If you have opponents who are paying attention this is a good 2nd line (rather than bet out on the flop when you hit) as if this one gets to showdown they will be less likely to bet after your checks in the future and you can then get some free cards when you flopped nothing.

Default against most opponents should be betting out though as an EP PFR checking a King high flop looks mighty suspicious to me. I am likely to check behind unless the King helped me too.
