Analyzing your own games

Hi, can anyone point me in the direction of a robust (free would be nice) chess game analyzer where you can input your own games into it (say, using algebraic notation), and it analyzes your play move by move?

Forgive me if this is an obvious or elementary question, I am relatively new to chess and to this website.

Chessmaster is a good one, but it isn't free.  It's not overly expensive though and has a lot more to it than just analysing your games.

Great. Thank you!

Babas Chess, which is the client I use for the Free Internet Chess Server, is free and comes with a game-analysis engine. You can load games into it, and that's what I use.

Chessmaster 9000 download costs $10 from gog.com - but not sure if that 2002 version does what you want...
