|Jan-28-06|| ||blingice: Larry messed up even games against CM. Move 45 is so stupid for Larry, it's quite obvious to take the ♙, and I don't understand his plan at all. In the Academy in CM 10th Edition, he didn't even explain his plan.|
|Jan-28-06|| ||THE pawn: <it's quite obvious to take the pawn at move 45>|
Yeah, I really can't figure out why he didn't take it. But in the end, the position was already hopeless, here's a line I played against my computer ( I was white ):
45.Rxg4 Rf2 Rf4<Rg1 might be better, the rook could prove useful in a search for a draw> Rxf4 Nxf4 e5 Nd3 Kd5 Kc3 a5 a4 Bh5 Ne1 e4 Ng2 Bf7 Ne3+ Ke5 Nd1 Kf4 <Be6 is appealing here> Nb2 Kf3 Nd1 e3 Nb2 e2 Kd2 Kf2 Nd3+ Kf1 Ne1 Bxb3 and there is really nothing else to do.
|Aug-25-07|| ||realbrob: What a wild, tactical opening... That's not the sort of thing you want to do when you play against an engine. One'd better choose a slower, strategical opening which allows you to use your human intelligence against the computer's brute force.|
Engines often understand nothing of very complicated positions.
|May-02-08|| ||MitchellSri: I have a dumb question. How does black win in this position, since there is no check or mate? Did Christiansen resign at this point or is there some rule I'm forgetting to take into account?|
|May-02-08|| ||tpstar: <MitchellSri> Welcome to the site. =)|
For minor piece endgames, if the superior side is only up by one Pawn, then the opponent can often sacrifice the piece for the Pawn, leaving KB vs K (or KN vs K) which is a known draw. Here Black is two Pawns up, plus the Bishop is superior to the Knight for most endgames, so the win is easy. After 61 ... Kd2 Black controls the Queening square and will keep advancing the e Pawn. White must play 62. Kf2, and then Black plays 62 ... Bc6:

The threat is 63 ... Bxg2 trading down into a won K&P ending. 63. Ne3? & 63. Ne1? are both out due to 63 ... g3+! winning the Knight (63. Ne1? g3+! 64. Kf1 Bb5+), so White only has 63. Nh4. Black can now finish it off with 63 ... Bf3:

Now 64. Nxf3?! gxf3 65. Kxf3 Kd3 66. Kf2 e4 and Black wins, or 64. Nf5 e4 and again White cannot blockade with 65. Ne3? due to 65 ... g3+! winning the Knight. Black will soon Queen one of the Pawns (64. Nf5 e4 65. Kf1 e3 66. Nxe3 Kxe3 67. Kg1 g3 68. Kf1 g2+ 69. Kg1 Ke2 70. Kh2 Kf2 71. Kh3 g1=Q) and mate White's King (72. Kh4 Qg4#).
Test these lines for yourself. See you around.
|May-04-08|| ||MitchellSri: I see how black can go on to win, I just wasn't sure if White resigned or I was overlooking the win in 61...Kd2. There should be universal notation for resigning. That always confuses me. I guess you can just assume if one side won, and it didn't end in checkmate, there was a resignation.|
|Dec-13-08|| ||Bautismo: I once beat Little chess partner, that's my greatest achievement in computer chess...lol|
|Dec-13-08|| ||DarthStapler: I bet this was blitz|
|Dec-13-08|| ||Bautismo: Why do you assume that?|
|Dec-14-08|| ||DarthStapler: Because 99% of games on ICC are blitz|
|Dec-14-08|| ||Alphastar: This was not a blitz game but one of the games in a 4-game match between Chessmaster and Christiansen.|
You can also see it's not a blitz game by the score headline (ICC 2 120 u 2002 ) - indicates that both players had 120 minutes at the start of the game
|Dec-14-08|| ||Bautismo: Yep. Besides, positions seem way accurate and complicated for a 3-5 min game...|
|Jan-01-09|| ||Mikhail Tal fan: my greatest achievement versus computers are only draws vs Chessmaster 11 ( Tal, Leko, Anderssen , Petrossian personalities..)i mess up in positional struggles against Botvinnik and Capablanca personalities..losing in the endgame with pawns and king..i also played once well vs Rybka in chess ok(thought it s not in its full strenght..) i tested this "demo"Rybka vs my full chessmaster (vs Fischer personality)..Chessmaster lost!|
|Jan-04-09|| ||Bautismo: In the game the bad personalities (1600-2000) are so annoying, they start playing more or less perfect all the way, then they make a "stupid" sac, which completely messes up your kings safety and the rest of the game you see yourself trying to survive by exchanging all the material... its so boring and frustrating...|
|Jan-04-09|| ||Interbond: How accurate are these personalities ratings compared to human ELO rating? More accurate than Fritz,Shredder etc rated games? I would guess they are too high.|
I have played a few games (under 10) between Chessmaster 9000 average 2400 (2300-2500)personalities against Shredder 8 rating set to 2400. Chessmaster used a weaker computer, but got a rating about 2600 on Shredder and Shredder about 2100-2200 on CM. I don't remember exactly. Anyway the CM personalities was much stronger.
Now I'am trying Shredder in Friend Mode against 1900-2100 CM personalities. Chessbase says that in Friend Mode the engine will adjust to your level . So I will play a lot of games to see if Shredder in Friend Mode can get a rating between 1900-2100 against CM's personalities.
|Jan-09-09|| ||Bautismo: Actually, some people have posted here in similar threads that the CM rating that one acquires after playing several ranked games, is probably much higher than in real life... I guess that applies as well to the CM personalities... I have also experienced this, since I, a terrible player in real life (don't even have an official rating), have crushed an 1800 rated personality in CM.|
