I have AK overs, so I figure, according to SSHE, that I have only 3 effective outs. I'm facing a pot of 7.5BB, with ~15:1 pot odds. Even if I increase my outs to 5 outs, I need pot odds of 8.2:1, which is still inadequate. Do I call here, and will it be +EV? I'm unsure in this case cos there's a player who's already all-in. Range of BB is wide, he could be holding a small pair, or just caught a piece of the flop.
