Computer analisys Recently I analysed a past game of mine with a chess-engine. I was able to compare the opinions of the impartial silicon move-cruncher with my own. It's a game I already analysed in depth, and even posted here on GK. In several critical points, the computer came to a completely different conclusions than myself, in some cases he spotted truly spectacular refutations. Hope you'll enjoy reading this ... First, the raw move-list:

White: A. Greenfeld
Black: Yours Truly
Regional team championship, round 3
Time control: Game in 2 hrs
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6
6.Bg5 e6 7.f4 Qb6 8.Qd2 Qxb2 9.Rb1 Qa3 10.Bxf6
gxf6 11.Be2 Nc6 12.Rb3 Qa5 13.Nxc6 bxc6 14.0-0
d5 15.exd5 cxd5 16.Qd3 Bd7 17.Rfb1 Bd6 18.Qf3 Ke7
19.Bd3 Rac8 20.Ne2 Rcb8 21.Nc1 Rxb3 22.axb3 Qe1+
23.Qf1 Qxf1+ 24.Kxf1 Bxf4 25.Bxa6 Ra8 26.Bd3 Bxh2
27.Ne2 Be5 28.Kf1 Ra1 29.Rxa1 Bxa1 30.c3 f5 31.b4
e5 32.Ke2 f4 33.Kd3 h5 34.Kc2 h4 35.Kb1 e4 36.Bxe4
fxe4 37.Kxa1 f3 38.gxf3 exf3 0-1

Some interesting points revealed in computerized
analisys:

1. My comment to white's 16th move was:
"A simple, but very strong move, preventing black's
intention to exchange queens with d5-d4."

The impassionate computer however spots the much
better 16.f5. What happens if black plays the
planned d4, you ask? Well, after 16.f5 d4 17.Qxd4!!
Bc5 (should white resign? No, not quite...) 18.Bb5+!
white is better ... so in truth 16.Qd3 wasn't so
good after all!

2. My comment to black's 19th move was:
"Much better than 19...Rab8 20.Rxb8 Rxb8 21.Rxb8 Bxb8
22.Bxh7 and white should be able to draw this (eg.
22...Bxf4 23.Nxd5+ Qxd5 24.Qxf4 Qxa2 25.Qb4+)"

The computer however is quick to spot an improvement:
19...Rab8 20.Rxb8 Rxb8 21.Rxb8 Bxb8 22.Bxh7? (better
not to take this pawn, remaining a pawn down) and
now comes the impressive 22...Kf8!! - and suddenly
the white bishop has no good retreat (23.Bd3?? Qxc3)
and black is threatening Kf8-g7xh7. The computer
gives around +2.00 to black after Kf8 (only +1.00
if white doesn't capture h7 though).
So the truth is that 19...Rac8 and 19...Rab8 are
equivalent and both lead to a black advantage.

3. I had no comment on black's 33rd move. The
comp marks this move as in inaccuracy, noting the
much better 33...f4 34.Kc2 Bg4 with a decisive
advantage for black.

Interesting I play a lot of blitz games and I always run these through an engine afterwards to see if I missed anything during the game and also to annotate them whilst they are still fresh in my mind.

I am always striving for the "perfect" blitz game but usually find that I made a weak move somewhere or, on occasions, both my opponent and I completely missed a brilliant (or just plain obvious !) move !!

Kind regards,

Cal

Try ChessBase Lite It is a free program and once you have downloaded it you can drop your game pgn straight into it. It is useful for highlighting blunders or lost opportunities and I routinely replay and check all my blitz games on it. It uses Fritz 4 which is hardly state of the art technology but certainly good enough for checking blitz games.

Kind regards,

Cal

Yes, chessbase lite is what I am using. Probably the best chess freeware you can get. You can download it from www.chessbase.com
