I hope there is not any at this point, because the existence of one would be a direct infringement on my patent! If anyone knows of one, please let me know.

Just to let everyone know, I am building a graphical user interface that will not only replay games, but act as a database as well. That is, as you enter moves, it will build a list of games where the same position occurred, and you can automatically naviagate through the games to see how others played your opening.

Thanks to Windows XP being such a boondoggle, this thing is nowhere near being ready for release yet, but look for it this summer.
