Mitchell Movement, for the same number of tables. The shortfall from a Complete Howell Movement creates an equal number of quasi-stationary positions at "swivel tables" for the pairs with numbers greater than the number of rounds but less than the number of pairs. Each quasi-stationary pair remains at the same table throughout the session, but plays North–South in some rounds and East–West in other rounds, usually achieved by arrow switches at the respective tables rather than by having the quasi-stationary players physically change seats. All stationary and quasi-stationary pairs play against each of the moving pairs but not against each other, while the moving pairs don't play against an equal number of the other moving pairs. The following table shows the Partial Howell Movement for six tables playing eight rounds supplied by the ACBLscore® scoring program published by the American Contract Bridge League. Pair 12 is truly stationary, playing North-South at Table 1 throughout. The quasi-stationary pairs are Pair 11 at Table 2, Pair 10 at Table 3, and Pair 9 at Table 4. In this particular movement, three subsets of entrants do not play against the other members of their own subset. These subsets consist of the stationary and quasi-stationary pairs (Pair 9, Pair 10, Pair 11, and Pair 12), the odd moving pairs (Pair 1, Pair 3, Pair 5, and Pair 7), and the even moving pairs (Pair 2, Pair 4, Pair 6, and Pair 8).

boards in the board group that it receives, then passes those boards to the next lower table, which also plays them, while retaining but not playing the other half of the boards in the board group that it received initially. At the end of the first scissors round, the boards played twice get passed again and join the boards not played in the previous round at that table to form a new board group. The new board group remains intact until the second scissors round, which is half of the total number of rounds after the first. In the second scissors round, the boards played twice in the first scissors round are set aside and the boards not played in the second scissors round are played twice in the same manner. After the second scissors round, the boards played twice are passed again to reconstitute the original board group. The following table shows a Scissors Mitchell Movement of six tables playing six full rounds, with the halves of the initial board groups designated numerically (that is, the initial board group A consists of halves A1 and A2).
5306:, has most pairs progress from table to table in a cycle that causes each pair to play against most or all of the other pairs for one round and each pair to play all of the boards (deals) in play during the session. All moving pairs follow the same progression, so each pair goes to the position occupied by the pair with the next lower number in the preceding round with Pair #1 going to the place occupied by the pair with the number equal to the number of rounds. The pair with the highest number sits North–South (at Table 1 in most, but not all, Howell movements) and does not move from that position, and the number of each moving pair is the round in which it sits East–West at that table. If the number of rounds is less than the number of pairs by more than one, the additional pairs are quasi-stationary—they remain at one table for the entire session, but play some rounds in each direction. The director may place a card at each table or issue a slip of paper called a guide card to each pair with the instructions for the movement. 6303:
quasi-stationary pairs so the stationary and quasi-stationary pairs would have direct comparisons on about half of the boards—which the mathematical analysis has subsequently proven to be wrong. The result is a hideous imbalance in the fairness of the movement. This issue does not affect published Complete Howell Movements described, but only because all pairs of entrants play against each other in a Complete Howell Movement so the correction affects the weight of opposition of all pairs of entrants in the same way. The next table shows the frequencies of number of comparisons reported by the ACBLscore® scoring program for this movement and the subsequent table shows the pairs that represent the most extreme outliers as reported by the ACBLscore® scoring program, with asterisks (*) indicating pairs that do not play in direct opposition at the same table. The pairings with asterisks in the first three rows and the pairings without asterisks in the last two rows are the most egregiously imbalanced in this movement.

up more points for failing to make any contract. These higher scores for the same Bridge result also translate to more IMPs for the same pair of different Bridge results in IMP scoring. When scoring by either of these methods, all pairs should be vulnerable on an equal number of deals—a condition most easily met by playing four boards per round since all regular groups of four boards (1–4, 5–8, etc.) have one board with each combination of vulnerability (none, North–South only, East–West only, and both), ensuring that each partnership is vulnerable on two deals and not vulnerable on the other two deals. Some movements that do not meet this criterion have very bad imbalances of vulnerability. This issue does not apply to standard Matchpoint scoring because all boards award an equal number of matchpoints in each direction regardless of vulnerability.

