I don't see too much that he limp/calls with and then calls flop and turn.
With your read of him getting agressive on the turn with a hand I'd say Jx or a pair under the J are the most interesting hands.
Of the limp/callable hands you beat J8, 77, 88 on the river and tie JT. With your read I'm discounting 22/66.
He could very well have [99, JT, J9, J8] 77/88 would still make sense up untill the river. Vs donkish players I don't treat a 1/3 PSB as a protective bet too often.
Given odds I'd call.
Any reads on how he plays his middle pairs?
