Villain is running 30/7.6/.29 over 26 (small sample). No good reads since I've yet to see villain show down. Villain check/calls my flop bet so I am suspicious/hesitant to bet the turn and decide to check for pot control and call a reasonable bet by villain on a safe river card since I've been burned lately overplaying top pair hands and am trying to manage this leak. Up to this point I'm considering villain holding a flush draw, Ax or a small PP. When the river pairs and villain pushes my TPGK shrivels up.

Turn: I normally bet again, although most FDs are folding as they have no OC outs either so checking for pot control if fine.

River: Whacky shove, I call, his agression factor mkes it look like a bluff heaps to me

i always bet this turn like 2.5 and fold to push

I bet that turn. If he has a pure FD this is the only street that you can get any more money out of him. River sucks. Sometimes I call, mostly I fold. When I call, I'm usually beat by a set or runnered trips and feel dumb.
