Good raise preflop. I like the raise on the flop aswell, showing strenght preflop and postflop will tell us alot of his hand. He checks the turn so either he has a Q being scared of an overpair or he too have an J or is on a draw of some kind. His check on the river screams "I have no Q" so I bet it here expecting to be called by a worse J or in worst case, KJ.
