Could he be tilted enough to have AT in his 4 bet calling range? Smells like a combination of jts,qjs,kjs?? and AA. Problem is that if you bet he fold everything you beat. I can't think of anything he calls with except two overs cause he is so tiled. But if he is that tilted he can really have such a huge range that you might as well bet.

P.S. I thought you weren't going to be in Amsterdam, cause you seem to be playing !luck poker here, which is teribad...
