Haven't read replies ....

I likely do something different every time before the river, so it'd be a completely different hand for me.

Call pre-flop vs. a player with this description and given these position dynamics (though vs. most live players I've experienced I would be 3betting, but would be 3betting bigger)

As played previously, bet the flop.

As played previously, I'm really leaning toward folding the turn, but I'm not sure.

As played previously, I guess I fold. I haven't played live a whole ton, but I don't know if I've ever seen a river check/raise bluff live that wasn't done by me. I don't really know what he would be check/raise bluffing, but he could conceivably have hands like JJ,TT,88,KQ,AJ (KQ and AJ particularly suited) though maybe they should just mostly bet the river, but he could have them.
