DATCC 2009 MY Annotated game

I would like to ask for forgiveness for my compatriot blogger - Khairunnisa for showing this game. Actually before the game  start, we plan not to show it   in our blog. However i felt "guilty" not to share my game but  at the same time show and annotated others game. 
Below is our 2nd round  game. I played for my team - Nusa Mahkota Chess Club vs Persatuan Catur Wanita Malaysia (PCWM) .  We play on board 3. 

Hairulov  vs NWM Khairunnisa Wahiduddin
Round 2, DATCC Team League 2009, 29.4.2009

1. d4 Nf6 2. Nf3 e6 3. Bf4 d5 4. e3 Be7 5. h3 I choose to play this move because i want to keep my black square bishop to control the e5 square and to have an attacking posibilities if black play h6 later. If black have'not play Be7 earlier,  i will not play h3 because black can exchange it straight away with Bd6 and h3 will look like a waste of a tempo. But now if black choose to exchange it with Bd6, she at least has to waste a tempo.    5...O-O 6.Bd3 c5 7. c3 Nc6 8. Nbd2  cxd4 I think black should not release the tension in the centre too early. 8...b6 is better followed by 9...Bb7 9. exd4 9.cxd4?! will be a positional mistake because black can use the open c - file to her  advantage with move like Bd7-Rc8-Nb4 9...h6 10. O-O Bd6 11. Ne5!

This is my plan. Using and overprotecting the e5 square.11...Qc7 12. Re1 Nd7 13. Qh5 During the post game analysis with my opponent , i taught this move was not accurate and i should have played patiently with  13.Nf3. However at home, Fritz "said" 13.Qh5 is good and best. 13...f5 14. Ndf3 alternative 14. Nxc6 bxc6 (14... Bxf4? 15. Ne7+ Kh7)
and now 

a) 15. Bxh6!?  look strong at first but it seems that black can defend the attack after 15...Nf6 16. Qg6 Nh7  (Threatening 17...Rf6)   17. Nf3 (17. Be3 and black can force a draw with  17...Rf6 18.Qe8+) 17... Rf6 18. Qe8+ Rf8 19. Qg6 =

b) 15.Bxd6 Qxd6 16.Nf3 with  probably small advantage to white 

14... Nf6 I have a long think after black 14th move. I considered two option 15.Qg6 and 15.Qh4

a) i don't like 15.Qg6 because it seems that my queen will be harass after 15...Ne7 16. Qg3 Nh5, however i should have not be so afraid because after 17.Qh4 black can't reply with 17... g5  because black knight on h5 is hanging and white is probably better.  

However in the game i choose the second option which involve a rather speculative sacrifiece  15. Qh4!? this move invite black to play 15...g5 winning a piece for two pawn. But white have a strong  initiative. 
16.Nxg5 hxg5 I consider two option here :- 

a) 17. Qxg5! which i reject immedietly after 17...Qg7 thinking that my attack will not last long. However i should have look deeper  as what  Fritz  suggest  after for e.g  18. Qh4 Re8 
(18... Qh7 19. Bh6) 19. Bh6 Qh8 20. Qg5+ Kh7 21. Qg6# 

 b) the move i choose 17.Bxg5  Bxe5 If 17... Nxe5 I planned to play 18. dxe5 Bxe5 19. Rxe5! Ne4 (Of course not 19... Qxe5 ?? 20. Bf4 The queen will be trap) 20. Bf4 
and later push c4 or g4 to release my rook on e5 18. dxe5 Nh7  19. Bf4 
I choose to protect my achilles hill square on e5 . Actually 19.Bh6 ! is stronger. I consider this move in my calculation but i don't want black to put his rook on the 7th file after 19...
Rf7. Actually putting the rook on 7th file  doesn't help black so much because after
white play the rook lift Re3-Rg3 and black play Kh8 white can then play
Bg5-Bf6 as what happen in the game later . 
 19... Qf7? correct is   19... Kh8  preparing 20...Rg8 which will avoid Bg5 by white and before white control the g-file with the rook lift Re3-Rg3   20. Re3 Kh8 21. Rae1?!  I should have play 21. Bg5!  Straight away. The problem is...i didn't see it :)   21... Bd7? Black choose to activate his rook on a8 quickly but she should stop Bg5 first with  21... Qe7  22. Bg5! Now i find it :)
  After this i was confident that my position is winning. Black king is stuck in the corner and white is threatening the deadly Bf6 and Rg3  22...Qe8 23. Rg3 Nxe5 Black choose to give back the material to loosen the bind on her d5-e6-f5 pawns and activite his light square bishop.  However  it's too late.   24. Rxe5 Now i'm a pawn up but that is not the main point. The most important thing is black's king position is open and black static pawn centre d5-e6-f5  made his light square bishop passive. 24...Rf7
  25. Qd4 This move  is good enough for a win. Black is in time trouble so i try to confuse her with this move. I threaten to play the deadly open check with 26. Rxe6+ . Fritz 11 however found a much better move which during the game  i thought  is  not possible.  The deadly tactician monster show  25. Bxf5!!  exf5 (25... Rxf5 26. Rxf5 exf5 27. Bf6# Checkmate.) 26. Rxe8+ Rxe8 27. Qd4+ Rg7 28. Bh6 25... Nf6? A mistake in a very difficult position. However any other move will not save the position. For e.g  25... Rg7  26. Bh6 Rxg3 27.Rxe6+ Kg8 28. Rxe8+ Rxe8 29. fxg3 26. Bxf6+ 1-0 

Black resign because it's mate after  26... Rxf6 27.Qxh4+ etc.
