PLO8 MTT small stakes - interesting hand?

[registrar]

So I find myself playing PLO8 in a Crypto $5 MTT and we're on the money (3 pay) with 5 left. Most of my opponents haven't appeared to even understand the rules but I've just lost my chiplead to a massive suckout.

Apart from me, no one raises pf ever unless they have a starting hand outlined in Play Poker Like the Pros.

Three limps and I have K [img]/images/graemlins/diamond.gif[/img]Kx4x4x in BB and see a flop of K [img]/images/graemlins/spade.gif[/img]J [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/diamond.gif[/img] Pot is 1600 and this is PLO8.

Everyone at the table is 5k-6k deep and the BB is 400.

What's the play/line?
