Set 888 on the bord AAK, call preflop, unknown enemy

FLOP: Normally his check would indicate he holds pocket pairs, so I think it's a good bluff bet to scare better pocket pairs out of the hand.

Turn: You can't really be bluffing on this spot (It's very likely for you to have an Ace in this situation). So the villain’s raise shows a lot of power and I would definitely would put him back in the Ax range here. I think folding is the best option, because I don't think he would be raising any other combination of Ax other than AK here.. But this is definitely a hard spot and I also want to hear other opinions as well..

Good luck.

Not sure why he would check/raise with KK+ or AK on the black turn, but I think trips is also possible in a spot like this and I would shove the turn for value, but it’s tricky for sure without reads on him.

I agree with SDK1987 - KK and AK are not the only possible combinations and they are only a small part of his range of other Ax hands. And folks at NL2 would frequently slowplay other Ax the same way - he checks OTF because he doesn't know what to do and doesn't want to scare you and he check raises OTT because he wants to win more money with his trips
I don't think we should fold in spots like that unless we have a good read on the villain.

Your perceived range doesn't contain any Ax Kx

I wouldn't exclude Ax hands from his range because he check calls. The board is scary and he doesn't need protection.
I also wouldn't say your range is heavy on Ax hands when you bet there.

He can sometimes have better full house but he also has some trips. I would shove OTT.

When UTG checks a flop like this one you should be very suspicious. (He is reasonably tight and can sure as hell represent hitting that board whatever he holds.) I don't mind the flop stab, and hitting the 5 was unlucky (guessing here he had at least kings fullX(). Not much to do about it. I'd lose my money too, hoping UTG was a fish thinking trip aces no kicker are nuts. Could very well be the case at NL2.

EDIT: I'd never shove turn. It is too rare for him to do this with a draw. What would he have? Q♣:J♣:? No, it is better to let him barrel off. We have position and can bet river if he unexpectedly checks, suddenly realizing A7 isn't the nuts. He'll call with that.

EDIT: On third thought, him checking any river would be very weird indeed, combined with the other plays. I'd actually check back of some curiosity and some fear (to the extent you have fear at NL2:)).

Thank you all for analyse. Enemy showed KK
