I play poker practically a year, I am an amateur, but I know how to play against big stacks, maybe this tip can help you. Have a sufficient amount of chips to apply takedown, in final position with a strong range, type: AK, KQ, QJ, AQ, AJ, AT, A9, A8. You can leave Allin without fear of being happy. The purpose and make the opponents fold, more if someone calls, you have the
equity to face any village with that range.
