Yeoh Li Tian, vs Lim De Li Derek
APPSO, 5.11.2010 

Analyzed by Centaur (Hairulov+Rybka 4)




1. e4 c5 2. c3 e6 3. d4 d5 4. exd5 White can transpose into a French Advance Variation with 4. e5  if  but Li Tian prefers to remain in Sicilian Alapin set-up. 


4... exd5 Usually black prefer to take the d5 pawn with his queen with 4...Qxd5 


5. Nf3 Be6 6. Bb5+ Nc6 7. O-O Bd6 8. Be3 Another option is to give black an isolated d-pawn with 8. dxc5 and after 8...Bxc5 9. Nbd2 with the idea of Nb3-Nbd4 to blockade the isolated d5 pawn. 


8... c4 9. Ba4 White can loosen black's center pawn with 9. b3 cxb3 10. axb39... a6 10. Re1. A positional player would prefer 10. Bxc6+ bxc6 11. b3 cxb3 12. axb3 which gave black weak pawns - a6 and c6 pawn. 


10... h6 11.Nbd2 Nge7 12. Nf1
  

A possible continuation is 12. Ne5 Bxe5 13. dxe5 and if 13...b5 14. Bc2 Nxe5 15. Bd4 And White has a strong initiative , however  White prefer to adopt the Ruy Lopez's maneuvering idea - Bb5-Ba4 - Bc2 and Nbd2-Nf1-Ng3 !?


12... O-O 13. Qd2 Ng6 14. Bc2 Nce7 15. Ng3 Bg4?! 16. Ne5! Nxe5 worse is 16... Bxe5 17. dxe5 Nxe5 18. h3 Be6 19. Bxh6  


17. dxe5 Bxe5 18. Bf4?! 18. Bxh6! straight away is stronger for e.g. 18... gxh6 19.Qxh6 f5 20.Rxe5 


18... Bf6?18... Bxf4 is correct for e.g. 19. Qxf4 Be6 with equal chance. 


19.h3 Be6 20. Nh5 Stronger is once again 20. Bxh6! Kh8 (20... gxh6?? 21. Qxh6 Ng6 22. Bxg6 fxg6 23. Qxg6+ Bg7 24. Nh5 Rf7 25. Rxe6) 21. Nh5 Ng8 22. Be3 and White is in control. 


20...Ng6 21. Bxh6!

Better late than never! 21...Re8 Of course 21... gxh6? Is worse after 22. Qxh6 Qe7 23. Bxg6 fxg6 24. Qxg6+


22. Nxf6+ gxf6 Unfortunately for Black, the natural move 22... Qxf6?? Will lose the queen after 23. Bg5! 


23. Qd4 another idea is the rook lift 23.Re3-Rg3 


23...Ne5?? In a very difficult position, Black commit a decisive mistake. 


24.Rxe5! Black resigns. 1-0

A stunning sacrifice by Li Tian. The end is near after 24...fxe5 25. Qxe5 f6 26. Qg3+ And black will be checkmate soon. Bravo Yeoh Li Tian!

Thanks to Li Tian's father - NM Yeoh Chin Sing for sending the games.
