with one partner throughout an entire event. Each pair will play many other pairs throughout the course of a session. Almost all Pairs games are scored by matchpoints, though a few are scored using IMPs.
Most pairs games use one of two types of movements. For larger games, per haps 8 or more tables, a "Mitchell" movement is used. North-South pairs re main stationary throughout; East-West pairs move to the next higher num- bered table after each round is completed, while the boards move to the next lower-numbered table. In games where a Mitchell movement is used, East-West pairs will remain East-West, and play most or all of the North-South pairs; North-South pairs will remain North-South and play most or all of the East- West pairs.
In case of an even number of tables, there may be a "skip" (East-West pairs will skip one table) near the middle of the game. Or there may be a "relay and bye- stand" (two tables share a set of boards while another set of boards is out of play). In the case on a half-table, there may be a "phantom pair" (the pair scheduled to play the non-existent pair will sit out for one round), or a "bump" (a roving pair will replace a different North-South or East-West pair each round).
Smaller games will usually use a "Howell" movement. There will be a small number of pairs who remain stationary (frequently only one). Other pairs will move around throughout the session, switching back and forth between North- South and East-West. Table cards indicating how each pair is to move are usu- ally provided. Each pair will play most or all of the other pairs in the game.
SWISS TEAMS: Swiss Teams is an event in which a team (of four, five or six players - with only four playing at a time) plays other teams short matches - usually somewhere between 5 and 9 boards. Each team sits North-South at one table, and East- West at a corresponding table, while a second team, its opponents for that match, sits East-West at the first and North-South at the second. (With an odd number of teams, a "three-way match", lasting for two rounds, may be re quired.) The results are almost always compared and scored by International Match Points (IMPs).
Pairings for the first round are random. Pairings for succeeding rounds are de- termined by a team's win-loss record or Victory Point total.
In events where the number of teams is small, each team may play every other team once. This is a "Round Robin" Team event. The scoring is the same as for Swiss Teams, but the pairings are usually predetermined.
KNOCKOUT TEAMS: Knockout Teams is an event in which a team (of four, five or six players - again only four playing at a time) plays another team in a long match - each match usually lasts an entire session (about 24 boards). The losing team is eliminated or "knocked out" while the winning team advances to the next round. Play con- tinues until only one team remains.
Unless the number of teams is an exact power of 2 (8,16,etc.), some three-way matches are required in the earlier rounds. In this case usually the top 2 teams in each group of 3 will advance, while one team is eliminated.
A "Compact Knockout" is a shorter version of Bracketed KO teams. Matches usually last 1/2 session (about 12 boards), and only 4 players are permitted on a team.
BOARD-a-MATCH TEAMS Board-a-Match Teams is an event where players enter as a team, but the scor- ing is similar to Matchpoints. Each team plays a small number of boards against (Continued on page 210)
