Fold pre-flop. King-Nothing offsuit is a fold from the small blind with 2 limpers in front. Dominated offsuit hand with no straight or flush possiblity. At best a blind steal/defense hand. Particularly since you had to call 2/3 a small bet.

Flop is a close call because your call closes the action, probably even still a fold given the small pot size. Heck, the more I think about it, the more I hate that call. You have a weak hand unlikely to improve and because the King of Spades is out, you have a tainted out, so you'd be better off drawing to a gutshot.

The chaser had good pot odds to cold call 2 after the turn given the gutshot + flush draws and 2 others contesting the pot. However, the flop call was weak (but still better than yours.) You just can't drive out draws like that in limit.
