People write that chess has ~ 10^42 board positions. If you read the paper about solving checkers (which you should because it's excellent), they evaluated about sqrt(N) positions, and the final solution took cuberoot(N) board positions. IF that extrapolates to chess, it means that the weak solution would take 10^21 evaluations and 10^14 storage. That's big, but in the realm of feasibility.
