Laying down AKo after hitting flop

[EchoOfThunder]

Hi, i'm a new poster to the forum. Been lurking a little while, but i've improved from the posts here, so I figured it was time to make a name and get even more help. I recognize a few of you from the starcraft forum teamliquid, namely izenra. Anyways, onto poker.

$50 NL at partypoker, blinds are .25/.5.

Just sat down at the table, so I didnt have a read on anyone.

Hero: LP (48$)
Villain: UTG (52$)

Hero is dealt A [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/diamond.gif[/img]

UTG calls, folds to hero, hero raises to 2.
Folds to villain, villain calls.

Flop: K [img]/images/graemlins/heart.gif[/img] 4 [img]/images/graemlins/club.gif[/img] 3 [img]/images/graemlins/club.gif[/img]

Villain checks. Hero bets 3. Villain check raises to 7. Hero calls.

Turn: 7 [img]/images/graemlins/diamond.gif[/img]

Villain bets 5, Hero calls.

River: 4 [img]/images/graemlins/spade.gif[/img]

Villain bets 10, Hero ???

Results in white


<font color="white"> Hero calls. Villain turns up A6, Hero wins pot. Although I won the pot, I think folding was the correct play here, mainly because of no read on villain. </font>


On the flop I thought he might have a set. If he had 33 or 44, calling from an early position is plausible. This was mitigated by the river 4, I figured it was less likely he had a set at this point, but I was still unsure. I also thought he might be a weaker player calling with something like KQ and pushing it too hard. Finally, i was afraid of a limper with aces.

I've come across this exact situation 8 times in the past week. I folded it 3 times, called 5 times, won 3, lost once to aces and once to bottom two pair. It's gotten to the point where I'm afraid of calling a check raise with TPTK, but I dont want to be weak and lay it down, especially with AK. How do you guys feel about situations like this where you have no read on an opponent?
