I haven't given false info on how I play, but I don't worry too much because like ID said, I try to change it up. It took me awhile not to be a bit nervous in CC tourneys (didn't want to look like an idiot), but now I've gotten over it and can just play my game and be confident. BBB: it's funny you started this thread, because I was wondering the same thing!
As far a 'Dook goes, I haven't played with him much, but I remember in one tourney he folded consistently...don't know if he was trying to establish a rep or what, but when he did play or bet he had a hand. BTW, that was a tourney that I took Nick out in...LOL...good 'ol check raise...one of my first CC games.
