its weak to mate in ones
Computer analysis

Cheating at online chess doesn't hurt anybody. At most, it is a waste of time. The cheater doesn't get to think for himself and thus doesn't learn nearly as quickly as if he had to make all his own calculations. The person playing against the cheater just gets to play a more difficult opponent (and, yes, probably lose). But I, for one, do not care a great deal about my online rating. It does serve as some kind of indicator of progress, but this is the internet and it is impossible to know whether somebody is getting help from a computer or not while they're playing. I say don't worry about it, and do your best to become a better chess player the best way you know how.

Personally i find the 2500 computer analysis slightly annoying because it often says a decent enough move in an early closed position is bad, where really it's not
Therefor I'd say weak points of the engine here would be early positional games. However if you want advice on typical positions with many things going on looking for the best move, this will do as nicely as rybka
This question has probably been posted before, but since I couldnt find it, I ask it here, and apologize in advance: how strong is the computer analysis at chess.com? Is it really about 2500 as it says? Does it have any specifik weak points?
Thanks
