Took a shocking river beat the other day with my AA.

I’m holding AA raised the pot pre-flop to 20 dollars, get 2 callers.
Flop 8A8, nut FH so I bet 10 dollars to get callers, one folds.
Turn K, both of us check.
River 8.

I Bet 40 dollars he goes allin 130 dollars.
Have to call…
And he’s holding k8.

Disgusting
