1: 3-bet preflop. postflop is fine. you have a gutterball on the turn. you have a solid top pair and backdoors on the flop and a maniac capper. no fold.

2: preflop is good, but i think you forgot that equity decreases when you miss on the turn. the flop is the easiest check raise in the history of flopped flush draws. the turn given the flop play is not a raise.

3: uh, limp preflop. i would call the flop and see what happens on the turn. no reason investing this much on the flop on this board.
