Hand 1:

Villain is 35/7. This should be a fold preflop, I think I was concentrating on another table and just clicked the button to complete without thinking about it. I should have raised flop and turn here right?

Hand 2:
Same villain as hand 1. We are both deep so I am playing this for set value. Given the weak bets relative to pot size, should I be raising it up here to try get a fold, folding, or trying to see a cheap showdown?

Hand 3:

Villain is 70/23
My reraise on the flop is very weak, this is deliberate as Im nervous of scaring the villain off, and am also trying to see if I can induce him to bet again.
