overcalls on the turn ???

[Little_blue]

Playing a looose 3-6 game in AC.
Players are all loose and for the most part passivie averaging 5 to 6 plalyers perflop and one pot is rasied ever 20 hands or so (unless I'm raising).

I'm on the button with 66.

4 players limp, I limp and the blinds complete.

7 players 7 sb
Flop
K Q 7 rainbow.

everyone k including me.

3 big bets to the turn.
Turn is a 6 putting 2 hearts on the boared
K Q 7 6 (with 2 hearts)
everyone checks to the cut off who bets. Now do I rais my trips and protect this kind of large pot (at least it was on the flop???) or do I check and go for overcalls with a bit of a monster hand.

I just called and every one else called (got to love it).

River has 7 players and 10 BB.

River is a T
K Q 7 6 T

everyone K to the CO who again bets, Here I think its easier as I go for the over calls and just call (beginnning to fear the AJ or 89.

Any comments apreaciated. thanks.
