A Forced Error in tennis happens when a player makes a mistake because of their opponent's good shot.
The opponent's shot is so difficult to return that it causes an error. Forced errors are different from unforced errors, which happen without pressure.
Top players like Rafael Nadal and Novak Djokovic are skilled at creating forced errors. They use powerful shots, tricky spins, or clever placement to make their opponents miss.
Forced errors are partly subjective and can be hard to judge sometimes.
