Computer Analysis of non chess.com games

Is it possible to do a computer analysis of non chess.com games?
Or would I have to create a second account and play unrated games against it to analyse it :p?

creating a second account is considered cheating and could bring you in serious trouble.
you can import the pgnfile (or replay the game to create a pgn filke) in the freeware program Fritz. It is not as strong as the Fritz you can buy but I am not a GM so it is storng enough for me. Send me a message if you want to know more.

I'd recommend Fritz for doing computer analysis.  The two killer features for me:

1. Evaluation graph:  chart of the numerical position evaluation over all the moves in the game.  very useful to scan a number of games quickly to see in patterns in your games.  Do you tend to be worn down in a positional loss, or were you winning until you blundered a piece?
2. Being able to collect all my blunders into a single database, so I can practice on them and stop making the same mistakes.  This isn't so Fritz-specific, but isn't available on chess.com

Feature request:  evaluation graph for chess.com!

I don't know how fritz works :(.
I have tried the legit version, and I simply do not understand how it works.

I also suggest you use a different program. And I also find Fritz confusing.

I suggest download SCID with a good engine Stockfish (both free downloads), and go from there.

IIf you have any problems getting it to work, message me.

I would also suggest getting a free/freeware/open source product to analyze your games. I utilize SCID and there a number of free engines out there that can provide very good analysis and you can get by with the version of Crafty that is part of the SCID download if you want.
