If there's an odd number of players then make 1 player (preferably a midfielder) a neutral player who always belongs to the BB team.
The right of attack is taken over the 23 meter line by playing three times.
The right of attack is lost only when the other side has reached the right.
An interception does not change this.
3 cause penalty corner is a penalty ball (goal is to focus on effectiveness in the circle).
2 x 10 minutes with 5 minutes rest (match situation).
Each team can be given an assignment such as full press / half court / put pressure on certain player when he gets the ball to improve strategy and coaching among themselves.
Provide enough balls along the lines so that there can be a high ball tempo.
