It´s very unlikely Villain b/c the flop with a draw oop. First there aren´t many draws in his range, second, he is more likely to shove than to call and x/f the turn.
@OP: Would you raise a flush draw in position on the flop?
sometimes, his large bet size PF makes me more included to just call the Cbet because it looks strong. I think with a set i have to raise flop so that cards do not come that kill both my hand and my action.
I want him to commit with Ak on the turn, hard to say what sizing is best though, smaller is better to induce CR all in with AK for protection. Maybe larger does the same thing though.
