Don't be results oriented (that's why you're not supposed to post the results of the hand, or at least white them out).

Could you have asked for a better flop? You want K high to put all his chips in (which K6 did w/ out the boat and almost any Kx beats him). 10% of the time they're gonna catch their higher boat, hence "shit happens".

Also, I would not say you got beat by a better hand. Why is he playing K4 from EP? He almost succeeded in giving his chips away.
