i dont know why you posted hand 1 other than to show that villain is capable of bluffing, but he played his hand fine. his river bet is fairly standard since you could just have Jx or something.

in hand 2 i think you definitely have to call a checkraise. he could easily have hit 2 pair and figures its probably good. 9:1 i think its a call. folding this hand on the river also seems really weak against a guy who is capable of abusing weakness.
