my mistake for not realizing u were in position.
if its the case hes never putting more money in unless youre beat, probably you should just call here then fold the turn, and raise here everytime you have a bluff. i think u might be playing a bit too nitty if u cant get any action from a weaker hand in this spot, i mean, if the guy isnt even calling a raise w/ KJ this is about the most profitable spot you can find to bluff raise.
