Hand 1. No. You beat a bluff and JJ, pitch it to his minraise.

Hand 2. Pot the turn! fold the river.

Hand 3. You're c-betting to fold AK-AQ, and I'm not completely sure they fold with a gutter and 2 overs at 10nl. As played call the turn.

Hand 4. I'm stacking off if only for the reason he min-raised preflop and his range includes any A or a FD.
