Hero

FWIW, I noticed that the timing of his bets were really quick on both the turn and the river, which I thought was kind of odd. Usually if someone has a FD they will at least consider checking back the turn, and usually if someone doesn't have a flush on the river they won't normally instabet.

Are the flop and turn standard calls against this guy?
