Lets say this is 200NL. Opponent is a thinking reg and overall a solid player. No datamine so your stuck with only w/e stats you have on him from this session. You have 3betted him a few times both IP and OOP and he has folded all of them (say 4-5 times within). You have A3 sooted and 3bet ($28) his LP raise and he 4bets you to say $70. What do you do?

The first time I 4bet a habitual 3bettor, I am almost always bluffing. Now isnt there a good chance he might be doing it as well? This is ofcourse against certain oppenents. If its a villain whos been flatting 3bets too much n suddenly 4bets or a really bad player or a nit, I would insta muck. But against the kinda oppenents I described, wouldn't a 5bet shove be more profitable?

Let's say half the time he is bluffing, and half the time he has it.

Put into pokerstove.....:
equity win tie
Hand 0: 29.929% 28.91% 01.02% { As3s }
Hand 1: 70.071% 69.05% 01.02% { JJ+, AKs, AKo }

The half he is bluffing, u pick up 35X BB. And the other half you pick up 30X BB. You lose 70/2 = 35X BB so shoving here gains u a profit of 30X BB right? Curious what you guys do when someone like that 4bets u for the first time.

Any comments or suggestion is appreciated.
