UTG checks, Hero???

is there a difference between how he plays AK and QQ or JJ? i wouldnt even call the 4bet, afterall he is utg and would feel your much more likely dominated. that said id fold the flop, you showed a lot of strength by calling his 4bet preflop as small as it is.

Check it back, fold if he bets again.

Fold to 4 bet or call and play JJ for set. As played, check turn, fold river... I really don't understand why u call flop...

Yea JJ just gets you into so many problems here...

I assume you weren't playing it for value otherwise you shoulda shoved the flop...

he did like min 4 bet you pf from utg... Unless you have some info on him that says he likes to do this with any pair or AK and even then I probably still check fold...

i fold the flop most times in this situation but since you got here, his check on the turn is super amazing... I can't imagine KK or AA checking here.. and I also can't imagine him worrying that you have AA or KK so it's just really puzzling...

Maybe he's trying to induce, maybe he's got AK and is worried.... It's interesting...

But still check/fold the rest of the way imo

Call preflop. Dont 3bet. His 4betting range is at least QQ+,AK

I dont understand why you called on the flop, and then get worried when he checks to you on the turn.

He has bet into, and you have called, so whats does the villain think you have that would make you flat call on a board of

866

Striaght draw?, thus the 5, would fill a striaght, even though u raised him pre-flop and it would be out of the hand range to justify a re-raise, he most likely has Ace-King, but if does have a bigger pair, then bet the turn to to repersent a straight if he calls C/C the river, because most likely has pocket Kings and unwilling to fold.
