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.
