Anybody reraising the river here? Smelled like a suck bet, with the betting sequence I was certain he made the backdoor flush.

i don't know why you'd even consider reopening the betting without the nuts here. furthermore, not much you beat here is going to call a reraise. you're in the first blind level -- just try to get to the action part of the game with some chips.
