I value bet that river against pretty much anyone.

There are only two cards that you're really worried about here. If he had one of them, you probably would have known on the turn. Some will slowplay it though, so the possibility he has trip aces is still there. However, he also knows that with paired aces on the board it's less likely you have one. So I'd say almost all players will call you on the river with QQ, just a jack, and worse. If you check to passive players here, they will usually take the free showdown here if they have a worse hand.
