74-416: The tournament is contested in a single block round-robin format with all teams facing each other once. All matches have a thirty-minute time limit and in case of a time limit draw, both teams are awarded one point, while a win earns a team two points. In case of a draw through a double countout, the match is declared a no contest with neither team being awarded a point. After all teams have faced each other,

148-463: A bye . The schedule can therefore be computed as though the dummy were an ordinary player, either fixed or rotating. Instead of rotating one position, any number relatively prime to ( n − 1 ) {\displaystyle (n-1)} will generate a complete schedule. The upper and lower rows can indicate home/away in sports, white/black in chess , etc.; to ensure fairness, this must alternate between rounds since competitor 1

222-464: A bye. If the number is even, an added player (ω) becomes the opponent. For an even number n {\displaystyle n} or an odd number n − 1 {\displaystyle n-1} of competitors, Schurig builds a table with n / 2 {\displaystyle n/2} vertical rows and n − 1 {\displaystyle n-1} horizontal rows. Then he populates it starting from

296-489: A certain number of wins or losses. The term round-robin is derived from the French term ruban ('ribbon'). Over time, the term became idiomized to robin . In a single round-robin schedule, each participant plays every other participant once. If each participant plays all others twice, this is frequently called a double round-robin . The term is rarely used when all participants play one another more than twice, and

370-411: A competitor to play the strongest opponents in a round robin in quick succession while others play them intermittently with weaker opposition. This asymmetry means that playing the same opponents is not necessarily completely equitable. There is also no scheduled showcase final match unless (by coincidence) two competitors meet in the last match of the tournament, with the result of that match determining

444-477: A competitor's chance of ultimate victory. Final records of participants are more accurate, in the sense that they represent the results over a longer period against the same opposition. The system is also better for ranking all participants, not just determining the winner. This is helpful to determine the final rank of all competitors, from strongest to weakest, for purposes of qualification for another stage or competition as well as for prize money. In team sports,

518-418: A loss to Jake Lee, Koji Iwamoto, and Nobe Bryant. At the time of his death, Aoki was scheduled to defend his title against Hikaru Sato on June 18. Despite his death, AJPW announced he would be recognized as champion until November 2019, allowing his 6 month defence clause to expire before crowning a new champion. On June 3, 2019, Aoki was killed in a motorcycle accident when he collided with the side wall around

592-489: A lower-placed qualifier is perceived to be easier than for a higher-placed one). Four pairs in the 2012 Olympics Women's doubles badminton , having qualified for the next round, were ejected from the competition for attempting to lose in the round robin stage to avoid compatriots and better ranked opponents. The round robin stage at the Olympics was a new introduction, and these potential problems were readily known prior to

666-437: A round in which players meets each other. For example, player 7 plays against player 11 in round 4. If a player meets itself, then this shows a bye or a game against player n. All games in a round constitutes a diagonal in the table. The above schedule can also be represented by a graph, as shown below: Both the graph and the schedule were reported by Édouard Lucas in as a recreational mathematics puzzle. Lucas, who describes

740-497: A round, a non-leftmost position (not including 1 {\displaystyle 1} ) can only be taken by competitors of a fixed distance. In round 1 {\displaystyle 1} of the example, in the second position competitor 2 {\displaystyle 2} plays against 13 {\displaystyle 13} , their distance is 2 {\displaystyle 2} . In round 2 {\displaystyle 2} , this position

814-540: A schedule where player 14 has a fixed position, and all other players are rotated counterclockwise n 2 {\displaystyle {\frac {n}{2}}} positions. This schedule is easily generated manually. To construct the next round, the last player, number 8 in the first round, moves to the head of the table, followed by player 9 against player 7, player 10 against 6, until player 1 against player 2. Arithmetically, this equates to adding n 2 {\displaystyle {\frac {n}{2}}} to

888-657: A shot at the GHC Junior Heavyweight Tag Team Championship , but were defeated by the champions, New Japan Pro Wrestling representatives Koji Kanemoto and Tiger Mask IV, on November 23, 2010. On December 24, 2010, Aoki and Naomichi Marufuji defeated Kanemoto and Tiger Mask IV to win the GHC Junior Heavyweight Tag Team Championship, Aoki's first title in Noah. Aoki and Marufuji were stripped of

