I am with toss here that you need to fold this pre-flop unless you have noticed ALOT of cold calling. KQs isnt an ideal hand HU against an EP raiser (for domination reasons), you need to KNOW that you are going to get some more people in this hand to make coldcalling here profitable.

I much prefer raising the flop to just calling here. I think it makes the hand alot easier to play down the line not to mention you are ahead here a fair amount of the time. If he calls your raise then lines you up on the turn for the checkraise then its an easier fold.
