I was thinking of getting Arena and Stockfish (because they're free) and wondered if they can give a post game analysis like chess.coms computer does. I really like that feature but would like maybe a little higher rated analysis, no offense to chess.com, that feature is a great idea! If anyone has either of these programs or rybka, shredder, etc. and could tell me if they can use the program in this way you'll help me with my decision, thanks.

   Also, I'm a complete computer idiot so if you could tell me the difficulty in using these progs, thanks
