I have an overcard Ace and a BDFD getting 12.5:1. With so many in the hand the Ace is likely counterfeited, but with so many in the hand the BDFD could pay off well. Seems to me as if I have about 3 outs and I'd need 4 to call. This seems like a borderline call which is OK to lay down...but is the pot so large that I should peel?
