Fold river??

This is tough.
Calling three streets is rarely +EV. On the other hand, this is one of the best hands you call PF with (although I would rather raise it).

Villain has increased bet sizing from F to T, so its not just pushing buttons? Stilll consider raising T?
Close.....
But I am known for spewing......

In my opinion this hand its clearly played poorly, Beginning with preflop this should have been a 3bet hand. Flop should get the bb to check and with top pair and 2 backdoors, straight and nut flush draw we can safely bet here. In this case since you played it passively pre then calling is also fine. Turn gave u a great card to check raise with ( 2ACES +3TENS+ NUT FD) and get most pair hands and weak aces to fold or call and loose against u. You have A blocker against better ACES. You are also blocking flushes and Straights. River imo should also be balance there. You can call sometimes or raise as a bluff since some draws missed and a 5 help no ones given the flow of the and, plus as mentioned before u are blocking the low straight as well. Just my thoughts on how the hand developed. Happy GRINDING!!!

I think overall this hand is played quite well. There are some small things thought.

For example I would 3bet this pre-flop but in my opinion it is not a huge thing. I have seen different ranges from professional players and some would call, some would 3bet and some would play it with a mixed strategy. Snowie would also play this mixed. But as I said, I think 3betting would be the best.

As played, OTF standard call.
OTT calling is fine. I would probably just call as well but I can see some merit in check raising. Checked this with Snowie and it would also call 85% of the time and raise 15% of the time but the EV is the same.

River is interesting. That is actually the main reason why I started checking this with Snowie. Now Snowie would call. We can also think that AT is quite high in our range and because we could also 3bet hands like A2 and A4 and fold those low Q hands pre, we really don't have much to defend with. Villain also didn't bet so big and we need to win only 25% of the time.
But now we are playing NL2 and against an unknown. We should consider that 3 barrels are often quite strong here. We also don't need to think about defending our range against this guy. We could also consider that he increased his sizing slightly OTT which could hint that he is protecting a made hand?

So I think this can go either way. And you have many decent options on many streets. So I don't think there is anything awfully wrong with this hand.

Very interesting hand to analyze. I like it as played and i mix calling ATs with 3betting. I guess its up to the play style.

Snowie recommends that we call the river but there is absolutely no need to be GTO at nl 2. Nobody would exploit you here if you fold. At higher stakes it would be different once they realize that you do not call 3 barrels in a single raised pot on Ace high but at NL 2 folding is fine.

Raising turn is close i guess and i would most probably do it if a have info that villian can fold AK/AJ there. If its unknown i prefer calling as we do not make a better hand fold. Example - at NL10 - nobody would fold AK/AJ there.

River is interesting as villian bets a bit less than 1/2. I think you are beaten a decent amount of the time but at nl10 where i play i would shove this river as a bluff very often (unless i am playing against cs). Reasons:

1. Villians sizing is looking like a block bet type which screams "I have a good hand like top pair good kicker but im not sure if im not beaten by two pair/sets/straights so i bet small and hope to not get raised and be called by a weaker top pair.
2. Villian does not realize that you do not have many 3s in your range besides A3 and he is afraid that you might have a straight although you almost never have a straight here.

At NL2 though - i am folding this river as they might call AK/AJ here out of curiosity and cause its NL2 you know.

I thinks this is wp. Preflop can go both ways. Flop is fine, T I dont see a reason to raise actually. OTR I would fold, maybe in theory it´s a call, but at NL2 zoom I believe in overfolding. You block some bluffs as well.

why do we want to turn this hand into a bluff? sick population exploit?
we're blocking many bluffs and we are targeting what should be a quite strong range (our frequency is also crazy if we bluff this but, in all honesty, nobody really cares). i'm not sure about you, but i prefer to bluff when my opponents are weak, not when they are strong

Pre-flop there's nothing wrong. You have to obviously include ATs in both your calling and 3betting ranges. On NL2 this is irrelevant imo.

The flop favores the agressor and the cbet is standard. You can't fold here, so you're either calling or raising.
Calling is the best option imo.

Very nice turn. I'm raising his bet here. By calling here you have to consider how you're going to play the river if you don't hit your flush. Imo just calling with the intention of folding OTR if he fires the 3rd barrel is very exploitable.
If he calls my raise, I'd do a much more informed fold OTR if he fires or I don't hit it.
If he calls and I hit, I get more chips in the pot.
Therefore, I think raising here in a semi-bluff move is better overall.

Note 1: You're getting roughly 29% pot odds and you have 9 outs (18% equity). Even if you consider an ace would give you the best hand, you have 11 outs (22% equity).

Note 2: I don't understand how you could check-raise here if you're in position against the SB, like some people said above. You're either checking-behind, calling his bet or raising it, but never check-raising. It's just not possible.

I think you're beaten on this river by a better ace. A straight is unlikely imo.
Again, as a lot of you said, calling 3 streets with TP on NL2 is rarely +EV.

In my opinion the hand is well played.I like the pre-flop call,also the call on flop and turn.
Last I agree with your fold on the river,because on NL2 --as a population tendency,not everybody--- if someone bets all 3 streets, he has it,
he has a value Hand.
I think you need AK or 2pair to call here.

I like it as played. We cannot call 3 streets with AT here.
