personally, i thought it was as obvious as anything that he held AK here. what else would he call an UTG raise with, check the flop in position against two opponents, and then min raise the turn with? AK is just the only hand that makes any sense. there is *no* way he checks the flop, min raises the turn, and then just smooth calls the call/all in from the shoritie other than AK. if he has TT, 77, or QQ, then my play makes no difference, as our stacks will be in on a paired river regardless of how i play it. AQ doesn't even begin to make sense.
I think he puts *me* on AK, maybe
[Kh]. maybe
[Qh], maybe
[Th], maybe even a mid SC of hearts. but with just 360 hands and being a slight loser, i don't see how he doesn't make some sort of river value bet on AK here.
Then again, this is the reason i posted. i'm wondering what other people would do with this hand on the river. but personally, i think AK is the only possible holding for him on this hand.
