Hand 1: OOP, well defined hand. Make it something silly like $2 if you must raise here pre-flop. On the flop I would just keep betting into him. I think your turn line is a terrific way to stack off against better hands.

Hand 2: If you think his flop bet is legit, dump this on the flop. If he's weak maybe take a shot at him. You're looking at some nasty reverse implied odds here. Stronger players stack you here.
