i dont know the villian all that much but he was playing well 3beting a lot i had 4bet him a ton also and he had folded everytime he was obviously tilted by me but he seemed okay to just let me win pots and focuses on the fish. I had won no pots of him that were large or significant
Given this, I really find it hard to believe he's 3betting Axs (besides AQs) here very often against you. If it seems he'd rather avoid you and play against fish, he's not going to take a playable hand like Axs and risk getting 4bet off of it or having to call and play an inflated pot (but still pretty deep) OOP.
Any chance you think he's capable of turning AsAx into a bluff, knowing you can't have the nuts?
