A special game played when a set reaches 6-6, where the first player to reach 7 points with a two-point lead wins the tiebreak and the set. Points are counted 1, 2, 3... instead of 15, 30, 40. Service alternates every two points after the first. Tiebreaks are some of the most intense passages of play in tennis. Every point matters and the pressure is relentless.
"Six-all, first set. We're going to a tiebreak. He's 3-1 up with a mini-break."
