I never do. If I have Kings there is probably only 1 person that called my preflop bet to begin with.

I will bet it 3-5 somewhere and see what they do. A lot of times you get called with lower pairs that will fold. The only thing I am usually worried about is AK because AA I usually would get a reraise with. Im not too worried about it though and will still bet it to see where they stand.

A lot of times they will fold right there. KQs is kind of hard telling since you arent even paired and would have to hit 2 running cards to help you significantly. That one depends a lot more on other circumstances I guess but KK is never an auto fold.
