Turn Decision

[worm33]

30-60 Canterbury very good game. Very bad loose aggressive dumb player open limps UTG+2. folded to me and I raise one off the button with QcJs. Decent but very tight and a player who highly respects me 3 bets from the sb and Worst Player In the World calls from the bb. You canterbury guys should know who I'm talking about. Other very bad player calls. I call.
Flop comes 10d 9s 4s. Sb bets out 2 terrible players call and I call. 10 of spades comes on the turn putting 3 spades on the board. Check, Check to bad player who bets? I can see folding calling or raising here...2nd bad player takes a lot of shots in a lot of pots. what to do?
