A few groundrules for the tournament:
* Format is single-elimination.
* Place and time to play a match is arranged between the 2 players.
* Try to play your match within one week when your opponent is ready;
  the Tournament Director reserves the right to default one or both players
  of a lagging match, without notice, so the tournament can progress.
* Each player brings a new can of balls and one can is used for the match;
  winner keeps unopened can and loser keeps the used can.
* Play 2 out of 3 sets.  If the set goes to 6-6, play a 12-point tie-breaker
  (first to win more than 6 points and lead by at least 2 points).
* Only 1 player (usually the winner) should report the result.
