I agree with Beanfacekilla too. Weak suited kings aren't that great, even in multiway pots. We really have to smash the flop to continue, and we don't flop trips/two pairs/flushes enough. Flopping a lone pair of kings/even trip kings or two pair give us reverse implied
odds against better kings. And when we flop a flush draw, we may not reach showdown or see a cheap turn/river since people go crazy about "protecting" their hand in multiway pots.
I'd rather much limp behind here with any suited ace and decent suited connectors. We can draw to/flop the nuts and make much stronger
hands, which is important in multiway pots.
Even if you do profit limping K3s behind here, I imagine it wouldn't be much despite the terrible level of play at 1/2.
And like Bean said, I don't like shipping or calling flop either because we don't have any FE and also because most of the time our K/3 outs aren't clean.
