It's a joke, she's never going to call with AJ. Given the preflop and postflop action, and the fact that she sounds pretty tight (folding a monster overpair to habitual bluffer Laak, in what smells like a bluff from here), gigabet probably put her on exactly AA-JJ and was trying to push her off. He probably ran some NASA simulation in his head and determined that the odds of her having KK were low enough that it was a +eV play.

Still, with all due deference, seems a little hard to defend that final river push, and I don't notice a lot of people here trying. Seems like *maybe* one of those caught-up-in-the-moment and/or getting *too far* off your normal game trying to capitalize on a perceived weakness in an opponent - situations that happens to even the great ones.