RealBridge. This in fact greatly simplifies bridge movements. In traditional movements such as the Mitchell and Howell movements, both players and boards circulate continuously in different ways, and considerable ingenuity is needed to avoid conflicts and ensure that a pair does not play the same boards twice. In a barometer movement all players play the same boards simultaneously, and all that is required is to rotate the players. In pairs games, either two-winner movements or one-winner movements with arrow switching are easily performed. Head-to-head teams matches and multiple teams events with an even number of teams are also straightforward. Multiple teams events with odd numbers of teams are trickier; either one team has to sit out each round, or some boards have to be played at different times to give the effect of a "long triple".

beginning with the last board group. It is theoretically possible to run this movement with only one set of boards as described in the linked article, but players will not like it, especially if there is no sit-out, because the last table shares boards with a different table in each round, creating complicated intra-round board exchanges, and there is a three-way share between Table 1 and the last two tables in the middle round if the number of rounds is odd. It would be considerably less intolerable to run this movement with just one set of boards if there is a phantom pair seated North-South at the last table, leaving the share between Table 1 and the penultimate table as the only active share. Still, it is better to use two copies of the boards so that the only active share is between the last two tables in the middle round.

with similar records to oppose each other in the next round, subject to the constraint that no team can play against another team in more than one round. The "Swiss" terminology originated from its use in multi-round chess tournaments. This causes stronger teams to come into competition with other stronger teams that are doing well in the fight for the top, weaker teams to come into competition with other weaker teams in the fight to the bottom, and average teams to gravitate toward the middle of the standing (because an average team that beats a weaker team by a significant margin then must play against a stronger team and vice versa). Most computer scoring programs now generate subsequent matches automatically, with algorithms that are sophisticated enough to ensure that undesirable assignments won't arise in the later rounds.
6770:
three of the four tables. In the last three rounds, the pairs that started North–South play a Complete Howell Movement at Table 1 and Table 2 while the pairs that started East–West play another Complete Howell Movement at Table 3 and Table 4. The configuration of the arrow switches in the first four rounds and the positioning of pairs in the last three rounds conspire to balance the movement perfectly—each pair of entrants plays one group of boards against each other at the same table, three groups of boards in the same direction at different tables, and three groups of boards in opposite directions at different tables. This particular movement works best with two copies of the boards, but it can run with Table 1 sharing boards with Table 2 and Table 3 sharing boards with Table 4 throughout if necessary.
7063:
Pair 1 is fully stationary, Pair 2 changes tables only once, and Pair 6 changes tables only twice—generally acceptable, or at least tolerable, accommodations for players who have some degree of mobility impairment—whereas the Complete Howell Movement requires five of the six pairs to change tables after every round. The balance of comparisons and the existence of a "free for all round" are the same as in any Complete Howell Movement for three tables, so there is no "down side" whatsoever to using this movement instead of the Complete Howell movement. The previous discussion pertaining to the "free for all round" in a Complete Howell Movement for three tables is also applicable here—it is best to provide three copies of the boards in Board Group E so each table can have its own copy.

different tables, thus generating direct comparisons), teaming (in opposing directions at different tables), and, in individual movements, partnership (opposite seats at the same table). Mathematical analysis of standard matchpoint scoring has derived the weight of opposition in the following table based upon the impact of a hypothetical entrant getting either extreme (clear top or clear bottom) scores on all deals compared to a hypothetical entrant getting average scores on all deals. Positive weights means that the entrants are adversaries (an abnormally good result by either hurts the other) and negative weights mean that the entrants are effectively teammates -- that is, an abnormally good result by either helps the other. The term "scoring unit" is that of Law 78A of the

boards each when all other competitors are playing 8 board matches); this is sometimes known as a "short triple". In the second case, each set of interleaved matches requires two rounds of play, known as a "long triple". This means that the number of rounds must be even. Also, because the teams involved will not have results to compare for future pairings for two rounds, in the later rounds it is desirable to avoid assigning the leading teams to a "long triple". In both cases, each team's North–South pair plays one side of one match while its East–West pair plays one side of another match in the first half of the interleaved matches. In the second half, each pair play the other side of the match that the other pair played in the first half. The team then scores both matches.

