I dont understand why people are saying that we cant call PF we're well within the 5/10 rule for set mining or we can try and play well post flop.

I dont like the argument for 4- bet shoving here unless we're doing it as a bluff. I don't really see what hands a 20/17 is 3 betting here and folding to a 4-bet shove that's going to call a regular 4-bet. and 4 bet shoving with small PP's and small aces and then 4 betting for value with AK+ is goin to get found out pretty quickly, IMO.

as to original quesiton i think its a call and let him barrel, catch up, etc. Only problem is if he's got a hand like QQ and a A or K hits the turn and he slows down.
