Somehow I managed to get the pgn in file into Shredder (why Shredder?) It was very confusing. I thought there would be a voice (from Heaven perhaps) that would say, "stwils, your move to B6 was terrible because..." No voice. No real help unless I learn to decipher Shredder.
Right now I do not see how on earth this is going to help me play chess. Perhaps my time would be better spent with the Tactics Trainer or "Play Winning Chess."
Disappointedly,

You should be able to go to any game you have on chess.com, finished or in progress and click on the moves tab. There you should see a link below the moves that says get PGN. click that and the browser should save a file to your computer. Go into whichever program and open the file from wherever it was saved.
As pointed out though, using a computer to analyze a game should only come after you yourself have sat down and analyzed the game. That is where the improvement comes from that is talked about in books and elsewhere. It improves your calculating and visualization abilities, plus helps you identify weaknesses that you need to work on. The computer can then tell you things that you missed, especially in the tactical realm.
