the 3-bet is always the 'bet pot' button by this opp. however much that makes it; pot is at 3.25 before opp acts.
if I 4-bet and he flat calls, I clearly have to lead any flop, but opp surely must know this.
Although if he pushes over pf I have to fold as that really narrows his range. but at least I save approx. 1/2 a stack.
