Donk of death the river?

[MitchL]

Definitely bet. Loose passives love to check the river with 2pair if any sort of scare card comes. There is no scarier card than the Ace in this spot. Your hand looks exactly like what it is. I think his range is probably weighted more heavily towards a set, but losing a river bet here would be very bad.

Edit to add-Actually Im not sure if his range is weighted more towards a set. Even a passive player should be raising any Q on the flop.
