When someone min raises my Kings here and people start calling and building up a biggish multi way pot I'm making it 4 or 5 to go.

This will hopefully isolate the shortie so you can just push any flop if he calls. If the big stack calls you will be looking at a big pot where you can put some serious bets in.

As played raise the flop. Especially with the flush draw there.

He is probably donkish enough to call as he caught a piece so you were doomed in the hand, but you would feel better about yourself as you mucked!
