i check turn here a lot against these types with an overpair and all the 20/10's out there cos they like to call this flop when their pocket pair looks good, and then fold turn if i bet again, so i bet my air almost always here too, they don't pick up on it because they don't call and they don't learn anyway. even with JTs or somethin they take time and fold fearing the worst. like op says, there isn't 3 streets of value here often against this guy, and he rarely calls turn without a good hand, so you get an extra bet on the river often.

i hate the raise though, would it not be better against a more aggressive type?
