What do I do with my old score sheets?
Enter the games on the computer and do something with them, like find other games with the same opening, or get a computer to suggest better moves. In Windows XP, you can do all that for free using Fritz 5.32.

* Chess-playing software comes in two parts, an 'engine' that does the thinking, and a 'front end' or GUI which allows you to see the moves on a board. Sometimes you can get one GUI to work with several engines. So, Stockfish is an engine, and Droidfish is a GUI that works with Stockfish, and you download the two together when you install it.
Have the computer analyze your game and make suggestions:

P.S. I know about SCID and Rybka but there are some copyright and plagiarism issues with both programmes, as far as I understand it.
