True, I just tried the computer analysis and it seems quite weak (for a computer). In this position:
The chess.com computer analysis recommended 12.Qa4+ and a long line following (which was winning), but surely a computer should excel in this tactical position and find 12.Bd5+ with forced mate in 7!
Don't know what engine is powering chess.com, but the site admins might want to take a look at Stockfish. It's open-source, free, and very strong (up there with Rybka, see computer chess ratings for 40 moves/40 minutes games). Also plays Chess960.
Just wanted to say thanks for the link to Stockfish. Never knew it existed.
3:It's not accurate. Rybka, rated 3000+, provides much better analysis than Chess.com analysis.
On the other hand, your current chess.com rating is 1875, so the engine's still considerably stronger than you are. And if the extra 500 elo points really matter, you could always just go download any of the strong freeware/open source engines on the market.
