irina in the morning, Pascal in the afternoon) against quite a few of us. I have rediscovered the records of my games with them. Here you can enjoy my victory versus Irina, one of the only 2 losses she recorded that day, with my original comments. Enjoy!

 [Event "Simul, Canadian Tour"] [Site "Vancouver, BC"] [Date "2006.06.10"] [White "Krush, Irina"] [Black "Demian, Valer-Eugen"] [Result "0-1"] [ECO "D36"] [WhiteElo "2437"] [BlackElo "2220"] 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. cxd5 exd5 5. Bg5 c6 6. e3 Be7 7. Bd3 O-O 8. Qc2 h6 9. Bh4 Nbd7 10. Nf3 Re8 11. O-O Ne4 12. Bxe7 Qxe7 13. Rae1 Ndf6 14. Ne5 {Strangely enough the same opening has been played identically a few boards to my left by Louie Jiang, a very promising local junior. Louie however lost in the endgame} Nxc3 15. bxc3 Ng4 {I cannot let Ne5 reign like that in the center} 16. Nxg4 Bxg4 17. f3 Be6 18. e4 dxe4 19. fxe4 Rad8 {White has a strong center which has not advanced yet. I decided on counter attacking "a2"} 20. Rf4 $6 {Not sure what was the idea behind this move} Qa3 21. Rf2 b5 22. Rb1 {Preventing b5-b4 and a weakening of the center} a6 {The threat was d4-d5 followed Bd3xb5 and e4xd5} 23. Qd2 a5 24. Bc2 $6 {The beginning of a dubious attacking plan on the Kingside. Black has enough tempi to gain material and come back to defend its King} Bxa2 25. Rbf1 Bc4 26. e5 Bxf1 27. Rxf1 Rxe5 {White's attack should involve a Bishop sacrifice on g6 and in that case the existence of a White pawn on "e5" makes a big difference. I decided to eliminate it at all costs} 28. Qd3 g6 29. Qf3 Re7 30. Qxc6 Rd6 $1 {No more sacrifices are possible now} 31. Qxb5 Kg7 {Putting the King on a dark square and working on the idea to exchange White's Rook. White's back rank becomes very weak once Rf1 disappears off the board} 32. Bb3 Rf6 33. Rb1 (33. Rxf6 Kxf6 {is hopeless}) 33... Qb2 $3 34. Bc4 (34. Rxb2 $4 Re1+ 35. Qf1 Rexf1#) 34... Qf2+
