Rob,

I think your AT fold is really bad. Obviously his most likely hand is a flush and a hand like 65s or T6s could also be betting. But there is too good of a chance he has a hand like T8/T9/JT/QT/KT that waited to see if overcards came and then decided to bet this "safe" river hoping to get a call from a worse pair or A high. Or that he has a ridiculous hand like A6, or he's making a ridiculous bluff with QJ.

I think this is an example of where you overvalued your read. Your read is good in that it tells you that you are beat a lot, more than one would expect without a read. But it's pretty much irrelevant, because the pot is laying you a good enough price (7 to 1) to call.
