1. e4 c5 2. Nf3 a6 3. c4 Qc7 4. Nc3 e6 5. d4 d6 6. Be2 Nf6 7. O-O Be7 8. Bg5
Nbd7 9. h3 h6 10. Be3 e5 11. dxe5 dxe5 12. Nd5 Nxd5 13. exd5 f5 14. Ne1 

The knight has no prospects from this square. It is better to play 14. Nd2 O-O  15. f4 e4  16. Rc1  Bd6 17. Qe1  b6 18. Bh5 Nf6  19. Bg6

14... O-O 15. f4

White is fumbling around unsure what to do for the next few moves. 15. f3  followed by Qc2 and finding some way to re-activate the knight on e1 looked better

15... Bd6  16. fxe5 Nxe5 17. Nf3  Bd7 18. Bd2 Rae8 19. Bc3 Ng6 


Black control of the h2-b8 diagonal and dark squares gives him the advantage.

20. Bd3 Re3

Eng Chiam was already very short of time (maybe 5 minutes left) but continues to play good moves in the next few moves.

21. Qd2 Bf4 22. Qc2 Bg3 23. Bd2 Re7 24. Kh1 Nf4

This is inaccurate and allows white to  simplify the position.

25. Bxf4 

It is unclear why white gives up his bishop. Maybe he was just trying to capitalize on Eng Chiam's time trouble. Instead he could have simplified the position with 25. Nh4 ! Nxd3 26. Ng6 Re2  27. Qxd3  Rfe8  28. Nf4  Bxf4 29. Bxf4 

25... Qxf4 26. Ng1 Qg5 27. Ne2 Bd6  28. Rf3 Rfe8 

All black pieces on in their best possible squares!

29. Raf1 Re3

The more accurate move is 29...g6. There is no hurry to exchange pieces. In general principle, exchanges always ease the defender's task. Eng Chiam was down to about two minutes so it is hard to
fault him for seeking simplifications.

30. Qd1  g6 31. Rxe3 Rxe3 32. Rf3 

Wrecking his own king side pawns is a step towards the end

32... Rxf3 33. gxf3 Kf7 

Eng Chiam misses the stronger 33... Qe3  34. Ng1 Qf4 35. Qe2 g5  white is helpless against the two bishops and onslaught of  his king position.

34. Qc1 Qh4 35. Qf1 Qe7  36. Qc1 g5 37. b3 Qe5 38. Qg1 Qb2 39. Qb1 Qd2 40. Kg2 Kf6 41. Qc2 Qe3 42. Qd1 h5 43. Ng3 Qe5 

Both players were in time trouble now which explains the mistakes. Black have 43... Bxg3  44. Kxg3 f4+  45. Kg2 Bxh3+ ! 46. Kxh3  Qf2  and mate on g3!

44. Nf1 

44. Nxh5+ Kg6 45. f4  gxf4  46. Qg4+ Kh6 47. Qh4  Kg6 48. Qg4+ Kf7  49. Qf3  The dangerous black bishops are shut out and white will have a chance to survive

44... Qd4 45.Bc2 Qe5 46. Qc1 

Someone is bound to crack under the time pressure and it is white.

46... Qe2+ 47. Kg1 Qxf3 48. Qe3 Qxe3+ 49. Nxe3 

the rest is very simple

49... f4 50. Nd1 Bxh3 51. Nf2 Bf5 52. Bd1 g4 53. Kg2 Kg5 54. a3 f3+ 55. Bxf3 gxf3+ 56. Kxf3 a5 57. Ke3 h4 58. Kd2 h3 0-1
