Villain is playing 44/22 with a 20% AF on the river
In my experience, massive river over-shoves are common place at 10NL and very rarely bluffs; usually just fish trying to maximize value when they hit a monster.
Yeah agreed, I did fold it in the end and 99% sure he had the flush or better. The way I saw it if he keeps making donk moves like that I stack him soon enough.
