I have been using this for 3 years and have bought all the latest versions. It is really the best!!!

Well, being 71, I play a lot of Chess! Chessmaster 10th Edition is fantastic and very hard to beat. It has excellent features and through Take 2 the price was very reasonable. If you play chess, you can rate yourself over many games, and learn a lot.
