I've downloaded babaschess (babaschess.com?  or something like that) which comes with an engine called crafty, and then I've downloaded some free engines, a version of rybbka, fruit, gambitfruit.  You can configure babaschess to work with these and then you'll have a pull down menu where you can have it used one of the engines to analyze and make suggested responses to moves.  I don't know if they will do a whole game.  Sometimes they differ in their recommendations.  Sometimes the more time you give them they'll change their recommendations.

I just downloaded SCID but haven't had time to figure it out yet.
