Fold KK on the flop?, 2/5 dollar NL

[SuperJez]

You have some good insight there both of you, much appreciated. I figured him for either a set or 78s. I could not see J9 either and cant see him being loose enough to play A9. 109 and JJ or QQ did run through my head, although if you think like that AA was also a possibility. I decided against going through with my hand (like you say if i call and a blank comes I have to go through with my kings. I figured he would have probably led the flop with JJ or QQ or check/called so I folded......

Thanks for the replies guys.