the session. In this situation, it is best to have all entrants play approximately the first half of the deals before the break, constituting the first stanza, and the remaining deals after the break, constituting the second stanza, so that there is no potential for discussion of deals during the break to compromise the play of any deals in the remaining rounds. The following table shows a Two Stanza Mitchell Movement for six tables with a break after the third round. The players and boards move in the normal manner for a Mitchell movement, except that all boards played in the first stanza go out of play and new boards come into play at the break. Note that this movement works best with enough copies of the boards so to eliminate physical sharing.
4222:
of a session. The use of a movement consisting of two stanzas, each of which is the basic Web Movement described above, ensures that any discussion of deals that might occur during the break will not compromise the play of those deals after the break. The following table shows a Double Web Movement for eight tables in which the first five rounds are the first Web Movement and the last three rounds are the second Web Movement. This particular movement will run smoothly with two copies of the boards in Board Groups A–E and three copies of the boards in Board Groups F-H, with Table 7 and Table 8 sharing one copy of Board Group G in Round 7, but it is best to duplicate four copies of the boards in advance if one intends to run a Double Web Movement.
4710:/8, which means that arrow switches on one-eighth (1/8) of the rounds provides the best achievable balance. Thus, the English Bridge Union (EBU) formally recommends this practice. This roughly translates into arrow switches at all tables of the last round when playing six to nine rounds and in the last two rounds when playing twelve or thirteen rounds, provided that two tables are not playing the same group of boards -- the arrow switches should occur on a different group of boards, or a different pair of groups of boards, at each table, in any case. Of course, the balance is not perfect —- entrants who have arrow switches on the same group(s) of boards, including those in direct opposition on the affected rounds, will be outliers. 7835:
will be small. When this is not desirable, some other form of arranging competitors to play must be used. The most common are Knockouts and Swiss. In both of these, teams play head-to-head matches of a convenient number of boards in each round. In Knockouts, match winners advance to the next round; the losers are eliminated from the event. In a "Swiss Teams" competition, the first match may be assigned randomly and subsequent matches assigned dynamically based upon the outcome of the previous matches across the entire field. Another possibility is to divide the entrants into brackets based on ability or ranking, and they play the other entrants in their own bracket in a "Round Robin" format.
6766:
session. Thus, an event with sixteen pairs would play a Relay and Bye Stand Mitchell Movement (eight rounds) in the first session followed by separate Complete Howell Movements (seven rounds) for each of the original fields in the second session, so that each entrant would play against each of the other entrants in one session or the other. A Hybrid Movement takes the same approach to form two stanzas within a single session. A complete Hybrid Movement is functionally equivalent to a Complete Howell Movement, but it has several pairs that don't change tables after every round—thus providing better accommodation for players with disabilities and mobility impairments.
379:
boards (deals) move down one table, with boards leaving the first table going to the last table. The first group of boards normally starts at Table #1, the second group at Table #2, etc., so the North–South pairs play consecutive groups of boards in ascending order and consecutive East–West pairs in descending order while the East–West players play alternate groups of boards and consecutive North-South pairs, both in ascending order, as the movement progresses. The table below shows the East–West pair (EW) and the board group (BG) at each table in a Basic Mitchell Movement for five tables with five rounds of play.
675:
boards that they played in the first round at the midpoint of a complete movement, requiring a variant of the movement. The most common variants for an even number of tables, both discussed below, are the Skip Mitchell Movement, used when the number of tables does not allow a complete movement, and the Relay and Bye Stand Mitchell Movement, also called the Relay and Share Mitchell Movement in the United Kingdom, for a complete movement. However, this restriction does not apply to the "Barometer" form of the movement in which all tables play the same deals in each round, as illustrated in the following table.
4639:" so the stationary pairs do not physically change seats, to diminish this disparity. The pairs that start North–South remain at the same table for the entire session and the pairs who start East–West continue to move after each round, even when they play in the opposite direction. With the introduction of arrow switches, the movement becomes a Scrambled Mitchell Movement. More specifically, one can prepend the word "Scrambled" to that of the specific Mitchell Movement that gets scrambled (for example, a "Scrambled Relay and Bye Stand Mitchell Movement" or a "Scrambled Crisscross Mitchell Movement"). 337:
Movements have separate fields of North-South pairs and East-West pairs, so they have usually have separate rankings and winners in each direction, whereas One Winner Movements typically have some pairs play in some rounds in each direction, requiring all pairs to score in a single field that produces just one winner—hence the name. One Winner are typically used for games with only a few tables because they permit play of more rounds than Normal Mitchell Movements, which limit the number of rounds to the number of tables. A Mitchell movement can be converted to a one-winner movement by arrow switching.
4722:
the other half of the boards in each round with the first bump occurring in the second half of the first round, thus cutting the duration of the sit-out in half. These movements, which require "One Winner" scoring because the roving pair has comparisons in both directions, are most commonly used for games with either thirteen or fifteen pairs, the respective underlying movements being the "one winner" variants of a Relay and Bye Stand Mitchell Movement for six full tables and a Straight Mitchell Movement for seven full tables. In this movement, the pairs that start East–West add the number of

