villain is 21/14 over just 15.

ignoring balance, is the flop donk good or bad? i assume we can't profitably C/C? as played, what's our preferred river play?

Hero?

I like your flop donk - looks seriously strong vs a utg open, lots of good turns to barrel. c/c really sucks cause you don't know villain's cbet tendencies, prolly be lost on the turn etc.

I would bet the river smallish, like $4.80 to try and get AJ, TT, 88 type hands to call, and folding to any raises.

But Iz feesh, let's see what the pros say.

I either 3b/f this pre and cbet 100%, or if I flat him I c/f flop.

As played I guess b/f just over half pot. River is as brick as it gets.
