Final answer:
In basketball, a 2-1 fast break requires the player with the ball to draw the defender and either take a shot or pass to their teammate depending on the defender's actions.
Step-by-step explanation:
In a 2-1 fast-break scenario in basketball, the best procedure is to approach the situation with coordination between the two offensive players. The player with the ball should dribble towards the basket at a controlled pace, aiming to draw the single defender towards them. The non-dribbling player should run parallel and be ready to receive a pass. The player with the ball must make a timely decision, either by taking a shot if the defender commits to them or by passing to their teammate if the defender moves to cover the pass. This requires effective communication and observation of the defender's position to execute a successful play.
