I am not sure how good or bad it is to 3bet small PP versus CO and BU? I think it is extremly hard to play it profitable if I call 2bet, because CO and BU are not going to pay me off when I hit, and I will have to give up often when I dont hit.

So is it better fold preflop or 3bet? I guess it is ok to 3bet versus opponents who fold > 66% to 3bet, and give up on non A, K high boards, and to fold versus opponents who call a lot 3bet IP.

Is river shove ok? I think he has Ax, so I wanted that my bet looks as bluff, and if he has Ax he should call anyway.
