ExaChess
I'm a chessaholic. It's true. I love the game. That's why I thought, "I need that!" when I saw ExaChess pop up on the Versiontracker radar machine today.
ExaChess comes in a free lite version and an ExaChess Pro version for A$125 (which is roughly about $92 USD depending on how far the dollar has fallen this week). ExaChess Lite is "a version suitable for maintaining a personal games collection" and puts a cap on how many chess games you can have in the database. It also comes with a more limited library than the "400,000 game database and more than 300MB of Ken Thompson's endgame tables for perfect 5-piece endgames" that comes with the pro version. Both versions allow for exporting games to HTML for sharing on the web, which is a very cool gloat-feature that I intend to employ the next time I destroy Jay Savage in a friendly game.
Now, I just need to figure out how to justify spending the money on the pro version of this program...
