if you are folding this flop after calling the 3bet then just fold it pre. as played i think you need to check /call this flop and evaluate the play on the turn. you already know he is not AQ or AJ or AT hearts, and you know there are not many combinations of hands with a K in them available, especially since Kx hands will check back here often.

if he has JJ-TT etc you still have plenty of outs and check/calling the flop with a king is perfectly a reasonable play and you seem to be the nittiest player of all time so having a king in range is possible, too. if he has AJ AT, etc, you are ahead, anyway

i would have been more scared to see a single king on the flop. the question is, if the flop had been A x x, how would you have approached it? because if he is raising TT+ and AK, but not AQ AJ AT KQ and 99-?? then this should always be a fold. if he is raising a little wider then this isn't exactly a scary flop

Haha. I wouldn't call myself nitty (maybe im delusional), it just looks like that because those hands are the only one I post. But maybe, but the point is that in NL2 you can't think about ranges and/or bluff as easy (my experience is that bluffs outside of cbets are fail whale) since people play straight up a ton so I just have to adapt if that makes sense. In this case I think 75% of the time I will call flop, then some shitty low card will come on the turn, he will cbet turn and I will have to fold (or at least thats what I thought back then)

I don't understand the last comment, if flop would have been A x x I would have been more comfortable (any pocket pairs except AA which is heavily blocked would be worse than my hand, only think leading then is AK). Here AK as well as KK and the possibilities of him playing KQ KJ KT is there (slim, but still) which is scary.

I understand your point with one king on the flop would be scarier (Do I call this bet on the flop if flop was K 9 3?), I just feel in general hopeless when I don't hit flop (and there is a big card like K that i miss) because calling turn/river is just throwing money away when cbets come. I'm not defending my play at all but thanks for the comment it made me think about flops like these.

But just so I understand you correctly: You are saying that since 2 kings showed up it is not high probability that he has a K and when he cbets the flop it is easy to call and represent a king to make him not cbet turn and then win the hand. And in case he has TT/JJ and doesn't respect my hand I have outs for Aces or Queens on turn/river (as well as possible flush). Is this the case?

Also what do you think about calling 3bets (or 3betting) with AQ in general?
