215 ( +1 | -1 ) Computer analisysRecently 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:
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.
44 ( +1 | -1 ) InterestingI 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 !!
34 ( +1 | -1 ) Try ChessBase LiteIt 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.
