Sudoku - exercise for poker players?

[GoSharks]

I would guess that puzzles like Sudoku probably do have some value for poker players. It probably explains why they appeal to people like us in the first place. Logic and reason are at the heart of good poker, at least that's how I see it, and these types of puzzles seem to stimulate the same places in the brain that poker does. Even if they have absolutely no value in developing logic, they're pretty addicting. I often play them online when I'm just burned out on cards but not ready to turn on the TV.
