Round 10 : Alan Young - Gregory Lau

Alan Young - Gregory Lau
39th Olympiad, Round 10, 1.10.10

Analysed by Centaur (Hairulov+Rybka 4)

1.e4 e6 2. d4 d5 3. Nc3 Nf6 4. Bg5 Be7 5.e5 Nfd7 6. h4
This is one of the aggressive line in French Defense and it is call Alekhine-Chatard Attack. White offer a pawn sacrifice and if black accept it, white will have a good compensation after for e.g. 6...Bxg5 7.hxg5 Qxg5 8.Nh3!?Qe7 9.Nf4 Nc6 10.Qg4 6...a6 A wise choice. Even top GM declined to accept the pawn as variation mentioned before. 7. Qg4 Kf8!? I'm surprised that Rybka opening book didn't mention this move at all. The move is quite common seen in French classical line. 8. Nf3 c5 The thematic answer for flank attack is to attack the center! 9. dxc5 Nc6 Black can always capture the c5 pawn later. 10. Qf4 Nxc5 11. Rh3 Former World Champion - Gary Kasparov has frequently used this idea in this type of position - with deadly effect! 11...b5 12.Nd4 White move his knight to make way for the rook to join the attack, for e.g by playing Rf3 - attacking the vulnerable f7 square. 12...Nxd4 13. Qxd4 Nd7 14. O-O-O Bxg5+ 15. hxg5 Qxg5+ 16. f4 White sacrifice a pawn for the initiative.
16...Qe7 17.f5 Bb7 18.Rf3 The idea behind 11.Rh3 is clear now. 18... Rc8 19. a3 exf5
20. Rxf5 Qe6 21. Qf4
21...h6 21...g6! is stronger because after 22.Qh6+Kg8 23.Rf2 Qxe5 black win the e5 pawn 22. Bd3? 22.Na4 is the correct move because after 22...g6 white can play a strong idea 23.Nd4 Qe6 24.e6!? 22... g6 23. Qb4+ Kg7 24. Rff1 Nxe5 Black is two pawn up now.
25. Qd4 Rc7 26. Rde1 f6 27.
24...Re7 Rybka suggest a strong tactical move 27... d4! 28. Qxd4 Rd7 29. Qf2 Rxd3 30. Rxe5 Qxe5 31. cxd3 with a winning advantage for black. 28. Kb1 h5
29. Qg3 Rh6 30. Qf2 Qd6 31. Qd4 Rh8 ? 32. Ne4!

32...Nc6?? Greg is in severe time trouble and blunder big time. 32... Qe6 is the correct move and after 33. Nxf6
Rf8 it is still playable for both side. 34. Nd7 Rxf1 33. Nxd6 Rxe1+ 34.
Rxe1 Nxd4
35. Re7+White win a piece. 35.Nxb7 also the same 35...Kh6 36. Nf7+
1-0 Black resign
