Never feel comfortable disagreeing with vets of this board like BS but i think versus an aggrofish like this guy clearly is then 3betting AJo from SB and calling a 4bet OOP is never a good idea. Post flop i think is okay but if im 3betting AJ OOP it is for FE because anything other than a J high flop isnt great for you.
Vs this fish just flat and let him value own himself IMO.
