Villain's stats are probably pretty taggy but I suspect he's a bit of a spewtard at times. He 3-bets a pretty standard range (something like 9s + with some air. This hand happened 10 mins before the hand in question:

And he mucked (we don't get to see mucked cards on the site i'm on)

Now on to the hand that I was lost on. I'm just curious if any check back this turn or if b/fold is always best. It seems like his range is pretty narrow here....33 and maybe 10s though i think he repops that pre most of the time. I can't imagine him not raising a draw on the flop though i can see him flatting a set...i dunno i'm lost.
