AQs with K and flush on board on turn, 8 players in hand.

4/8 Live game. Should I have bet the turn? Table was fairly loose passive, except for CO who is a rock, UTG+2 is a fish who will raise with rags to "mix it up", and call the flop with a weak/no draw. SB and UTG are fairly tricky players, both have limped in with monsters PF and raised with hands like JTo in EP. SB is much looser who chased to catch a runner runner straight on me to beat my KK.

Preflop:[As Qs] is dealt to me on the button. Everyone calls except for MP2 who folds. I raise to $8, everyone calls. 9 players to the flop.

Flop comes [Qd Kd 3s] (18SB - 3SB for rake)
Everyone checks to me, I bet, everyone calls but CO who folds.

Turn comes [7d] [Qd Kd 3s] (11.5BB)
With so many players in the hand, a K and a flush draw on the board, I figured I had to be beat. Everyone again checks to me, fearing a check-raise I check behind.

River comes [5c] [7d Qd Kd 3s] (11.5BB)
It's checked to UTG+1 who bets out. It's folded to me, I call, and the rest of the table fold.

Final pot: (13.5BB)