another table, or in situations in which there is not space for another table. In its standard form, the roving pair displaces only North–South or East–West pairs and scores in the respective field. The roving pair usually sits out in the first round, and other pairs sit out in subsequent rounds when the roving pair displaces them. The following table illustrates an East–West Rover Mitchell Movement for five tables playing five rounds; the roving pair is East–West Pair 6. Note that East–West Pair 5 is not "bumped" and thus plays all of the boards in the session.
6038:
two-thirds of the boards on each table with instructions to pass the first board or two, as required, to the next lower table upon completion thereof) and most smoothly with three copies (so each table has its own). If there is only one copy of these boards, the director should manage the order of play at each table to ensure that each table completing a board moves on to the available board with the fewest completed plays. Otherwise, two tables inevitably end up needing the same board for their last play, forcing one table to wait while the other plays it.
3070:
capability is what allows use of a Web Movement to play an odd number of rounds when the number of tables is odd. The following table shows the Web movement for eleven tables playing five rounds, obtained by prepending one subsection of five tables to the web in the preceding example (now at tables 6–11). The groups of boards move normally between the prepended subsection(s) and the lower half of the web, with boards from Table 1 going to the bye stand at the highest table in the lower subsection of the actual web (Table 8 in this example).
2688:
pair in the first round and the boards that the roving pair is playing against the pair displaced by the roving pair in each subsequent round. The following table shows the Rover Mitchell Movement above with the addition of a party table (in this example, Table 6, with the added pair becoming North-South Pair 6). It is best to duplicate a separate set of boards for the "party table" because the "party table" plays the same deals as each of the other tables in one round, creating an awkward situation with actual sharing of boards.
239:
not play against a very strong competitor, thus gaining a significant advantage, while another entrant does not play against a very weak competitor, thus incurring a significant disadvantage. When a movement is several rounds short of complete, averaging tends to take over—each competitor misses both weaker and stronger opponents, diminishing the effect. It is possible to diminish this impact further by "seeding" the field—that is, by dispersing entrants with higher and lower rankings or ability uniformly throughout the field.

