Hand 1: I bet and fold to ANY raise, even a minraise, then prolly c/f then river

Hand 2: I'd like to know his 3bet stats and if he's done this before, how many hands have you played with him btw? If he's played more than 50 hands I'd be inclined to call whilst if he's played less than 50 hands I'd be inclined to fold (only because before 50 hands are played anybody's stats can be skewed in either direction)

Hand 3: Pretty easy fold imo on the river
