1997}) 12... Qa5 {Black starts to be too clever already. The queen was too
exposed in the centre so a invested a tempo to get the queen secured. But now
was the time to be ruthless and find the best plan} (12... Nd5 {Moving the
knight again to force more exchanges is the cleanest way to win. I saw this
but did not like the idea of moving the good defender again} 13. Bd2 Qxe2+ 14.

careful of potential compensation to consolidate the pawn+} Qc7 {
The tempo and pawn eating queen returns home and hides behing the protective
pawns. The overall play is to finish development and start pushing the
kingside majority} (13... Nd5 14. Bd2 Qc7) 14. Bg5 {The Bxf6 threat must
be taken seriously} Nd5 (14... Ne8) 15. Qh5 {This sortie fails
completely and just loses time} (15. Rad1) 15... f5 {Closing down the /
^b1-h7 attack diagonal kills any attacking hopes} 16. Ne2 e5 {The next step is
to keep advancing with the idea of restricting the enemy minor pieces} 17. Rad1
Be6 18. Rfe1 Rae8 {Completing development without any problems is a good sign}
(18... a6) 19. Bc2 Kh8 {Useful prophylaxis} (19... h6 {A couple of pawn
moves would now consolidate quite easily but now Black gets careless and loses
thread of the game} 20. Bc1 b5) 20. Qh4 {Black needs to find a good plan
here to consolidate the P+} e4 (20... h6 21. Bd2 b5 {Securing Nd5 is
strong}) 21. Nd4 Bg8 {The bishop reinforces the kingside and clears the
e<-> for Re8 to support the e-pawn. Things are again looking quite good} 22. a3

off is best but there was more than one way to win} 24. Qxh2 Qxh2+ 25. Kxh2

a convincing plan} (24... Qe7 {Transferring the queen to the kingside was a
good plan} 25. f3 Qf6) 25. Qe3 a6 {Preparing ..c5 but this was really a
passing move as still I had trouble finding a good plan} (25... Be5) 26.
Bb3 Bg6 {Wriggling up the board was an interesting concept with the idea of
..Bh5 completely disrupting White's pieces} (26... c5 {This was possible and
would completely smother White} 27. Ne2 Nd3 28. f4 c4 29. Ba4 b5 30. Bc2 Bg6

I thought this was crushing but it was not the best at all. Taking the g-pawn
was best} (28... Bxg4) (28... fxg4 29. Bxe4 (29. Kh1 Nh3 30. Rf1 c5 31. Ne2

has to deal with} f2 {The machine agrees this is best. Black tosses in a
couple of mate threats to turn up the heat} (35... cxd5 {Was what White was
hoping for} 36. Re7+ Kh8 37. Rxc7 Bxc7 38. Ne3 {An ugly turn of events}) (
