1. Stats on BB are crucial. Against some opps. I'm folding to the pre-flop minraise. No matter what, I'm checking behind the turn. Most 50NL opponents aren't re-raising pre-flop with AQ or A9, which are about all you beat that call your flop bet.

2. Re-raise to $6 pre-flop, otherwise fine.

3. Re-raise pre-flop. Played well post-flop, imo.

4. Raise to $5 on the flop, otherwise fine.
