Duel opportunity in a rectangle

A field is marked out with cones. A cone gate is built on both sides of the field. 8 field players position themselves according to the graphic on the edge of the field. The red players have a ball. To mark the approach line, a cone is placed on the side lines.

The red player A1 sprints to the starting line, ticks off and runs free. At this moment, player A2 plays the ball into his path. At the same moment, the blue defensive player B1 starts to attack A1. The offensive player tries to turn towards the cone goal of the blue team and to score a goal. If B1 comes into possession of the ball, he may score on the opposite goal. If the ball goes out or the duel lasts longer than 30 seconds, it is over and the next two players start. After 3 minutes the groups change positions and thus the right to attack also changes. If player A1 does not want to attack anymore, it is possible to play the ball into his cone goal to swap with one of his teammates. That would mean, for example, that A2 attacks B1. After 30 seconds the pair of players is automatically changed. Both teams count their goals. A goal only counts if the ball goes flat and without touching the cone. Alternative: - B passes the ball to A, it moves towards B at speed. - After the player has opened, the pass player may attack and a 2 against 1 is created. - After the player has opened, the pass player and a second defensive player may join in and a 2 against 2 is created.