962-619: A straight knockout system. The top one, two, or occasionally three teams in these groups then proceed to a straight knockout stage for the remainder of the tournament. In the circle of death it is possible that no champion emerges from a round-robin tournament, even if there is no draw, but most sports have tie-breaker systems which resolve this. Round-robins can suffer from being too long compared to other tournament types, and with later scheduled games potentially not having any substantial meaning. They may also require tie-breaking procedures. Swiss system tournaments attempt to combine elements of

1036-526: A table. In France this is called the Carousel -Berger system (Système Rutch-Berger). The schedule can also be used for "asynchronous" round-robin tournaments where all games take place at different times (for example, because there is only one venue). The games are played from left to right in each round, and from the first round to the last. When the number of competitors is even, this schedule performs well with respect to quality and fairness measures such as

1110-560: A tag team match. On July 5, following a mass exodus led by Keiji Mutoh , it was announced that Aoki, along with the rest of Burning, had signed an exclusive contract with All Japan. On October 29, Aoki and Suzuki quit Burning in order for Suzuki to challenge Kanemaru for the World Junior Heavyweight Championship . On November 21, Aoki and Suzuki, along with Kento Miyahara, joined Go Shiozaki's new Xceed stable. On January 26, 2014, Aoki and Suzuki lost

1184-416: A tournament of 16 teams can be completed in just 4 rounds (i.e. 15 matches) in a knockout format; a double elimination tournament format requires 30 (or 31) matches, but a round-robin would require 15 rounds (i.e. 120 matches) to finish if each competitor faces each other once. Other issues stem from the difference between the theoretical fairness of the round robin format and practice in a real event. Since

1258-758: A two time winner of the Global Junior Heavyweight Tag League and hold the GHC Junior Heavyweight Tag Team Championship twice during his 7 year run with the promotion. Aoki jumped to All Japan Pro Wrestling (AJPW) in December 2012 where he became the top star of the junior heavyweight division, winning the AJPW World Junior Heavyweight Championship four times and the All Asia Tag Team Championship 3 times. Aoki

1332-571: A variety of tiebreaker criteria. Frequently, pool stages within a wider tournament are conducted on a round-robin basis. Examples with single round-robin scheduling include the FIFA World Cup , UEFA European Football Championship , and UEFA Cup (2004–2009) in football, Super Rugby ( rugby union ) in the Southern Hemisphere during its past iterations as Super 12 and Super 14 (but not in its later 15- and 18-team formats),

1406-613: Is a simple algorithm to create a schedule for a round-robin tournament. All competitors are assigned to numbers, and then paired in the first round: Next, one of the competitors in the first or last column of the table is fixed (number one in this example) and the others rotated clockwise one position: This is repeated until when the next iteration would lead back to the initial pairings: With an even number n {\displaystyle n} of competitors this algorithm realizes every possible combination of them (equivalently, that all pairs realized are pairwise different). First,

1480-435: Is always on the first row. If, say, competitors 3 and 8 were unable to fulfil their fixture in the third round, it would need to be rescheduled outside the other rounds, since both competitors would already be facing other opponents in those rounds. More complex scheduling constraints may require more complex algorithms. This schedule is applied in chess and draughts tournaments of rapid games, where players physically move round

1554-691: Is even, then in each of ( n − 1 ) {\displaystyle (n-1)} rounds, n 2 {\displaystyle {\begin{matrix}{\frac {n}{2}}\end{matrix}}} games can be run concurrently, provided there exist sufficient resources (e.g. courts for a tennis tournament). If n {\displaystyle n} is odd, there will be n {\displaystyle n} rounds, each with n − 1 2 {\displaystyle {\begin{matrix}{\frac {n-1}{2}}\end{matrix}}} games, and one competitor having no game in that round. The circle method

1628-1054: Is held by competitors 14 {\displaystyle 14} and 12 {\displaystyle 12} , also having distance 2 {\displaystyle 2} , etc. Similarly, the next position ( 3 {\displaystyle 3} against 12 {\displaystyle 12} in round 1 {\displaystyle 1} , 2 {\displaystyle 2} against 11 {\displaystyle 11} in round 2 {\displaystyle 2} , etc.) can only hold distance- 4 {\displaystyle 4} competitors. For every k < n 2 {\displaystyle k<{\frac {n}{2}}} , there are exactly n − 1 {\displaystyle n-1} pairs of distance k {\displaystyle k} . There are n − 1 {\displaystyle n-1} rounds and they all realize one distance- k {\displaystyle k} pair at

