2/4 AKo UTG: Bet this river with 2 pair?

[Beck]

Yes, the number of hands that he may call with that I actually beat is very limited.
If I bet out, I'll lose two BB when behind, and only rarely gain one when ahead. By checking I also allow him to make a bluff at the pot.

I think I bet the river here HU against a complete donk villain (at 2/4 level at least). People with the PT stats you gave at this level will often call through with pretty trashy hands and TP any kicker.

There will be times where you'll get raised behind and shown a rivered flush or a slowplayed set or straight, but value betting against loose donks is a must.
