I had been watching the table (and you couldn't find a more passive bunch), but I just sat down with no relevant notes. I had seen several of the players before, with 150 hands on MP1, 25 each on UTG &amp; BT, and zero on MP2.
UTG: 100/0/0.6 (No, that's not a typo, that's ATC.)
MP1: 25/0/0.23 (Likes Axs, saw AKs no PFR called UI to SD]
MP2: ??/?/?.??
BT: 48/0/0.33

So it's 12BB to me with one still to act and two to react. The only thing that can beat me is precisely KT and that is in everybody's range, but I can also split the pot. I'm inclined to 3-bet but maybe this is a better time to try for overcalls. If I raise the only one likely to cap is MP2.
