Go to live chess....then scroll down to where you see your games...then click view....then click computer analysis
How do players on here get the site engine to analyse their games?

You need to go to either your online games history or your live chess games history to find a game you want the analysis done for.
Your online games are shown on the bottom of your current online games page

Your live chess games are shown on the bottom of the page where you go to enter live chess.

Click "view" next to the game you want analysis done on, then the game opens. Look to the right, above the small notations box and it says "Games Analysis". Click on that.
Once it says "processing" you can then leave that page. Once the games analysis is done, it will be sent to your inbox emails.

What about games I havent played on here? Like tournament games. Can I just input the moves and have it analyse at the end?

There you go Damon problem solved, all you had to do was find someone to play unrated with and go through the moves then send it for analysis.

But I actually wanted to submit my real tournament games. I just started playing otb tournaments again last week (one game each wednsday) and wanted to submit them.

Damon, I hope I can be of some use here. I have Fritz 13 analyze all of my games but there are dozens of free software products out there that will analyze them for you. There is even an online one outside of chess.com that will allow you to paste your moves in.

Check it out. You can also search for Arena and download Houdini 1.5 which is free and the strongest free engine. It plays at around 2800 level so it should be good power! If I can help in any other way, let me know!
Hi. I've read some posts here about players getting their games analysed by the sites engine to see how many errors they made during a game. How do I do the same?
