World Youth Under 16 Olympiad, Round 3, 24th October 2011
Analyzed by Centaur (Hairulov + Houdini)
1.d4 d5 2. c4 c6 3. cxd5 cxd5 4. Nc3 Nf6 5. Nf3 Nc6 6. Bg5?!
6.Bf4 is the usual move. Graham Burgess in his book The Slav give this move ( 6.Bg5) a ?! remark and mentioned that it gives Black very comfortable equality (at least) after
6...Ne4 7. Bd2 e6 8. e3 Bd6 9. Bd3 f5 10. O-O O-O 11. Be1 Rf6 12. g3 Bd7 13. Nd2 Rh6 14. f4 Rc8 15. Rc1 a6 16. Nf3 It seems that this rook has waste few tempos to return back to f8.
16...Rf6 16... Be8 With the idea of Bh5 later seems reasonable.
17. Ne5 Rf8 18. a3 Na7 19. Nxe4 fxe4 20. Be2 Bb5 21. Bxb5 Nxb5 22. Rxc8 Qxc8 23. Ba5 Na7 24. Qc1?!
I think this is a strategic mistake because after 24...Bxe5 25. dxe5 Qxc1 26. Rxc1 Nc6 Now black have a better endgame where his knight has more prospect compare to white's bishop in a closed position endgame
27. Bb6 h6 28. h4 g5 29. hxg5 Less advisable is 29. fxg5 hxg5 30. hxg5 Rf3 winning.
29... hxg5 30. b4 Kg7 31. Kg2 Rh8 32. Rh1?!
Another strategic mistake. White should keep the rook and try to open the position so that his bishop can shine against black's knight in open position. For e.g. 32. a4!? Nxb4 33. Rc7+ Kg6 34. Rxb7
32... Rxh1 33. Kxh1 Now black has a bad bishop versus strong knight endgame. White's pawn is on
the bishop color and the bishop can't become active.
33...Kg6 34. Kg2 Kf5 35. Kh3? 35. Bc5 this is the best bet to save the position.
35... gxf4 36. gxf4 d4!
Deflection: d4 37. Kg3
if a) 37. Bxd4 Nxd4 Combination 38. exd4 Kxf4
if b) 37. exd4 Kxf4 Deflection
37... d3?! there were better ways to keep up the pressure. Much stronger is 37... dxe3! 38. Bxe3 Ne7 again the knight is heading to d5 which left white bishop in zugzwang to protect the f4 pawn.
38. Kf2 Ne7 39. Ke1 Nd5 40. Bd4 Kg6 Why not going foward with 40... Kg4 41. Bc5 Kf3
41. Kf2 Kf7 42. Ke1 Ke7 43. Kd2 Kd7 44. Bc3? 44. Bb2 is necessary to prevent 44...Nb6 45. Kd1 Nc4 46. Bc1The bishop protect the a3 and e3 pawns.
44... Kc6 44... Nb6! is the fastest way to win 45. Kc1 Nc4 and one of the pawn ( a3 or e3) pawn will drop.
45. a4 Nb6 46. a5 Nd5 White is in zugzwang! 0-1 47. Bd4 Nxb4 winning.
