I like flop call because there are lots of value hands like 2pr+ or even a spewy 1 pr+straight draw that he could decide to get and our equity as great as we would like. Better to call, keep fish in and use our position.
I dont like turn bluff unless you plan to make the one pr + draw hands fold with a river bluff on the higher river cards that don't complete the draws / 2 pairs, i.e. any T+ river, and maybe a 2. You say he has lots of 1pr+draw type hands, and I agree, and you rightly say you probably have no fold equity, but it's 2-street fold-equity you should be considering.
In this particular spot I think a turn check-back is best, as we may get blown off our hand, its 3-way so more likely to see a monster and fish may well call turn and river with just one pair.
In general there are many spots that could arise on the turn where the turn bluff alone is not +EV, but when factored in with a river bluff, the 2-street play becomes +EV.
Definately value bet river. Bet something that may get looked up by a 1 pair hand, so around half pot, or even slightly under. He mostly folds but those times you make as much as if you had checked back anyway. You get far more calls by 1pr type hands than you get CR'd imo. It's also very good for our balance. The turn bet was only good if we bluff river on the high cards, so we have to bet for value also. That way we merge our river betting range to include thinner hands like this aswell as bluffs and nuts. Makes you very difficult to play against!
