I agree with both of the statements you made: You'd expect him to slow play AK and 44, and you'd also expect AQ to bet, but not that big. The fact that you were passive on the turn may lead him to be aggressive, but I don't think that that information is enough to base your decision upon.

You could go both ways here. Either fold, and test him the next hand to see if he takes a very aggressive line when you start being passive, or cringe and call. It depends on how you feel the game flow is going. If the table was wild, reraising all the time, etc, I would call, but if it was a regular table, with relatively strong opponents, I would fold.

Another factor to consider while making your decision is how the result would affect your mental stance. If you know you would get frustrated with yourself if you call and he has it, then I would suggest you fold. By folding, you can avoid anger and frustration, and it will allow you to get more information for when another spot like this comes up.

Based on all of the above, I would fold, but if his bet was smaller (around 2/3 pot), I would lean towards calling because you showed you were scared of the king, which could have triggered him to bluff the turn and the river, thinking you had a medium strength pocket pair. 

Hope this helped! 

I have a problem folding here, but as you said the overbet on the river is indicative of the nuts 99% of the time. I'm always making these type of calls (crying calls) and villain usually has me beat unless I myself have the nuts. I think that not folding when I know I am beat though is one of my leaks.

Here is how my thought process would go: Ooh I flopped trips with a pretty decent kicker given the preflop action (no 3bet from villain). I'm just going to lead right out here and hope villain thinks I don't have an ace. What the...? He raised me? Well maybe my donk bet induced this, and he has a hand such as JJ-55 or a weak ace that's not A4 and he doesn't believe me. I don't want to kill my action from these hands so I "smooth" call. Turn I wouldn't have check/called but just hypothetically if I did I would think "now I'm playing this so tricky he has to be bluffing me trying to get me off my small to medium pp", River: again I probably wouldn't have check/called but if I checked to him and he overbet like this I'm thinking "now that I have played my hand so passively, he probably thinks I'm weak and is bluffing to get me off my weak holding" I call. Villain turns over 44, A4, AK and I say "WP sir"

A couple things...#1 i might consider limping utg with ajo because if u make it 3x then CO or BTN 3 bets to $1 and u decide to call and u get the same flop aax u could have kicker problems. #2 lets say u make it 3x and CO calls which he did the problem with leading out here is that if he goes crazy by raising pot and/or shoves once again u could b facing a decision where ur kicker could b a problem and there r going to b so many more spots in the future for u to outplay people ip that i dont believe u should b bloating the pot w aj oop. but since u decided to double barrel then check the river, ur basically giving up and hes taking advantage of this by over shoving and polarizing his range. its a tough fold here but do u want to call a 2.2X pot river bet hoping he doesnt have aq ak a2 a4 44 22 kk...NO!!!!...like i said it sucks but i feel u put urself into this position...i guarantee if u limp/call pf, c/c flop, then ott if he doesnt have it when u check he will check behind if hes not strong and ull have the opportunity to bet for value oop on the river with the intent of if he raises the river ull have a better understanding of where hes at based on previous hand history....IMO pay attention to position and rather then making decisions based on his actions u take control of the hand...

with no other reads id just fold. I think its pretty clear you have Ax here, and I doubt he ever expects you to fold it, so id fold it. Maybe hes a level higher and thinks youll fold all your aces that arent AK to his massive bet because of what I just said, in which case hed pwn me. But sans history or any other info, I dont think its a suicide bluff from an unknown reg

NoHubris, calling down this hand and loosing influences my mental game a lot, I get frustrated as I promised to myself I will not make crying calls any more. So in this case folding the river is a clear win for me.

Haha Piper exactly my usual thought process. Calling to much is my leak as well and I try to correct it. It is one of the things I pay attention to in my warm up routine. 

