Let me just say what the answer I think really matters here is and what it says about how we should adjust to other players.

The ostensible right answer on what to do vs A and B is to open 100% otb. After the 3bet part I think there were some good points but all I really cared about is not folding.The answer could also involve a mix of limping, which actually could be better. What the correct answer could never be is folding the button more than 0% of the time.

While people 3betting you 24% of the time may seem like a lot, with each player folding 76% of the time to an open make every single open +EV (It actually helped me a lot to realize that in this same scenario if you make the 3betting frequency 25% it makes every open where you are not calling or raising a 3bet -EV, which is going to make your opening frequency much lower). Despite the fact that us tightening our button opening range makes their strategies more of a mistake, it doesn't make tightening our button more optimal.
