Lim Zhuo Ren (2155) - IM Suri Vaibhav (2430)
World Junior, Round 2, 3.8.2011

Analyzed by Centaur (Hairulov+Houdini)

1.d4 Nf6 2. c4 e6 3.Nf3 d5 4. g3 The Catalan - Zhuo Ren favorite opening.  

4...dxc4 5. Bg2 a6 6. O-O Nc6 7. e3  White concentrate on the center and did'not hurry to get the pawn back.  

7...Rb8 In order to play b5 next, black move his rook from the h1-a8 diaganol and white idea of playing Nf3-e5 is not strong anymore.  

8. Nfd2 e5 Black can't hold the pawn with 8... Na5?! because white will get it back with an edge after 9. Qa4+ c6 10. b4 cxb3 11. axb3 b6 12. b4 Nb7 13. Bxc6+

9. Bxc6+ bxc6 10. dxe5 Ng4 11. Nxc4 Be6 12. Nbd2 Zhuo Ren shows good opening preparation. This is all theory however.

12... h5 I'm not sure whether this is theory or not but it leads to an interesting sacrifice after  

13. h3 h4!?

 Black's sacrifiece his knight for an attack along the h-file. It's interesting to note that black's is yet to castle but willing to go for all out attack. His threat is on the h-file and the h1-a8 diaganol.  

14. hxg4 Our national champion decide to accept the challange.

14...hxg3 15. fxg3 Better is 15. Qf3 Threatening Qxc6+ and also covering the h1-18 diaganol. But probably white  wan to avoid a complicated and imbalance position after 15... Bd5 16. e4 Qh4 (Threatening mate on h2) 17. Qg2 gxf2+ 18. Rxf2 Bc5 19. exd5 Bxf2+  White's king look unconfortable but actually after  20. Kf1
cxd5 21. Nf3 The game is still far from over.

15... Qd3 16. Qf3 Houdini suggest 16.Kg2 Bd5+ 17. e4 Bxc4 18. Nxc4 Qxc4 19. b3 Qxe4+ 20. Qf3 And now black its force to exchange the queen.

16... Bd5 17. e4 Bc5+ 18. Kg2 Bxc4 19. Qxd3 Bxd3 20. Rf3 Rd8  21. a3  Be2 22. Rb3  Bxg4 23. Rc3 Bd4 24. Rxc6 Bh3+  25. Kf3 Bd7 26. Rxa6??

 A blunder , but the game is already difficult to save.

26... Rh2 Black threatening 27...Rf2++# checkmate so white has to play  27. g4 Be6?  Black missed a deadly move 27... Bb5! wish would  finishes off the opponent for e.g 28. Ra5 Rf2+ 29. Kg3 Bb6! 30.Rxb5 Rd3+  and  checkmate will follow in a couple of moves later.

28. a4 g5 29. Ra3?   

 Mistake come in pairs. White should try to complicate things and pray for the best with  29. Rxe6+ fxe6 30. Nc4  and white will have some chance , mainly his passed pawn on a file and black's weak  pawn.  

29... Bxb2 0-1 White resign because after  30. Bxb2 Rdxd2 He has to give  a piece to avoid being mate for e.g  any bishop moves 31. Bc1, 31.Ba1, 31.Bc3, 31.Bd4 all will be answer with 32...Rh3# checkmate.
