Preflop he was playing 100% of hands as a call over 6 hands.

River I generally just find a fold here a lot, given the line, but I really have been running into a lot of recreational players donking these rivers larger with the straight, and making this weird donk with some weaker holdings like busted spades, 76, QJ, random KT, QT. etc. It may be variance and that is going to bias me to just wanting to call, I mean if he is really calling preflop so often he is going to have a ton of 8x in this line, and we don't beat any two pair nor do we beat KJ, or AJ that will show up here some some frequency as well.

What kinda of hand can we hero call the river with? Should we call two pair plus? I'm always awwed on the river when they show me their 96o lol. ideas are appreciated.