Mitchell movement as described below), but this may vary in other regions. Of course, a club may choose to play fewer deals in a session connected with a luncheon, party, or some other event or to ensure that an evening session ends at a reasonable hour for players who must go to work on the next day, and sessions on cruise ships also typically are shorter (about 18-20 deals). Sessions for less experienced players also typically consist of fewer deals and, conversely, sessions of some championship events may play more deals.
5110:
in a Mitchell movement, except they play a round in each direction at the hesitation table before continuing on to the next table. Thus, each moving pair plays the pair that precedes it and the pair that follows it the rotation in addition to playing against each of the stationary pairs. The boards move down, passing through a bye stand directly opposite the hesitation table. The following table shows a Hesitation Mitchell Movement for five tables with arrow switches on the last round except at the hesitation table.
5858:-1 of the other pairs. The consistency of this pattern clearly suggests a fundamental mathematical limitation, but the present author has not yet found mathematical proof thereof. However, this relationship strongly suggests that a pair that is an extreme outlier in terms of playing ability or ranking compared to the rest of the field—either particularly strong or particularly weak—should be seated in the position that has the perfectly balanced comparisons to avoid skewing the results of the rest of the field. 362:
players seated in the same direction do not play all of the same deals in many Mitchell Movements, and thus have different weight of opposition, (2) pairs who play in direct opposition typically play more or fewer of the same board groups, resulting in different weight of opposition, and (3) pairs seated in opposite directions that do not oppose each other constructively become teammates. The Web Movement and Double Web Movement, described below, eliminate the first two of these issues but amplify the third.
5862:
situation does not have enough degrees of freedom to do otherwise. The director normally will need to move the boards when running this movement, as most players don't know the non-standard movement of the boards. The Extended Hesitation Mitchell Movement, described below, is usually a better choice for games with three tables—it runs more smoothly because the boards move in a normal manner in the first four rounds and it offers better accommodation for players with disabilities or impaired mobility.
2088:
competitions, such as multiple teams events or "Board-a-Match" (BAM), as discussed below. Note that the numbers of the North–South pair (table) and the East–West pair playing each group of boards in Round 2 and Round 5 are reversed, and the same is true of the numbers of the North–South pair (table) and the East–West pair playing each group of boards in Round 3 and Round 4. In BAM competition, the North-South and East-West pairs with the same number are the two partnerships of the respective team.
869:
Mitchell Movement. However, the skip limits the number of rounds to one less than the number of tables so the movement cannot be complete. Thus, a Skip Mitchell is normally preferred only when the number of tables makes a complete movement impracticable. The following table shows a Skip Mitchell movement for ten tables playing nine rounds. Note that one more rotation would bring the East–West pairs back to their starting tables and to their opponents in the first round.
3380:
group of boards only in the middle round if the number of rounds is odd, as illustrated by the following table showing a web of ten tables playing five rounds (with asterisks indicating the shared group of boards in the middle round). The simplest board movement is that boards played at the highest table go to a bye stand at the next lower table and boards played at Table 1 going to the bye stand next to the highest table, as this movement remains constant throughout.
317:
sometimes upon completion of each board, with competitors moving up and down like a barometer. Although people sometimes say "Barometer Movement" in reference to any movement used in a barometer game, there really is no specific movement by that name. Rather, a barometer game can use any of the movements for individual or pair games described below, but with each table playing the groups of boards in order from first to last rather than as indicated in the tables.
4626:(North–South) pairs to retain their pair numbers while the moving (East-West) pairs add the number of tables to their starting table to get their pair number. Thus, in a "One Winner" Mitchell movement with seven tables, pairs 1–7, starting North-South at the respective tables, would be stationary and pairs 8–14, starting East–West at tables 1–7 respectively, would move. However, this movement is not ideal because the weight of opposition is far from balanced. 366:
East-West fields across all sections for scoring. The latter practice actually exacerbates the imbalance in weight of opposition of an incomplete movement because it amplifies the weight of direct opposition while rendering pairs playing in opposite directions of different fields as constructive teammates for the entire session. With each section having separate fields, the entrants in different sections have no weight of opposition on each others' results.
5830:-1 rounds in opposite directions at other tables with respect to each of the other pairs to achieve the proper balance of comparisons, and thus equal weight of opposition, for a fair movement. Complete Howell Movements that achieve this exist for reasonable even numbers of tables, but are not known to exist for any odd number of tables. When the number of tables is odd, the Complete Howell Movements that come closest to meeting this goal have one pair with 8299:
any two teams play the same boards in both directions. The most common team movement is the American Whist League (AWL) movement described above, with the first round removed (so a team's North-South pair does not play against its own East-West pair). However, the teams may shuffle and deal the boards that would be at their table in Round 1 of the AWL Movement, which are boards that they won't play, before moving for the first round of actual competition.
5106:
which the number of rounds is one greater than the number of tables—most commonly, five tables play six rounds, seven tables play eight rounds, or eleven tables play twelve rounds. It is also a specific Partial Howell Movement, but it is more readily described here because the numbering of pairs follows that of a "One Winner" Mitchell Movement rather than the normal convention of the Howell Movement described below.
1258:
permitting a complete movement with an even number of tables. To make this happen, two consecutive tables play the same group of boards in each round throughout the session while the opposite group of boards sits out of play on a table or stand between the tables directly opposite the tables that are playing the same deals—and it is here that regional differences in terminology may be a source of confusion.
8261:
combination thereof, each of which is one round in duration. A three-way match consists of three round-robin "half-matches" (so each side of a three-way match plays half the number of deals of a head-to-head match in the same round). The winner of each head-to-head match continues into the next round while the loser is eliminated. In a three-way match, two teams may continue with one team eliminated or