1702-504: Is never used when one participant plays others an unequal number of times, as is the case in almost all of the major North American professional sports leagues. In the United Kingdom , a round-robin tournament has been called an American tournament in sports such as tennis or billiards which usually have single-elimination (or "knockout") tournaments, although this is now rarely done. A round-robin tournament with four players

1776-413: Is sometimes called "quad" or "foursome". In sports with a large number of competitive matches per season, double round-robins are common. Most association football leagues in the world are organized on a double round-robin basis, in which every team plays all others in its league once at home and once away. This system is also used in qualification for major tournaments such as the FIFA World Cup and

1850-408: Is the fairest way to determine the champion from among a known and fixed number of contestants. Each contestant, whether player or team, has equal chances against all other opponents because there is no prior seeding of contestants that will preclude a match between any given pair. The element of luck is seen to be reduced as compared to a knockout system since one or two bad performances need not ruin

1924-517: The 2013 Junior Hyper Tag League and earn another shot at Kanemoto and Tanaka. On April 25, Aoki and Suzuki defeated Kanemoto and Tanaka in a rematch to become the new All Asia Tag Team Champions. On May 11, Aoki made a one night return to Noah to take part in Kenta Kobashi's retirement event, Final Burning in Budokan , during which he and Suzuki defeated Kentaro Shiga and Tamon Honda in

1998-534: The 2014 Jr. Tag Battle of Glory . On March 27, 2015, Aoki lost the World Junior Heavyweight Championship to Kotaro Suzuki. On October 23, Aoki and Hikaru Sato won their second Jr. Tag Battle of Glory in a row by winning the round-robin tournament with a record of three wins and one loss. On January 1, 2016, Aoki was appointed the president of talent relations. On February 21, 2016, Aoki defeated tag team partner Hikaru Sato in

2072-574: The 2025 ICC Champions Trophy . In a more extreme example, the KBO League in baseball plays a 16-fold round robin, with each of the 10 teams playing each other 16 times for a total of 144 games per team. LIDOM (Baseball Winter League in the Dominican Republic) plays an 18-fold round robin as a semi final tournament between four classified teams. Group tournaments rankings usually go by number of matches won and drawn, with any of

2146-656: The Cricket World Cup along with Indian Premier League , major Twenty-20 Cricket tournament, and many American football college conferences , such as the Conference USA (which currently has 9 members). The group phases of the UEFA club competitions and Copa Libertadores are contested as a double round-robin, as are most basketball leagues outside the United States, including the regular season of

2220-536: The EuroLeague (as well as its former Top 16 phase); the United Football League has used a double round-robin for both its 2009 and 2010 seasons. Season ending tennis tournaments also use a round robin format prior to the semi on stages. The champion in a round-robin tournament is the contestant that wins the most games, except when draws are possible. In theory, a round-robin tournament

2294-491: The 10 Match series begun. His tenth and final match in the Shining Magic 10 Match series took place on February 28, 2010, which saw Aoki lose to Minoru Suzuki ending the series with one victory and nine defeats. On October 30, 2010, Aoki and Kenta defeated Roderick Strong and Eddie Edwards in the finals of a tournament to win the 2010 Nippon TV Cup Junior Heavyweight Tag League . As a result, Aoki and Kenta received

2368-410: The 2009 Super J-Cup . Aoki did not make it past the first round as he was defeated by Prince Devitt. On December 23, 2007, Aoki took on a "10 match challenge" designed to push him to the limit and earn experience against very experienced wrestlers. The first match was against his mentor Jun Akiyama which he lost. The match series was called the "Shining Magic 10 Match Series" and would stretch out over

2442-549: The All Asia Tag Team Championship to Atsushi Onita and Masanobu Fuchi . Aoki and Sato regained the title from Onita and Fuchi on June 20, 2017. They lost the title to Black Tiger VII and Taka Michinoku on August 27. In early 2018, still using his birth name, Aoki began working under a mask and regained the World Junior Heavyweight Championship from Tajiri on February 3 in Yokohama. Aoki held

