It would be also be pretty sick if he was bluffing with 33 or A2 and got there, but those are possibilities as well. I mean, his range is definitely 2 pair+ and bluffs by the river, so is he bluffing 35% of the time here? That's really the only relevant point.

That said, I don't see how he could ever put you on a hand like TPTK. He might be trying to make you fold Tx or 66-99 with a hand like 65s or QJ. Like frosst said... will he ever bluff 3 streets?
