AK on the button hitting top two pair on the river

BB was 87/6/0.22...originally bought in for 5$ had lost it all and had rebought in for another $5 in 32 hands
utg was 31/0/5.5 over 16 hands
I was running about 31/26/7 over 62 hands which was higher mainly because we were down to four handed for a fair time in this session

What would people do now ?
should I check and see how it shakes out , bet to extract value out of smaller aces and two pairs and if so how much?

i mean...with your stack size betting anything but all in seems kinda pointless, and that is exactly what i would do. you have like 2/3 psb left and you are guaranteed getting called by worse.

The money went all in and was called by both of them.
BB had AJ and UTG had 44.

It was slightly annoying because I'd been reading midas06 post in the digest about spotting sets and saving your stack yesterday and the following stood out .

Pre-flop: (5 players) Hero is Button with A K
UTG folds, CO calls $1.00, Hero raises to $3.50, 2 folds, CO calls $2.50.

Flop:8 K 5 ($9.50, 2 players)
CO bets $4.50, Hero raises to $11.00, CO raises $25.00. Hero folds.
Uncalled bets: $14.00 returned to CO.



Ok, let me break this down a bit. First, the Cut Off limped from an early position, then cold called a 3.5x raise. This in itself doesn't mean much at all, he could have a huge range of hands. Personally, I put him on any mid-range pocket pair , a suited connector, or a couple of paint cards which didn't deserve a raise.

The flop is a rainbow, un-coordinated board, which gives you top pair, top kicker. $$$$$$$$$$, right?

Then the formerly passive CO bets into you. This is where alarm bells should start going off. You do the right thing, being aggressive, and raise up your TPTK.

Villain then 3 bets you. The range of hands which have you beat here (because 9/10 you probably will be) are: 88,55, KK, AA, K8, K5, 85.

Because you are up against a tagg, we can safely rule out them limp/calling K8, K5 and 85. KK is unlikely, because you hold one K, and another is on the board. You may also be able to eliminate AA and KK if you don't think that villain could resist raising every time he got monsters pre flop.

This leaves a set of 8s, or a set of 5s. Both of which you are very, very behind.

Looking again at UTG's betting should I have been suspicious of the set with him leading into me on the flop and turn? The only thing that he didn't do was reraise my turn raise.
Was my turn raise size correct ?

This was also part of the reason for my post on aggression stats , I hadn't been as aggressive on this table as I was on the table later in the night but I'd gone up from 2$ to 3.32 playing fairly aggressively . Did that make my play predictable so that UTG was possibly planning a check raise? I took a break for half hour after this hand to look over the hand again and generally calm myself down a bit before starting again.
I'm glad in a way that Will and zorrito (mighty fine graph you have by the way) were in the all in camp and hadn't said check it down only a fool would go all in here.

Another thing I was wondering was whether faced with an all in from someone raising preflop and on the turn were they "right" to call. Looking over the hand now the river could have made a flush , straight , or higher set but I don't think my betting represented straights or flush draws.
