I am not aware of any that will score a total game, but any decent program will score the moves with an automated analysis mode and post the suggested variation.
I suggest you check out scidvspc. It will do automated analysis of entire databases, so you can let it scan all of your games overnight.
Another option is a program called LucasChess. I can do this a well and also create a training module to present the positions back to you like the Tactics Trainer here.
Honestly you should try both. They are open source so the only thing it will cost you is your time.
I'm looking for a computer program which will analyse my games and give them some kind of score - perhaps like the Chess.Com gives a summary of Inaccuracies, blunder, etc.
Anyone know of such a beast?
