DS got Chess Tactics for Beginners for Xmas. What I will say about this CD-ROM is that it is not nearly as engaging for children as Fritz and Chesster, which would only make sense as it is not specifically designed for children, despite goofy cover graphics. However, I can tell that it will keep DS busy for a long time, and that it is powerful and versatile, so I'd recommend it for kids who are already interested in chess and looking to up their game. So far DS is not finding it very hard, but I think that's because it starts you off easy and works up. However, it is recommended for kids with ratings under 1400-1500 so keep that in mind.
