Championship Chess is everything a computer chess game should be. With 50 levels of play, this product is suitable for everyone. And unlike some other products, this CD-ROM has independent level and time controls. (In fact, there are six different independent time-control modes.) This means that you can play both speed chess and tournament chess against any of 50 different strengths of play. Windows compatible (including XP, Vista, 7, 8 and 10).