2516-472: The All Asia Tag Team Championship to former Burning stablemates Jun Akiyama and Yoshinobu Kanemaru. On February 5, Aoki announced he was quitting Xceed to go solo. On May 29, Aoki defeated Último Dragón to become the new World Junior Heavyweight Champion. On July 27, Aoki joined the Evolution stable, after a successful title defense against one of its members, Hikaru Sato . In October, Aoki and Sato won

2590-514: The Mauritius Cup. Aoki teamed up with Akihiko Ito to participate in the 2008 Nippon TV Cup Junior Heavyweight Tag League . The team earned only three points, one point more than Aoki's previous Nippon TV Cup league as the team only managed to defeat Kento Miyahara and Naomichi Marufuji and wrestle to a time-limit draw against Eddie Edwards and Ricky Marvin . He was invited to be part of New Japan Pro-Wrestling 's (NJPW) 2009 Best of

2664-852: The National Open Wrestling Championship in the 69 kg weight class. In 2005, he applied to join the Pro Wrestling Noah dojo and was accepted. Aoki began training under Jun Akiyama in the Pro Wrestling Noah Dojo in May 2005. His professional wrestling debut came on December 24, 2005, during NOAH's NOAHful Gift in Differ '05 teaming up with Yoshiniro Ota, losing to NOAH founder Mitsuharu Misawa and Japanese wrestling legend Akira Taue . Aoki spent most of 2006 gaining hard earned experience in

2738-669: The Super Juniors tournament. Aoki earned eight points, ending in second place in "Block A" with victories over AKIRA , Black Tiger V , Jado and Milano Collection A.T. and only losing to "Block A" winner Prince Devitt (Block winner) and Tiger Mask IV . In the semi-final of the tournament he was defeated by eventual tournament winner Koji Kanemoto . Unlike the 2007 and 2008 version of the Nippon TV Cup Junior Heavyweight Tag League Aoki's 2009 participating alongside Kota Ibushi

2812-446: The algorithm obviously realizes every pair of competitors if one of them equals 1 {\displaystyle 1} (the non-moving competitor). Next, for pairs of non- 1 {\displaystyle 1} competitors, let their distance be the number k < n 2 {\displaystyle k<{\frac {n}{2}}} of times the rotation has to be carried out in order that one competitor arrives at

2886-540: The amount of rest between games. On the other hand, when the number of competitors is odd, it does not perform so well and a different schedule is superior with respect to these measures. Alternatively Berger tables, named after the Austrian chess master Johann Berger , are widely used in the planning of tournaments. Berger published the pairing tables in his two Schach-Jahrbücher (Chess Annals), with due reference to its inventor Richard Schurig. This constitutes

2960-491: The championship against Beer Money, Inc. ( Robert Roode and James Storm ), La Hermandad 187 ( Nicho el Millonario and Joe Líder ) and Los Maniacos ( Silver King and Último Gladiador ) in a four-way elimination match; they were the first team eliminated when Líder pinned Shiozaki, which meant that they lost the AAA Tag Team championship 14 days after winning it. Los Maniacos (Silver Cain and Último Gladiador) won

3034-435: The championship. A notable instance of such an event was the 1950 FIFA World Cup match between Uruguay and Brazil . Further issues arise where a round-robin is used as a qualifying round within a larger tournament. A competitor already qualified for the next stage before its last game may either not try hard (in order to conserve resources for the next phase) or even deliberately lose (if the scheduled next-phase opponent for

3108-581: The continental tournaments (e.g. UEFA European Championship , CONCACAF Gold Cup , AFC Asian Cup , CONMEBOL Copa América and CAF Cup of Nations ). There are also round-robin cricket , bridge , chess , draughts , go , ice hockey , curling , and Scrabble tournaments. The World Chess Championship decided in 2005 and in 2007 on an eight-player double round-robin tournament where each player faces every other player once as white and once as black. There has been several major international cricket tournaments held in this format including ICC events, including

3182-461: The excursion lasted. Following his return to NOAH he teamed up with American Rocky Romero to participate in the 2007 Nippon TV Cup Junior Heavyweight Tag League . The team ended up with just two points, winning only one match out of five when the team defeated Bryan Danielson and Davey Richards . On September 3, 2007, Aoki teamed up with Ippei Ota for a match at an AAA / Pro Wrestling Noah co-promoted show called TripleSEM . The team wrestled in