field score and place separately, so there is a winner in each field. Pairs are identified by the number of the table where they start and their direction of play (for example, Pair 3 North–South or Pair 5 East–West). The pairs seated North-South typically remain at the same table through every round of play, while groups of boards and East–West pairs go to different tables at the end of each round.
1614:
would use the other, with boards entering at Table 6 and exiting at Table 3. The remaining boards of each set usually are placed on stands next to the table where they will enter. During the round before the midpoint of the movement (Round 4 in the example), the director brings the boards that have exited on each side to the stand next to the table where they will reenter later in the session.
856:
missing actual pair. The pairs playing in the opposite direction "sit out" when scheduled to play the phantom pair, so they do not play the respective deals (boards). The Rover Mitchell Movement and Two-Way Rover Mitchell Movement, both described below, in which the odd pair displaces a different pair each round with the displaced pair sitting out, are alternative options in this situation.
25: 160:
practically means that the number of rounds must be at least 70% of the number of groups of boards in play. The American Contract Bridge League (ACBL) likewise requires at least 2 1/2 tables for a sanctioned standard pairs game, even though there is a valid movement for such a game, while permitting two tables to play an individual game with a "One Winner" Movement or a team matches.
6448:
Complete Howell Movement with an odd number of tables discussed above, amplified by the fact that each round plays 20% of the boards. The following table shows a Scissors Howell Movement for three tables in which the half board groups move in a complementary manner so that the imbalance of the upper half countering the imbalance of the lower half, creating a balanced movement.
4913:
already assigned. Note that each displaced pair should sit opposite its normal direction while playing at the "party table" to obtain a better balance of comparisons. Thus, both the pair that remains at the party table and the roving pair play half of the boards of each round in each direction. The following table shows the addition of a "party table" to the above movement.
2307:>> With twelve tables, all East–West pairs move normally (that is, up one table after each round) except after Round 3 and Round 9, when they move up four tables. For the East–West pairs, the tables skipped after Round 3 are the tables played in the last three rounds and the tables skipped after Round 9 are the tables played in the first three rounds. 358:(0) for every complete Mitchell Movement because the number of comparisons for each deal that they play in direct opposition is exactly equal to the number of rounds in which they play in opposite directions at different tables, and all pairs in the same field have the same weight of opposition because they play every deal in the same direction. 6939:
pair that it did not play in the first five rounds of the movement. The fifth round is really an extension of the Hesitation Mitchell Movement rather than the parallel Howell movements that normally form the second part of a hybrid movement; hence the difference in name. The following table shows this Extended Hesitation Mitchell Movement.
222:
there are several variations of these options—a separate comparison field for each direction within each flight, a single comparison field in each direction across multiple sections, a single comparison field across both directions within each section with section, or a single comparison field encompassing all entrants in the entire event.
7089:
alternatives are given by Partial Howell Movements, Hesitation Mitchell Movements (odd numbers of tables), and Double Hesitation Mitchell Movements (even numbers of tables). However, the director needs to consider circumstances such as the need for stationary places to accommodate players with disabilities in making the final selection.
2870:, with additional groups of boards on a bye stand next to the highest table of each subsection. The East-West pairs move normally (up one table each round except in the case of a skip) within or through the web. The Web Movement in which six tables play five rounds, shown in the following table, illustrates how this works. 6930:
second part of the movement, the stationary pairs play a Complete Howell Movement while the moving pairs play a Partial Howell Movement in which they "miss" the pairs that they played at the hesitation table. With three tables, this movement becomes the Extended Hesitation Mitchell Movement described below.
8298:
A Board-a-Match (BAM) event is a Swiss Team competition in which each board is deemed to be a separate match, with a winner and a loser. These events typically consist of each team playing a few boards against each of the other teams, using a movement similar to that for pair games but engineered so
8260:
In a knockout competition, the entrants are typically divided into brackets of nine to sixteen teams and assigned initial positions within each bracket by a random draw for starting positions on the bracket chart. Each round of matches may consist of either head-to-head or three-way matches, or some
8174:
A round robin for seven or nine teams could operate as three or four rings, respectively, of interleaved matches, but the more prevalent practice is for three teams to play interleaved matches and the remaining teams to play head-to-head matches in each pair of rounds. With nine teams, there is also
8040:
The format recommended by the American Contract Bridge League (ACBL) for five teams consists of two rings of interleaved matches shown in the following table, as this allows the players to score the first two matches after the second round. The last two rounds can use the same deals as the first two
8023:
The movement of the boards can present challenges to ensure that the two opposing pairs of the two teams in a match play the same boards even though they meet in different rounds. The straightforward American Whist movement requires an odd number of teams, so it only works if one pair of teams do not
7851:
The following table shows interleaved matches for three teams. The teams are designated by lower case letters in this table rather than numbers because their numbers don't necessarily match the numbers of the tables, but the movement really consists of the second and third rounds a Standard Mitchell
7244:
In a Swiss Pairs competition, a large number of entrants play individual head-to-head matches in each round, typically over 6, 7 or 8 boards, all using the same sets of boards. The matchpoint scores on each board are compared across the entire field, and the opposing pairs' total scores for the round
7075:
Complete Howell Movements ensure that each entrant plays against all of the other entrants, but the number of rounds and boards varies and may not be convenient. All pairs, except one, move after every round, which slows down the move especially if one table is slow, and there is only one stationary
6938:
In a game of just three tables, the Hesitation Mitchell Movement that would form the first part of a Hybrid Movement pits each pair against four of the other five pairs in the first four rounds. This reduces the second stage to one round in which each pair plays the fifth group of boards against the
6447:
The Scissors Howell Movement cuts each board group in half, with each half moving independently, in the same manner as the Scissors Mitchell Movement described above. This movement is most useful with three tables, where the boards can move in a manner that offsets the imbalance in comparisons for a
5543:
A Complete Howell Movement normally is practicable only for smaller games with a few tables, as the number of rounds becomes prohibitive for normal games with eight or more tables, but it is sometimes used in tournament situations. The following tables show the practicable Complete Howell Movements.
5325:
Howell movements also have a limited number of stationary or quasi-stationary positions to accommodate players who have difficulty moving due to physical disabilities and other mobility impairments. The number of such positions in any Howell movement is the difference between the number of pairs and

