I have no real reads, but none of the villains seemed particularly out of order so far.

I have KJo in MP3. UTG limps, folded to me, I raise, both blinds and UTG call. Flop is AK5 rainbow, checked to me, I bet. All call. Turn is 2, completing the rainbow. Checked to me, what to do?

Crap, edited to say this is .5/1 at Titan poker. Its a pretty small site, has 2 games going at this limit, mainly regulars playing.
