[LooseAggressive]

Tough spot here. I think you would have heard from two pair on the flop because it is a very draw heavy board even with such a low aggression factor. A portion of the time I think you run into your same hand, 78, (his line of waiting for the turn and raising to 3x your bet size I've often encountered as a line "the nuts" takes) or a naked 9. Nines full is also very possible but I discount its likelyhood because the flop was not raised.
