checking this river would be way more criminal than not betting the flop.

so first of all, given the history between you and villain, bet the flop. bet half pot, like 400 or so if you think there is a good chance he will play back at you. then use position to stack.

given the way the hand played out, either shove the river if he is capable of making big calls, or bet 4000 or something... not betting here is insane.
