OK, supposedly the computer analysis feature has a rating of around 2500 for me (platinum membership), but from time to time it's really stupid.
Case in point is this game : http://www.chess.com/home/computer_analysis.html?id=43926410&game_type=1 (I hope at least admins can see the computer analysis as well). My opponent resigned, but if you look at the continuation the computer suggests, it misses a very clear mate - Rd1# in the last move. It looks like it ignores the threat all along, actually.
How is this possible?
new, stronger game analysis almost here!
I have had the same problem with there computer analysis in the past, I just use Deep Rybka 4 when I analyze a game
Ah, thanks Erik. Obvious bugs like missing a mate aside, the analysis could use an overhaul for other reasons too.
To be honest, I tend to only look at blunders these days when investigating the current computer analysis. Inaccuracies very seldom make a difference (also because they are based on the supposed optimal play from each side, which you never see in games below 2000 rating), mistakes can also be quite trivial - it takes a blunder to be absolutely sure you've done something wrong.
So let's hope the new analysis is more helpful.
Okay, it's been 15 months, when will it be here? I just won a game where my opponent resigned when he saw that mate was inevitable. http://www.chess.com/echess/game.html?id=54280668
The computer analysis scores the final position as Mate09. However, it also scores my final move (Qd6+) as a Blunder!! Instead, it says the best move was Qb1, and offers a line of 12 moves that don't get to mate.
How can that be? Can anyone explain?
I had the same problem 2 weeks ago, you can see the faulty analysis here: http://www.chess.com/forum/view/game-analysis/what-am-i-missing
Don't get me wrong, even faulty analysis is better than nothing, I had a mate in 2 that I missed, and the computer pointed out to me. (The queen was just too tempting!) But this is one of the perks I'm paying for as a premium member. It's promoted on the membership page as "Our super-computers analyze your game and give you a fully-annotated report! Grandmaster-level computer game analysis!"
I don't feel that's what I'm getting.
The engine is useless. The engine tell me, that Kxf5 is a blunder, it would move Kg7.
I made a similar Post in "Help & Support" some 5 days ago...still waiting for an answer.
I had an alysis done today where it said I mad a mistake and I should have moved my queen so it could be captured with no compensation, after which the other guy had a decisive advantage, where as the move I chose had a moderate advantage for the other player.
