All in.. This is a VERY riskey play, but my logic behind it is that if he is trying to push ace king, ace queen, ace jack.. you want to push him to a decision for all his chips. make him take a gamble, because he is also probable thinking even with ace king, I don't want to gamble. Most likly you will pick up the pot, you will have an advantage to ANY hand other then AA or KK. all in
