1. d4 d5 2. c4 dxc4 3. Nf3 Nf6 4. e3 e6 5. Bxc4 a6 6. O-O c5 7. Qe2 b5 8. Bb3 Bb7 9. Rd1 Nbd7 10. a4 b4 11. a5 Qc7 12. Nbd2 Be7 13. Bc4 O-O 14. Bd3 Rfd8 15. h3 Nd5
My opening book give 15... h6 16. Ne4 cxd4 17. exd4 N7f6 18. Ne5 Nxe4 19. Bxe4 Nf6 20. Bd3 g6 21. Be3 Rdc8 22. Rdc1 Qd8 23. Nc4 black plan the obvious Nb6 forking black rooks 23...Nd5 24. Be4 Rab8 25. Bd3 not 25. Bxd5?! because after 25...Qxd5 black threaten mate on g2 and black have no serious problem after 26. f3 Rc7 25... Bc6 26. Ne5 Bb5 27. Bxb5 Rxb5 28. Qf3 Bf6 29. Rxc8 Qxc8 30. Rc1 Qe8 31. Ng4 Bg7 32. Nh6+ Bxh6 33. Bxh6 Rxa5

Although black is a pawn up, he has serious weakness on his king side's dark square 34. Qg3 Rb5 35. Qe5 f6 36. Qd6 Rb6 37. Qc5 Rb8? Yee Weng mistakenly let white's queen to penetrate black 7th rank 38. Qa7 white simply threaten mate on g7! 38...Ne7 39. Rc7 Now come another major pieces into black 7th rank ! 39...Nf5 40. Rg7+ ! This tempo gaining move is probably missed by Yee Weng. Maybe he taught that Nicholas will fall into a perpetual after the greedy 40. Rxh7 Ra8 41. Qb7 Rb8 42. Qc7 Rc8 = draw 40... Kh8 of course 40... Nxg7 ?? 41. Qxg7# checkmate 41. Rxh7+ Kg8 Now the bishop is free to move with a tempo 42. Bf4 Ra8 43. Qb7 Black does not have the perpetual 43...Rb8 because white's bishop simply guard the b8 square 43...g5 44. g4 Qg6 of course not 44... gxf4?? 45. gxf5 Qf8 46. Rh4 and black can simply resign 45. gxf5 exf5 46. Qxa8+ Kxh7 47. Qb7+ Kh6 48. Bd6 a5 49. Qc8 Qf7 50. Qxf5 1-0
