3/6 live: K high 1 card flush

[deagle185]

This is one of the hands I played at Turning Stone yesterday. The players were generally loose/passive.

I'm in the BB w/ K [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/spade.gif[/img]
Preflop: 4 limpers from mid and late position, SB completes, and I check

Flop: J53 [img]/images/graemlins/diamond.gif[/img]
I check. First limper bets and two call. I call (should I have folded?)

Turn: 6 [img]/images/graemlins/diamond.gif[/img]
I check, first limper bets, one fold, and last position raises. Easy fold with 2nd best one card flush considering players are generally passive and my hand is not that good?
