I guess the bit that made me twitch was the "great poker players do X". It's true, great poker players do indeed go all in to demonstrate, amongst other things, commitment to a hand (well, ish. Actually it's more to reduce the value of the pot for other players. Amongst other reasons. Sort of.) - but so do good poker players, average poker players, and crap poker players who've read about 2/3 of a short book on no limit (the latter would be me). Given that the point of the statement was to compare how Mark Pinkus could be great, rather than average or crap, that rather undermines the whole rhetorical point.
