Villain has already donated some money to me...

[Kimo White Devil]

based on your read and his rvier aggression and you having position, If he ahs the case 8 or hits anything on the river, let him put the money in. i check turn/ and RAI on river. You have more history on him than us but if youre sure he bets rivers like a mofo go aheadand make him play his hand badly, dont let him make a good turn fold.
