hand 1, raise turn.
as played, easy overcall on river.

hand 2, let it go on flop. u bet once hoping to pick it up... u get raised, game over. unless the guy is a maniac, just let it go.

What he said.

On hand 1, I think donk-bets used to be called "weak-leads" by some. From many players they indicate a mid pair, or perhaps a mid-pair + draw combo, or even just a new draw. I really think you need to punish these donkbets. Both villains would probably be playing top pair more aggressively than this, so I think you even have a value bet on many river cards.

Hand 2, he has to be a known/maniac bluffer to make this call down. The only thing he can be representing is an ace, theres not much you can do.
