[2handed]

30 percent is very different than 50 percent. And i think this is a fold both because we have another player behind us and the many draws out mean this push could be BB trying to protect his J9xx+. Since many ppl wouldnt cbet naked aces on this flop he might not want to let a free card roll of that kill his hand (if he just has top two more than half the deck is pretty ugly for his hand). Without a read or a better draw I usually let this one go, this spot is almost never significantly profitable (better than 50/50 in your favor) and often you are pretty big dog.
