Yeoh Li Tian (2278) - GM Nguyen Ngoc Truong Son (2647)Round 1, 19.3.2013, 3rd HDBank Cup Open International

Analyzed by Centaur (Hairulov+Houdini)

1.e4  e5 2. Nf3 Nc6 3. d4 The Scotch Opening - Li Tian Favorite! 

3...exd4 4. Nxd4 Nf6 5. Nxc6 bxc6 6. e5 Qe7 7.Qe2 Nd5 8. c4 Nb6 9. Nc3 Ba6 last book move according to my computer.  

10. b3 O-O-O 11. Bb2 Re8 12. f4 f6 13. Ne4 fxe5 14. fxe5


 White's e5 pawn is his strong point .

14...d5 15. Nd2 g6  if 15...dxc4 16. O-O-O! and white will have strong initiative

16. O-O-O Bh6 17. Kb1 Bxd2 18. Qxd2 dxc4 19. Qa5 Kb7 20. g3 It is look like black's king is
sitting in a dangerous diaganol h1-a8 especially after white play Bg2.  



Why on earth...?

21. Ba3 Qe6 22. Bxf8 Rxf8 23. Qc5! A strong move. White attack the rook on f8 and the black's vulnerable c6 pawn simultaneously. 23...Rf5
24. Bg2?!


 Look strong at first but actually it is a mistake. White should protect his e5 pawn and continue the presuree for e.g. 24. Re1 Rf7 (24... cxb3 25. Bxa6+ Kxa6 26. Qa3+ Kb7 27. Qxb3) 25. Rg1 Rd7 26. Ka1 Rd5 27. Qe3 Rd7 28. Qc3 Bb5 29. Rg2 cxb3 30. Qxb3 Rd5 31. Rf2 Nd7 32. Bg2 Nc5   

24... cxb3? Black return the favor. He should just eat the e5 pawn with 24... Rxe5!  25. Bxc6+ Kb8! (Of course not 25... Qxc6?? 26. Qxe5) 26. Rd8+ Bc8 And everything is fine for black.

25. Rhe1 Now white return to his driver seat.  

25...g5 26. Rd8 Rf6 indirectly overprotect the c6 pawn which is black's Achilles's heel.

 27. Be4!


Now white e5 pawn is threatening to capture black's rook on f6. Of course 27. exf6?? lost to 27...Qxe1+  

27... Rh6 Probably black should just take some material with 27... bxa2+

28. Rc1 Bc4? Again. Black is too generous. Why not eat the a2 pawn?  28... bxa2+  

29. axb3 Bxb3 30. Rd6! Equally strong is 30. Qf8!

30... Bd5 The rook is poison because if he took the bait then 30... cxd6?? and black will be mate on 6 (maximum). 31. Qxc6+ Ka6 32. Bd3+

 31. Bxd5?!  Li Tian almost spoil the game with this move. He should have just take the queen with 31. Rxe6 Bxe4+ 32. Ka1 Rxe6 33. Qd4 With a huge winning advantage.  

31... Qf5+  Now black is back into the game.  

32. Ka2 Rxh2+ 33. Ka3 cxd5??
