Uber aggressive player/ what to do?

[AKQJ10]

Well, you certainly should be calling his all-ins with better than aces or kings, because he's plainly not waiting for jacks or better to push. From the description, it sounds like he has a pushing range at least down to about maybe 55 or A8. You don't want to widen your calling that range so much -- you definitely want to have a better hand, on average, than he figures to have. So maybe call his pushes with 99, AJ, or better. (WARNING: That's his pushes. In general AJ and 99 are awful hands against a big raise in NLHE.)

In general you want to trap him into playing over-aggressively when you have a big hand. Small pairs are good for this when they flop sets.
