Two Point Advantage

In tennis you always have to win by 2 points. So if the score is 40-40 and you win the next point, you haven’t won the game yet. Instead you have “advantage” (AD – 40). If you win the next point again, then you have won your game. That’s why some games seem to go on forever. Until one player achieves a two-point advantage, the game will go on and potentially go on forever. But, that’s also what makes tennis so exciting. Once you have won six games, you’ve won a set. But, wait, you are far from finished!
