JJ Hand. Should I raise the turn?

[Songwind]

No great reads here. The only players I was familiar with from before folded preflop. The table is moderately loose but tighter than the normal random micro table.

Preflop: Hero is Button with J[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/spade.gif[/img]. MP3 posts a blind of $0.05.

I figured I was up against QQ, KK, or AA when UTG+1 capped.

Flop: (19.40 SB) T[img]/images/graemlins/club.gif[/img], 6[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>

Joy. I bet out because I figured either UTG+1 didn't have as big a hand has he advertised before the flop, or he was going to check-raise with a set of kings. Either way, I wouldn't know anything if I checked it past.

Now I figure I'm really a mess with both a K and a Q here, plus the straight draw. No one bet the flush draw on the flop. When UTG+1 checks, I think maybe he's overplaying an ace or something. MP3 was completely unexpected and it rattled me. I thought about raising here, but wasn't sure what it would accomplish so I called.

After MP3's wake-up on the turn after coming along in a capped PF pot, I decided to check it by rather than risk being checkraised.

Final Pot: 15.70 BB

The only streets I'm pretty sure I played correctly are preflop and flop. I'd love to hear any comments on the whole hand.