A Double Hesitation Mitchell Movement has two points where moving pairs play North–South, though not normally at directly rotating tables, so that the number of rounds is two more than the number of tables. Thus, six tables can play eight rounds of three boards rather than six rounds of four boards.
5109:
In the Hesitation Mitchell Movement, the pairs seated North–South at every table but one are stationary for the entire movement. The hesitation table, which is usually the table with the highest number, does not have a stationary pair. The moving pairs move up one table at the end of each round, as

is the specific case of the Web Movement described above in which the actual web consists of two tables and there is exactly one add-on block. In this movement, the next to last table plays the same group of boards as Table #1 in each round, and the last table plays the board groups in reverse order

The number of tables in a web can be twice the number of rounds, but it is better to reduce the web to zero tables with two prepended subsections since this arrangement allows all boards to move in the normal manner of a Standard Mitchell Movement. To illustrate this point, the following tables show
3379:
In the special case in which prepended subsections reduce the actual web to just two tables as in the following example of a web of seven tables playing five rounds, it is possible to use just one set of the boards for both sides of the web. In this situation, the two tables in the web play the same
3069:
One can prepend any number of additional subsections in which the number of tables is equal to the number of rounds onto any web, but each additional subsection requires an additional copy of the boards for the movement to run smoothly. Since the number of tables in the actual web must be even, this

One option is to use a separate set of boards on each side of the movement, as demarked by the relay and bye stand (or share and relay). In the example movement above, Tables 1, 2, 7, and 8 would use one set of boards, with boards entering at Table 2 and exiting at Table 7, and Tables 3, 4, 5, and 6

If a modern board duplicating machine is available, the director can duplicate an additional set of boards for one of the two tables that are playing the same deals. With two tables sharing boards in more than one section, the director can position the tables sharing boards in different locations in

The Skip Mitchell Movement provides a simple vehicle to accommodate players who arrive after a Standard Mitchell Movement or a Skip Mitchell Movement is set. The director need only place additional board groups on the additional tables and add or remove the skip, depending upon whether the number of

In a complete Mitchell Movement, the number of rounds is equal to both the number of tables and the number of groups of boards actually played during the session, so all of the pairs seated in each direction play one round against each of the pairs seated in the other direction and all pairs play all

A complete movement, in which each entrant plays against all of the other entrants or in which all entrants in each scoring field play against all of the same field of opponents, is inherently the fairest choice. The worst scenario is a movement that is one round short of complete: one entrant does

Some organizers may prefer to divide the tables of a session into flights for players of different ranking or experience levels with the flights playing in separate sections and scored separately. This choice typically requires a different movement for each section to accommodate differences in size
