After couple of folds i get dealt this hand...

Preflop: Hero is BB with K[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/spade.gif[/img].
5 folds</font>, Button calls, SB completes, Hero raises</font>, Button calls, SB folds

Flop: (11 SB) 5[img]/images/graemlins/heart.gif[/img], 6[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/diamond.gif[/img] (2 players)</font>
Hero bets</font>, Button raises, Hero 3-bets, Button calls

I belive i have the best hand, so 3 bet for value...putting villain on top pair,less likely OESD

Turn: (5.50 BB) 8[img]/images/graemlins/heart.gif[/img] (2 players)</font>
Hero bets</font>, Button raises</font>, Hero calls.

I still think i have the best hand, but his raise makes me think he floped set, or 2 pair (should i 3 bet?)

Hero???

So do i still lead out, or do i go for c/c??? (this is my plan)
Or do i bet, and call the raise?