3256-485: The expressway of Kitanomaru Park in the Chiyoda ward of Tokyo. He was 41 years old. In a press conference in the days after the accident, All Japan Pro Wrestling president at the time, Jun Akiyama announced that the World Junior Heavyweight Championship was to be vacated at the end of the title's mandatory defence period, allowing Aoki to reign as de facto champion in honor of his contributions until late 2019, when

3330-446: The finals to win the 2016 Jr. Battle of Glory and the vacant World Junior Heavyweight Championship. He went on to lose the title to Sato on June 19. On July 24, Aoki and Sato defeated Isami Kodaka and Yuko Miyamoto to win the All Asia Tag Team Championship. On November 17, Aoki and Sato won their third Jr. Tag Battle of Glory in a row by defeating Soma Takao and Yuma Aoyagi in a playoff match. On November 27, Aoki and Sato lost

3404-621: The first "World's Strongest Junior Tag League", a junior heavyweight version of the World's Strongest Tag Determination League . The tournament took place over eleven shows between September 8 and 22. The day after winning the tournament, Jimmy Yang and Kaz Hayashi went on to unsuccessfully challenge Arashi and Nobutaka Araya for the All Asia Tag Team Championship . After a four-year break, All Japan Pro Wrestling held its first Junior Tag League over nine shows between February 25 and March 10, 2006. After no Junior Tag League took place in 2007,

3478-522: The match and the championship. On January 26, 2013, Aoki, Go Shiozaki, Jun Akiyama, Kotaro Suzuki and Yoshinobu Kanemaru , all of whom had quit Noah at the same time, announced that they had joined All Japan Pro Wrestling , forming the " Burning " stable. Aoki and Suzuki received their first shot at the All Asia Tag Team Championship on March 17, but were defeated by the defending champions, Koji Kanemoto and Minoru Tanaka . On April 7, Aoki and Suzuki defeated Hikaru Sato and Hiroshi Yamato to win

3552-403: The method as simple and ingenious , attributes the solution to Felix Walecki, a teacher at Lycée Condorcet . Lucas also included an alternative solution by means of a sliding puzzle . To easily remember this method, the following mnemonic can be used. Starting from the first round, the next round is constructed: and then, If the number of players is odd, the player in the first venue gets

3626-562: The next two and a half years. In his second match he defeated Davey Richards, but went on to lose against Kenta, Bryan Danielson, Yoshinari Ogawa and Kaz Hayashi . The Seventh match in the series took place on November 14, 2008, and saw Aoki lose to Yoshinobu Kanemaru. In his eight Shining Magic 10 Match Aoki lost to Junior Heavyweight legend Jyushin Thunder Liger . In his penultimate Sining Magic match Atsushi Aoki lost to Naomich Marufuji on December 6, 2009, almost two years after

3700-496: The position the other had. In the example given ( n = 14 {\displaystyle n=14} ), 2 {\displaystyle 2} has distance 1 {\displaystyle 1} to 3 {\displaystyle 3} and to 14 {\displaystyle 14} and it has distance 6 {\displaystyle 6} to 8 {\displaystyle 8} and to 9 {\displaystyle 9} . In

The winners of the tournament earned a spot in the 2014 World's Strongest Tag Determination League . The 2015 Jr. Tag Battle of Glory took place over eight shows between October 12 and 23. Último Dragón and Yoshinobu Kanemaru entered the tournament as the reigning All Asia Tag Team Champions , but relinquished

3922-554: The promotion, after refusing to re-sign following the firing of Kenta Kobashi . In his final match for the promotion on December 24, Aoki was defeated by Mr. Christmas, portrayed by his trainer Jun Akiyama. On May 23, 2010, Aoki teamed up with Go Shiozaki to defeat the team of Takeshi Morishima and Taiji Ishimori to win the AAA World Tag Team Championship , which was Aoki's first wrestling title. At Triplemanía XVIII , Aoki and Shiozaki defended

3996-399: The reigning champions. Hikaru Sato holds the record for most Junior Tag League wins with five. Sato and Atsushi Aoki are the only team to have won the tournament more than once, having won it in 2014 , 2015 and 2016 . In 1984, All Japan Pro Wrestling held the "International Junior Heavyweight Tag Team League" between August 30 and September 12. In 2002, All Japan Pro Wrestling held

