Do you float with the nut backdoor here given that we also beat some of his bluffs? Would you lean more towards folding given his bet size? Do you expect him to and should he bet AK like this? How does the fact that we're completely unknown and he 4bets my first 3b vs him influence your decision?
I really only have JJ, TT and a bunch of FD like KQhh, KJhh, QJhh, 98hh if that as better continuing hands here so this hand isn't far from the top of my range.