Dyson, I am never limping UTG PF. And raising AJ UTG seems like a profitable move and I do it 100% of time. The turn was x/c. The play you suggested might (but I strongly doubt it) work on this flop texture, bu we re going to see so many different flops. Also what is your plan when he raises you PF and you flop nothing? Idea of winning poker is to play agressively and to be agressor in the game not to be left to the mercy of other agressive players.

I'm with toothpaste on this one and I honestly thought it was a fold before I saw the results. I love over betting with a boat here in Vs shoes. Hero is going to have Ax a lot and is going to have to be a disciplined player to lay it down. If it's a bluff I say NH sir, but I don't think it usually is. I think he was probably praying you had an ace and was quite happy when u called his huge over bet. I think unknown V has a boat here almost 100% 

Seems like good logic to me, i fold river :) 

^^ what he said

HI!! 

If it's possible I would like to give my opinion about the hand.

First of all sorry for my english level, cause is the first time that I'm going to write in a foreing language.

About the hand my opinion is: In CO vs UTG with more than 100bbs of effective stack I think that a 22/19 player doesn't have too many slowplays in his range, so I'm sure that hands like KK or AK aren't playing here. On the flop you have a strong hand so I think that just call (like U do) it's the best way to play it, about the hands in his range I think that AK or AQ are not playing here cause they 3bet preflop and 44 is not playing so many times like you think, because he is playing with position the board and he could just call for get one more of yours bets in turn. Turn I think is a good card for you cause all his broadways have right now gutshot (JT, QJ, QT) or second pair(KQ, KJ, KT) and if he hit the K he has showdown value for call you a bet in river, I think check-call here is a great choice. River is a perfect card for your hand, cause all the pockets deuces that he could have are not playing in this way I think, and the backdoor flushdraw missed, check-call could be a great options if you think he has lot of "bananas" in his range, cause he need to bluff for get the hand, but if you think he could have some Kx or pockets like 99 or 88 maybe bet (and think if fold or not if he finally shoves(i think fold is correct cause in nl20 i think most of people are not raising allin with totally air on the river)) is the best way to get more value from her middle hands. following the line you played I call the river for sure, I think all hands with showdown high showdown value aren't overbetting this river :D

GL in the tables!!!

A 22/19 player has a lot of AK combos in his range, given your UTG open.
Unless you have a read on him being a spewmonkey, this is a clear fold, imo.

The only bluffs he can have are like BDSD/BDFD type hands, and your Jc block a bunch of those.
He'd have to raise flop with worse than AJ, and bet-overbet jam for you to win. This is close to never the case, and you're not being exploited here because you'd play AK/A4 the exact same way.

Guljo: I'm with Chael and toothpaste: I think you need to fold.

Chael - do you think AK is calling more than 3b here?

I'd think that a 22/19 would have 3b with AK? At least some of the time? So I'd reduce/remove those from his range. Interestingly, he can't have any A4s - so it's most likely 44, AK, AT-AQ, A2s, and maybe a frisky KK, but most likely a 44 imo.

I also think your hand is reasonably face-up - i think villain would expect you to get it in on the flop with AK; he doesn`t have you on QQ (it`s going away on turn, if not flop); and KK is almost nutted. So given an UTG raise and calling that flop c/r, you probably have something line AT-AQ with a couple of sticky Axs. I think that after the turn call, you're in a "damn, I hope he doesn't bet the river" situation. That said, I'd play the hand the same way you did - with a fold on the river.  I think villain might be shoving b/c he has you on an inelastic range - ie. you're probably calling wide here with bet sizing not being too big of a factor.

Finally, I don`t see any obvious draws that he`d have turned into bluffs. If he`s levelling you here - good for him (fyi, he took a lot of risk bc how many players are folding your hand to this action at NL20). Just note it and exploit it down the road if he keeps getting into bloated pots repping the nuts.

Finally, i hate his line so much that if you had AK (instead of AJ) and the turn brought a T,J or Q (instead of a K), giving you top trips, top Kicker, I'd still fold the river.
