We know that, a good 3 bet size(hypothetize we are IP,like on the button) requires us to not bet small so that we give our opponent good pot odds to outplay us and not too big so it chase away all our opponent.But if many players sitll not in action,like the MWP,it's a little bit complex for us to design the right size according to the principle as we mentioned before.So,if you MUST have to decide whether to 3bet small or large,which line would you choose?
