i'm not sure but i think the general idea behind checking with outs is when your out of position. seems like you let this one go a little early, there are a lot of draws out there that you don't want to give a free card to. i think you should have bet the turn, and tried to get to a free showdown. i'd probably fold to a check/raise. i think to check/raise a preflop raiser on a board with an ace, they'd have to have your kings beat pretty badly.
