Tan Ken Wei - Saprin

It's a pity to see games from tournament like National Championship not being annotate by the players. Some probably think that annotating their own game will be a "suicide attempt" because you just reveal your opening repertoire , your strong and weakness to the "whole world".

How wrong they are ! The games of top players like Anand, Topalov, Kasparov, Carlsen and others are annotated LIVE and instantly  during and after the game but they STILL on top of the world!

I salute players like Mohd Saprin Sabri, Evan Capel and others who voluntarily sending their games to me to be annotated although i think many would prefer they annotated their game them self. Thanks to latest technology, patzer like me can annotated  games when they are beast like Rybka 4 on my side :)

Tan Ken Wei - Mohd Saprin Sabri
National Championship, Round 7, 19.6.2010

Analysed by Centaur (Hairulov + Rybka 4) 

1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. Nf3 Bg4 5. Be2 c6 6. Ng5  Bxe2 7. Qxe2 dxe5 8. dxe5 h6 This move just push white's knight to a better square on e4. Theory give 8...e6 which i think is more correct   

9. Ne4  e6 10. O-O Nd7 11. c4 N5b6 12. Rd1 Qb8  13. Bf4 13. f4!? also strong with the threat of f5 later 

13... a5 A start of an original maneuver 

14. Nbc3 a4 15. Qh5 Rybka suggest an interesting developing moves 15. Rd4!? Bc5 16. Rd3 Qa7  (16... Nxc4?? 17. Rxd7) 17. Rad1 The c4 is poison for black.

15... Ra5? (!) A typo. Actually this move is good. I mistakenly type - ? 

A quite strange but effective way of developing the rook in the middle game. Black avoid to take the poison pawn on c4 because after 15... Nxc4?? White have the deadly 16. Rxd7!  Kxd7 17. Qxf7+ Be7 18. Rd1+
And Rybka give mate in 14 - maximum!

16. c516. b3!? seems better.

16... Nxc5 17. Rd6!?  

17. Nd6+  Bxd6 18. exd6 Nbd7 19.Qg4 Kf8 is a possible continuation.  17... Nxe4?

The correct move is 17... Be7 18. Nxc5 g6 19.Qe2 Rxc5 Now white have the strong 18. Rxe6+! Be7 18...Kd8?? 19.Qxf7! 

19. Nxe4 Kf8 20. Rxe7! Another strong move by Ken Wei. He surely not  turning back. 

20...Kxe7 21. Nd6 Qg8 Black have to cover the f7 square. 

22. Bd2 Rd5   23. Bb4 23. Qh4+ f6 24. Nxb7 Qe6 25. exf6+ Qxf6 26. Qb4+ c5 27. Nxc5 Kf7  

23...c5 24. Ba5 Nd7 25. Re1 g6 26. Qh4+  g5?  26... f6 is the best way to defense although white is still on top after  27. Bc3 g5 28. Nf5+ 

27. Qc4? 27. Nf5+! Ke6 28. Qc4 Threatening 28...Ne3 

27... Rxe5 28. Rxe5+ The deadly tactician - Rybka 4 give 28. Nf5+! Kf6 29. Bc3 Kxf5 30. g4+ Kf6 31. f4 gxf4 32. Qxf4+ Kg7 33. Rd1 Qe8 34. Rxd7 Qxd7 35. Qxe5+

28... Nxe5  29. Qxc5 Ke6 30. Bc3 f6 31. Nxb7 Qc8 ?

31... Qb8! is the better square for the queen in this position because it will not be exposed to white's knight after for w.g . 32. Qb6+ Kf7 33. Nd6+ Ke7 34. Nf5+ Kf7 35. Nd6+ Ke6 36. Nb7+ Kf5 37. Nd6+ Ke6 38. Nb7+ =

32. Qd6+ ?  throwing away the advantage. 32. Qb6+ ! and white is on top 32...Qc6

(i) 32... Kd5?? 33. Qd6+ Ke4 (33... Kc4 34. Qd4+ Kb5 35. Nd6+) 34. Qd4+ Kf5 35. Nd6+  losing the queen

(ii) 32... Kd7 33. Qd6+ Ke8 34. Qxf6 winning

33. Nd8+ Rxd8 34. Qxd8 and white is better

32... Kf5 ! 32... Kf7  Is probably safer. 33. Qd5+ Kg7

33. Qb4?  33. f3 !? Is a viable option. Qxb7 34. Bxe5  fxe5 ?? 35. g4+ Kf4 36. Qd2+ Kxf3 37. Qg2+

33... Kg6 Black king is safe now.  

34. Nd6 Qg4  Now white have to trade queen to avoide black to have  the initiative 

35. Qxg4 Nxg4 36. Nc4 Rd8 37. g3 Kf5! Previously ,  black's king have to move around for shelter, now he move for attack! 

38. a3 Ne5  39. Nxe5 39. Nb6  If black choose to avoid the knight trade, black have a deadly threat with  39...Rd1+ 40. Kg2 g4 Threatening Nf3-Rg1++ checkmate! 

39... fxe5 40. Kg2 e4 41. f3 exf3+ 42. Kxf3 g4+ 43. Kg2 43. Ke2  Staying in the center is wiser although black is still winning. 

43... Ke4 44. h3 h5 45. hxg4 hxg4 46. Kf2 Rd3  Rd2+ 48. Ke1 Rg2 0-1
