The most interesting part of this for me was at the very end, where he mentions a trend of chess masters taking up poker instead; has anyone else heard of this?<p>It isn't really explained, except in association with the earlier paragraph comparing the complete-information, brute-force-able game of chess to a game which involves probabilities, bluffing, etc.  This obviously makes it a more interesting problem these days for researchers, but it's the first I've heard of it being a human trend too.  Unless, of course, it's just about the money, which is also hinted at.
