The Ultimate Free Throw situation

[fiasco]

A3 is fouled during an attempt for goal. The ball is mistakenly placed by your partner at the disposal of A1 at the free throw line. A1 shoots and misses.

Players and officials forget there should be two shots, and A2 rebounds the miss and makes a basket. After the ball goes in the basket but before it is at B’s disposal, the score table sounds the horn and tells the officials that A1 was entitled to another basket. They have awarded two points to team A. During this, you also realize that A3, not A1 is entitled to the free throw, and it is determined after discussing with your partner that A1 was deliberately deceptive in taking the free throw.
