JJ and a rock (50 NL)

[TableTiger1]

Haven't posted in a while, felt like I have been playing good. Would love some input on this hand. Am I betting incorrect amounts on the flop and turn? What about the river call?

Bet a bit larger on the flop.

Check behind on the turn because you're likely wa/wb with it being more likely you're behind.

Fold the river. Why are you calling a raise on the river against a rock? What could you possibly beat that he would raise? Not a boat.
