Hmm. AA and KJ are the only hands I see conceivably betting then calling your river push that you beat. And JJ and KK beat you. So I guess it depends on your read of the player (i.e. how tight/aware he is). Since I think a solid player would fold AA on the river, then only 1 hand calls you and two hands beat you (maybe three if he raised with a low pocket pair and caught mid-set). So I'd just call - if a non A K or Q river came I would push his bet. But what do I know, I would have bet the turn!
