Mark Siew - Alfonso Ramos

Mark Siew (1978) - Alfonso Ramos

Asian Youth 2011, Round 4, 17.5.2011

Analyzed by Centaur (Hairulov + Fritz)

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. d3 b5 6. Bb3 Bc5 7. O-O d6 8. a4 Rb8 9. axb5 axb5 10. Bg5 h6 11. Be3 Bxe3 12. fxe3 





White's double pawn is not a serious liability to white. In fact white's rook on f1 get the open file on f-file. White's pawn on e3 also cover the important square - d4 and f4 which avoid black's knight to go to that squares.


12...O-O 13. Qe1 Be6 14. Nbd2 Bxb3 15. Nxb3 d5 16. Qc3 Probably better is 16. exd5 Nxd5 (16... Qxd5 17. Nh4) 17. e4 Nb6 18. Nh4


16... Qd6 17. Ra6 Rb6 18. Rxb6 cxb6 19. Nh4 b4 The problem with 19... dxe4?  is white have a nice tactical trick with 20. Nf5 Qe6 21. Qxc6! Qxc6 22. Ne7+ and white win a piece.


20. Qe1 g6?! Understandably black's doesn't want white's knight to go to the f5 square but his last move create more weakness on his kingside defense.


21. exd5 Nxd5 22. Qg3 Kh7 23. d4 Qe6 24. dxe5 Nxe5 25. Nd4 Qe7 26. e4 Nc7 27. Kh1 Rd8 28. c3 Nc4?! Black's should look after his defense first before committing his own attack  28... Qd6 29. Nhf3 Nxf3 30. Qxf3 Rd7 31. h4 bxc3 32. bxc3 h5 33. Qh3 Kg8 34. Kg1 Rd8 35. Qf3 Qe7 36. Qf4 Ne6



 29. Nhf5 !?  This looks interesting but a better option is 29. Nxg6!  fxg6 30. Nc6 Rf8 ( 30... Qd6? 31. Nxd8) 31. Rxf8 Qxf8 32. Qxc7+ White win some pawns.


29..gxf5 30. Nxf5 Qe5 31. Qh4 






31...Rd7??  The turning point. Black should give back material with 31... Rd6! which cover the weak h6 square and if white take the rook with  32. Nxd6 Nxd6  , white will have problem to continue his attack.


32. Nxh6 Qe6  32... Kg7 also lose to 33. Qg4+ Kxh6 34. Qh3+ Kg7 35. Qxd7 Qe6 36. Qxc7
winning material.


33. Nxf7+ It's mate in two. 33...Kg7 34. Qh8+ Kg6 35. Qh6# 1-0
