I think I'm the only person on this site that ever considers folding to overbet river shoves at lower stakes.
Seriously, to everyone who's suggesting that a small boat is doing this is just outside their damn minds.
What types of hands at small stakes overbet shove the river?
Uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
