Establish the format before the match
The 2026 FIP rules list a ten-point super tie-break as an alternative to the final set when the match reaches one set each. They also list a seven-point match tie-break alternative. The words “match tie-break” alone therefore do not tell everyone the point target.
Ask the organiser, or agree the format before a friendly match. If you are playing a full third set, reaching one set each does not automatically replace it with a ten-point decider. In competition, use the event's published format.
There is a concrete UK example in the LTA's 2026 referee and organiser guide: its FAST4 instructions specify a ten-point match tie-break at one set all, with two clear points required at 9–9. That is a documented competition format, not a claim that every UK match follows it.
