As a basic member, the chess.com computer analysis is not very good, since the depth of search is very limited to 8 ply (estimated 2000 strength).
Here is something from help that explains a little of the strength:
Computer Analysis is an instructive feature that gives you an "expert opinion" on games you've played at Chess.com. See where you (or your opponent) missed opportunities, and give yourself a chance to really learn from your mistakes!
Simply view any completed game: Live Chess or Online Chess (but not 960 games). From here, you can click on the "Computer Analysis" link to the right of the board and above the Chat Window/Move List. This will submit the game for analysis by our chess engines.
Because the analysis is quite deep and the resources are shared by all Chess.com members, this process can take up to 24 hours to complete. You will get a message when it is finished and you can view your results.
The Computer Analysis feature has different access levels depending on your membership at Chess.com:
- Basic/Free: 1 Computer Analysis per week - with a search depth of 8 ply (estimated at 2000 strength)
- Gold: 2 Computer Analysis per week - with a search depth of 10 ply (estimated at 2200 strength)
- Platinum: 25 Computer Analysis per week - with a search depth of 14 ply (estimated at 2500 strength)
- Diamond: 100 Computer Analysis per week - with a search depth of 14 ply (estimated at 2500 strength)
the computer analysis is giving "'?"" when i played sicilian defense. i am confused? just 3rd or 4th move, it is asking ?.
in computer analysis anticipated move(or in expected move list) it is moving the king so i cant castle the king anymore if i follow those steps. very strange! castling the king is expected move.
so is it really good? i am new here. i play in gameknot and their analysis seems so good. but those who are expereinced can tell me how good chess,com is.
