Lots of outs + position on the turn with 2 loose players

[Fnord]

3 limpers, I raise K [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/diamond.gif[/img], limpers + BB call.

Flop is JT8 rainbow with a single diamond.

Checked to me and I bet for value. 2 callers. One is really loose/passive the other is someone goofing around with lots of random aggression, floating, etc.

Turn is a non-diamond air-ball. Checked to me and I check behind.

River pairs the turn, loose/passive checks, goofing quickly bets, I cry and fold...
