Folding AKo UI on River in Massive Pot (Party 10/20)

[yellowjack]

UTG is 33/10/1.5 after 75 hands
BB is 22/17/2.7 after 500 hands

Both BB and I are running good, up 25 BBs.

Party 10/20
UTG opens, I 3-bet from CO with AKo, BB caps. All call.

Flop is T55 - bet, call, I call.
Turn T - bet, call (all-in at this point), I call. I intend to fold the river unless I hit, as BB is TAG and has AA-QQ, AK-AQ always, and I assume will not bet AK and AQ on the river UI.
River 2 - bet, I fold.

Thoughts?

good

however, I'd say that he's less likely to have aq, and that he's more likely to continue to bet ui on the river, and that you're calling to grab half of an empty side a lot of the time.
