I dont know....based on what you've said about your table image and his solid play I could see him calling with KQ preflop. He may think you are loose and can pick you off down the line. I believe you made a mistake by just checking on the turn. His call on the flop didnt reveal much and you still do not have a real good idea where you are, and if you dont reraise you are denying yourself information. If you bet the turn and he raises you know where you are. If he folds, you've won a good pot. If he calls, you bet again on the river. I doubt he is holding AK.
