Would you of felt better if he just beat you by hitting the flush. It's omaha, people chase, then once he hit K on turn, he's not gonna fold, he had 11 outs going into river. You screenshot doesn't show bet on turn but post flop bet was on .30?? so you wouldn't fold with a flush draw there either. I'm not an omaha expert lilg, but your starting hand doesn't look like a powerhouse either. I hate low sets in omaha, i seem to always lose a lot with that.
