Preemptive War on Maniacs

Maniacs like to be the person who drives the action in a hand. This gives them a feeling of control, lets them believe that they are the bully at the table. They rarely know what to do when somebody stands up and punches them in the nose. Now, we don't mean you should physically assault your particular maniac, but take control of the hand before the flop. If the maniac raises, re-raise. This will confuse them because they rarely have to react to somebody else's overt aggression at the table.
