  • 2011 Canadian Open R5 - games

    Some interesting finished round 5 games.

    The following game was played by 15xx-16xx players. What a nice attack by Black.

    Whole game
    [Event "Pinnacle 48th COCC 2011"]
    [Site "Toronto"]
    [Date "2011.07.13"]
    [Round "5"]
    [White "Sly, Douglas"]
    [Black "Zhang, John"]
    [Result "0-1"]

    1.d4 Nf6 2.Nf3 g6 3.Bf4 Bg7 4.e3 O-O 5.Bd3 d6 6.h3 Nc6 7.c3 Re8 8.e4 Nh5 9.Be3 e5 10.O-O d5 11.exd5 Qxd5 12.c4 Qd8 13.dxe5 Nxe5 14.Nxe5 Bxe5 15.Qc2 Qh4 16.Nd2 Bxh3 17.f4 Bxf4 18.Bxf4 Nxf4 19.Nf3 Qg3 20.Rf2 Nxg2 21.Rxg2 Qxf3 22.Rf2 Qg3 23.Kh1 Rad8 24.Bf1 Bxf1 25.Raxf1 Qh3 26.Kg1 Re3 0-1

    Position after Black 14...Bxe5

    A main threat - Bxb2 + a h3 pawn and a whole White King's side.

    After several moves (the last 16.Nd2)

    Black is ready to accomplish a destruction of the White King's pawn structure with Bxh3! (Does not work gh3 Qh3 (mate Qh2) f4 Qxe3+ )
    etc.

    Another game is a candidate for a biggest upset in two terms: rating (1897 vs 2277) and missed opportunities.

    Position after Black 35...Nd4

    White can not capture the knight Kxd4 as c2 and c1Q. However they could capture a pawn - Bxc3 and then Kxd4.

    White decided to get a passed pawn on 7 rank too :) (36. d7 Ke7)

    (Here White made a mistake with Kd3.) There was a possibility to grab a pawn (Bxc2) or ????

    an answer is here (mark with a mouse) << Kd4 c2 Ke4! c1Q Bf6+!! and d8Q end>>

      The following game held a theoretical dual.

      [Event "Pinnacle 48th COCC 2011"]
      [Site "Toronto"]
      [Date "2011.07.13"]
      [Round "5"]
      [White "Krush, Irina"]
      [Black "Zenyuk, Iryna"]
      [Result "1-0"]
      [WhiteELO "2578"]
      [WhiteTitle "WGM"]
      [BlackELO "2429"]
      [BlackTitle "WIM"]
      [Source "MonRoi"]

      1.d4 Nf6 2.Nf3 g6 3.c4 Bg7 4.Nc3 O-O 5.e4 d6 6.Be2 e5 7.O-O Nc6 8.d5 Ne7 9.Ne1 Nd7 10.Be3 f5 11.f3 f4 12.Bf2 g5 13.Rc1 a6 14.b4 Rf6 15.Nd3 b6 16.c5 Rh6 17.Kh1 Qe8 18.cxd6 cxd6 19.Bg1 Rb8 20.Nf2 Rg6 21.b5 a5 22.Na4 h5 23.Nd3 Kh7 24.Ndb2 Qd8 25.Nc4 Bh6 26.Qd2 g4 27.Naxb6 gxf3 28.Bxf3 Nxb6 29.Bxb6 Qg8 30.Bc7 Rxb5 31.Nxd6 1-0

      after 16...Rh6

      This position happened between the same players in San Louis 2011. White played cd6
      (1. d4 Nf6 2. Nf3 g6 3. c4 Bg7 4. Nc3 O-O 5. e4 d6 6. Be2 e5 7. O-O Nc6 8. d5 Ne7 9. Ne1 Nd7 10. Be3 f5 11. f3 f4 12. Bf2 g5 13. Rc1 a6 14.

Ne3 Be2 31. Nf5 Rg6 32. Ne7+ Kh8 33. Nxg6+ hxg6 34. Nd7 Bxf1 35. Nxb8 Bxb5 36. Nc6 1-0)

      This time white chose 17.Kh1 Qe8 18.cxd6 cxd6


      Even this position is not new.

      (le.g., [Event "Groningen op"]
      [Site "Groningen"]
      [Date "1999.12.28"]
      [Round "9"]
      [White "Atalik, Suat"]
      [Black "Kasimdzhanov, Rustam"]
      [Result "0-1"]
      [ECO "E99"]
      [WhiteElo "2598"]
      [BlackElo "2603"]


      1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5 7. O-O Nc6 8. d5 Ne7 9. Ne1 Nd7 10. Be3 f5 11. f3 f4 12. Bf2 g5 13. Rc1 Rf6 14. b4 Rh6 15. Nd3 a6 16. c5 Qe8 17. Kh1 b5 18. cxb6 cxb6 19. g4 fxg3 20. Bxg3 b5 21. Nf2 Nf6 22. Ng4 Rg6 23. a4 Bd7 24. axb5 axb5 25. Qd3 Rb8 26. Nxf6+ Rxf6 27. Qd2 Ng6 28. Qxg5 Qf8 29. Qe3 Bh6 30. Qa7 Bh3 31. Ra1 Bxf1 32. Rxf1 Bf4 33. Kg2 Rc8 34. Nxb5 Qh6 35. Qa2 Nh4+ 0-1



      After 26...g4

      Here followed (check a game notation)

      A Black's attack stuck, and White won on the Queen's side.

          21...Re8

          White defended (gigi) a rook with f6. After gxf6 he decided that he did not need
          that rook at all Rxf7!!

            First signs that players are getting tired or reducing the pace

            Bxc1. Queen is 9 points, while a R+B only 8 :) +/-


            Here I'll stop. Your move :)
