Thoughts on this game, please I played the below recently in a U145 ECF (~U1800 FIDE) rapidplay, and would appreciate your thoughts. There are obviously lots of tactical errors, and please be kind on the last few moves which were played in a desperate time scramble by both sides, made worse by prize money almost certainly hanging on the game, but any constructive comments would be appreciated. The 1-0 result is because black tried Nxa3+ at the end missing the check from the white queen, and so losing on the illegal move rule,

All that I have analysed from the above game are enlisted below. I don't know which side @Ian Bush was on, so I am making suggestions for both sides. Hope it helps. Here it goes:

FOR WHITE


White had a slight positional disadvantage in the game as early as move no.7 since by this time, Black had castled, king is in safety, king-side pieces well developed, but White had a centred exposed king, queen-side pieces developed before king-side pieces (against golden rule), center pawns e4,d4 not supported by any pawn.
White should have played 3. c4 which is more mainstream and allows White an early control of the centre which can add to his advantage in the middlegame.

o-o-o is not a good move because of the fianchetto bishop on g7 and also the centre is very dynamic. So white loses the opportunity to attack on the kingside early as Black has the option to blow up the center and rupture the attack.


Bf4 is dubious. Better is 16. Nf5 which attacks the g7 bishop and occupies much space on the king-side and if it is captured by the bishop, pawn recaptures and the kingside attack is easier for White now. 


Bg4 is better and is followed with the idea of Rd5..h5..h6 which tries to mend the position.


f3 might have been replaced by 31. Qd6 followed by 31. .. Kg8 32. Bf3 going for a fightback.


Qh8# could have sealed the game however.



FOR BLACK



.. Ng4 seems premature. Developing Queenside pieces might have been better.


.. Qf6 would have been better, aiming for 31. .. Bg4 and 32. .. Rd8.


.. Kg7 is a blunder. 35. .. Rd8 is quite stable.


.. Nd4 was the best move.



Otherwise Black had a good game and the final position was almost equal , a little in favour of Black. However the game could go anyway because of White's passed pawns.
