First hand doesn't make too much sense, think about what you're trying to represent that you would check behind on the flop.
This is a very good point. A lot of players assume you have what you represent on the flop - in this case not a king. Athough at this level you might be called by QQ anyway. I've been trying to work out why some of my plo bluffs have been called and it is almost always because of some prior action that makes the holding I represent less likely.
