Hi. Hi. Imagine a situation where I'm on MP or CO and I'm facing openraise. In this situation, it seems to me that the best solution is to play 3bet.
(A situation where we have all aggressive players at the table).

How do I calculate what all hands I should theoretically play?
How do I factor into my calculations the fact that after my 3bet, the players can still 4bet with me?
Thank you in advance
