Two on one within 3m
While the ball is in play, two teammates and one opponent all within 3m of it makes a 2-on-1.
It is only a violation if all three are actually involved in active play. Simply being within 3m is not yet a violation. The referee judges that.
Involvement is not only touching the ball. Blocking an opponent’s path counts, and so does gaining an advantage from a ball that rebounds off a post or off an opponent.
Not a 2-on-1 if one of the two teammates is the goalkeeper inside their own goal area.
Touching the goal area line at all counts as being inside it — lines belong to the area they bound. Fully outside, the exemption is gone.
Not a 2-on-1 if there is no opponent within 3m of the ball at all.
This app also excludes a goalkeeper who has gone fully over the goal line behind the goal — that part is the app’s own, not in the Laws.
The goalkeeper being exempt does not make the whole team exempt.
Leave the goalkeeper out, and if two teammates and one opponent are still involved within 3m of the ball, that is a 2-on-1 in its own right.
Driving off the court to avoid a 2-on-1 is allowed, as long as it is for the natural flow of play.
The player must not re-enter until that phase of play has ended, and must come back near where they left. It must not be dangerous, and it must not become a habit.
Otherwise it is unsporting behaviour and a caution.
When it is a violation, the opponents get an indirect free kick at that spot.
