If everybody was full stacked, that's probably a call at least for set mining odds
With BB only $13 deep, calling sucks because it's somewhat likely BB shoves any flop and we kind of have to call unless it comes AKQ, but we still have no clue what BTN has and we could get pot committed with a very marginal hand.
So I probably fold here. Maybe not a huge EV difference, but much lower variance. Also, it's quite likely we get to see a showdown between BTN and BB, so we'll get valuable info even when we fold.
