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.

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.

I like the computer analysis to find checkmates I missed or other tactical opportunities I overlooked. For that, at my playing strength, the chess.com analysis is fine. What I don't like about the chess.com analysis is that it sometimes will indicate a "Best Move" for White when at the end of the analyzed line "Black has a decisive advantage." How does a "Best Move" for White bring about a "decisive advantage" for Black? That makes no sense to me. Does Rybka do that? or Stockfish? So I think either improve the language or improve the analysis. Here is an example of what I'm talking about from a recent game of mine. The "Best Move" for White is indicated at move 40.

"Best Move" in no way indicates that the move is "good" for your game ... it merely states that in a given position, this is best move out of all possible moves. In other words, anything else makes your position "worse" for you.

Perhaps, the language could be changed to "least suckiest move in a  bad situation" when you position is losing.

For example,  a forced mate for White in 5 implies "even with best moves by Black, mate is forced".  Now, if Black plays something less than best, it might become a forced mate in 3.

Hope this helps!
