Look to attack the goal that is open. See if players can recognize where the pressue is. It should be easy to keep possession since the defense has so many goals to defend. Be patient in attack and don't take unnecessary risks. In defense, look to create opportunities to double team.
Variations Play with two balls to open game up.
Allow a goal if player dribbles in and out of square. Insist that passing goals require three players. Once a goal is scored, immediately attack going in the other direction. Only the attacking team can enter this area. This is a possession game that uses the keepers.
