PF: I would raise a bit more, but it's probably okay.

Flop: Fine.

Turn: Less than half the pot? Why? This bet gives him odds to draw, and invites him to move you off your hand. Stack sizes are pretty awkward, here, though. Honestly, I'm not really sure what I like on the turn... anybody got a good line? I'm almost leaning toward a check/raise all in. This punishes him for all the mid pairs, draws, and anything else he might float on you with. If he checks turn, check/call river.

River: Board is so draw heavy, I would probably check/call on the river. You say he calls down with marginal hands, so a push is okay too, if he's really calling with a mid PP or JJ.
