i'd fold pf.

i'm not sure about the best flop play, i can't decide between all three.

but if you raise the flop and he just calls you have to check behind on the turn. you'll induce a river bluff from a hand like 99 that might have folded to a turn bet, you'll avoid the inevitable turn c/r from the hands that have you crushed, and you'll be able to see another card for free (not really an issue now that an A fell, but it could be nice on some other boards).

since you bet the turn, you have to fold to the c/r. you are boned.
