Do I bet this flop with KK or just call? Or fold lol

[ThaHero]

Well I wisely checked, then lost my senses...

One guy bets the pot, about 15$. Guy in front calls. I consider my odds, thought it was maybe 3-1 or so, and just pushed for my remaining 1.75. Both call.

K comes on the river and saves my arse. Both players check it on the end.

One Villain shows 10 [img]/images/graemlins/club.gif[/img]6 [img]/images/graemlins/club.gif[/img]. The other shows A [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/heart.gif[/img]. I take down the pot but wondering if my call on the end was correct given the pot odds or should I have just folded?

The pot was $20 on the turn. He bet $15, the other guy called $15, so it's now $50. I have $16.75 left. A little over 3-1. Am I good(or do I get good) 3 times out of one here, based on the action?
