Pool play, seeding and the bracket that follows

Almost every weekend event runs the same two-stage shape, and the join between the stages is where it gets interesting.

A weekend event has to produce a winner from a large field in about forty-eight hours, using a fixed number of courts. Almost every organiser solves that with the same two-stage structure: a round-robin group stage, then a single-elimination bracket seeded from the group results.

The group stage divides the field into pools, usually of three or four teams, with every team playing every other team in its pool. Pools of four are tidier, because each team plays three games and the arithmetic of the standings is straightforward. Pools of three are common when the field size does not divide neatly, and they are less satisfactory: two games is a very small sample on which to seed anything, and a single poor quarter can decide a team's whole weekend.

Seeding out of pool play is where the format does its real work, and where the tie-break order matters more than anything else in the rulebook. Head-to-head result is the usual first tie-break, which works cleanly for two teams and fails immediately for three teams in a cycle. The second tie-break is normally point differential, often capped so that a heavy win counts no more than a moderate one. The cap exists to remove the incentive to run up a score against a weak opponent, and an event that does not cap differential has effectively written that incentive into its rules.

Where differential is also level, organisers fall back on points allowed, then on a draw. It is worth reading the tie-break order before the first game rather than after the third, because it determines what a team should be trying to do in the closing minutes of a game that is already decided.

The bracket stage is single elimination, which is brutally efficient and tells you rather less than people assume. A single-elimination bracket answers the question of who won this weekend; it does not answer the question of which team is better, because one bad shooting half removes a team permanently. Formats that add a consolation bracket for eliminated teams are doing something genuinely useful, since they convert a lost weekend into more games played.

Bracket construction has its own conventions. A standard bracket places the top seed opposite the bottom seed and separates the top seeds into different halves, so that the two strongest teams can only meet in the final. Where pool winners advance, organisers usually reseed across pools rather than fixing brackets in advance, which is fairer but requires the whole field to finish its group stage before the bracket can be published.

Two practical features shape everything. The first is court supply: the number of courts fixes the number of games per hour, which fixes how many teams the field can hold. The second is the running clock. Many events run a clock that stops only in the final minutes and only for specific situations, in order to hold games to a predictable block. That single rule changes late-game strategy completely, because the standard practice of stopping the clock to extend a game does not work when the clock does not stop.

Read a schedule, then, from the back: find the tie-break order, find the clock rule, find whether there is a consolation bracket. Those three things determine what the weekend will actually feel like far more than the identity of the opponents.
