Looking back I feel like it is a pretty clear call and don't think I was ever close to folding in-game either although I can admit I didn't snap the river shove.
At this level villain probably ships AA for value which means we are always calling especially with a sample size of 73
hands. Not much post flop info with only 73 hands and narrowing his range to nuts/2nd nuts for shoving that river based on his nitty preflop stats would be silly although I doubt it goes any further then AA which is all we need.
Also I can't really explain river sizing maybe I went to pot and misclick added another BB lol
I just recently started re-reading some stuff and one of the sections I just read was how stats even after ~500 hands(And more/less etc...) can be misleading although I'm sure that doesn't mean much in this spot.
