It's the cat's meow: Fritz 12.
If there is any better mental training, or any better test of training and intellect than Chess, I don't know what it is.
(Other than real life, of course. Mastering the vicissitudes, raw deals, unfairnesses, subtleties, luck, and challenges of real life is the real test. Of course, dealing one's own personal limitations is a big part of that game.)
A friend of mine with three young kids recently banned all electronic and computer games from the house. "Enough stupid crap in this house." He announced that they would henceforth play Checkers, Chess, Backgammon, Poker, Mille Bournes, Euchre, or Hearts in the house - and that he would give each kid one game every night.
He's been working on Fritz though, to make sure he can stay ahead of them, and his eldest (9 years old) requested a Chess tutor. But even Fritz is banned for the kids. "I want them to play a real human, to learn to read them and their game."
Maybe America isn't hopeless.
