hero?


Sorry about lack of converter - it didn't work on this hand for some reason.
Hero's table stats were 28/23/7 and I'd been running over everyone. Villians stats were 53/8/2.4
Villian is donkish.

I thought this was a close call between donk taking a stand against me anda flush here. I figured with 2.4 aggro villian raises the flop a lot and he is merely trying to represent the flush on the turn once it gets there. What do you think?