4070-528: The ring, mostly on the losing side of matches. He would also make appearances for other Japanese promotions such as Zero-1 MAX and Dragon Gate . A month later Aoki undertook a "learning excursion" to Europe where he wrestled for such promotions as Real Quality Wrestling and International Pro Wrestling: United Kingdom in the United Kingdom and Westside Xtreme Wrestling in Germany for the two months

4144-406: The round-robin and elimination formats, to provide a worthy champion using fewer rounds than a round-robin, while allowing draws and losses. The main disadvantage of a round robin tournament is the time needed to complete it. Unlike a knockout tournament where half of the participants are eliminated after each round, a round robin requires one round less than the number of participants. For instance,

4218-525: The round-robin major league champions are generally regarded as the "best" team in the land, rather than the cup winners, whose tournaments usually follow a single-elimination format. Moreover, in tournaments such as the FIFA or ICC World Cups, a first round stage consisting of a number of mini round robins between groups of 4 teams guards against the possibility of a team travelling possibly thousands of miles only to be eliminated after just one poor performance in

4292-408: The same position. Clearly, these pairs are pairwise different. The conclusion is that every distance- k {\displaystyle k} pair is realized. This holds for every k {\displaystyle k} , hence, every pair is realized. If there are an odd number of competitors, a dummy competitor can be added, whose scheduled opponent in a given round does not play and has

4366-608: The teams. This famously happened during the 1994 FIFA World Cup Group E , where all four teams finished with a record of one win, one draw, and one loss. This phenomenon is analogous to the Condorcet paradox in voting theory. If n {\displaystyle n} is the number of competitors, a pure round robin tournament requires n 2 ( n − 1 ) {\displaystyle {\begin{matrix}{\frac {n}{2}}\end{matrix}}(n-1)} games. If n {\displaystyle n}

4440-505: The third match of the night and lost to AAA representatives Real Fuerza Aerea ( Laredo Kid and Super Fly ) in 08:15. In November, 2007 Aoki took part in NOAH's Mauritius Cup tournament, earning 8 points in total by defeating Ippei Ota, Tsutomu Hirayanagi and Akihiko Ito while wrestling to a draw against Shuhei Taniguchi and Taiji Ishimori . Despite not losing a single match in the tournament Shuhei Taniguchi managed to score 9 points to take

4514-437: The title after losing to Isami Kodaka and Yuko Miyamoto in their opening match. The 2016 Jr. Tag Battle of Glory took place over five shows between November 12 and 17. The 2017 Jr. Tag Battle of Glory took place over five shows between November 3 and 9. The 2018 Junior Tag League took place over ten shows between August 3 and 25. The 2019 Junior Tag League took place over eight shows between July 17 and 28. Atsushi Aoki

4588-504: The title on April 29, 2011, after Marufuji suffered an injury. On July 30, Aoki and Kotaro Suzuki defeated Kenta and Yoshinobu Kanemaru to win the 2011 NTV G+ Cup Junior Heavyweight Tag League , making both of them two-time winners of the tournament. On October 16, 2011, Aoki and Suzuki defeated Kenta and Kanemaru to win the GHC Junior Heavyweight Tag Team Championship. They lost the title to Ricky Marvin and Super Crazy on July 22, 2012. On December 19, Noah announced that Aoki would be leaving

4662-541: The title until August, when he dropped it to Koji Iwamoto. In April 2019, Aoki competed in the Champion Carnival once again as a last minute replacement for Kengo Mashimo . Aoki competed in A Block and managed to finish with 8 points, but was unable to advance to the final. Aoki regained the World Junior Heavyweight Championship for the fourth time on May 20, 2019, defeating Iwamoto. His last match took place on June 2, teaming with Hikaru Sato and Yusuke Okada in

4736-538: The top left corner by repeating the sequence of numbers from 1 up to n − 1 {\displaystyle n-1} . Here is an example table for 7 or 8 competitors: Atsushi Aoki Atsushi Aoki ( 青木 篤志 , Aoki Atsushi , September 25, 1977 – June 3, 2019) was a Japanese professional wrestler who worked for All Japan Pro Wrestling (AJPW) as a wrestler, president of talent relations and head trainer at their dojo. Aoki began his career in Pro Wrestling Noah in 2005, where he went on to become

4810-445: The top two teams move onto the finals to determine the winner of the tournament. Rankings in the tournament are not determined by head-to-head matches and in the event of more than two teams finishing clear of the other teams, extra matches will be held to determine the finalists. Usually, the winners of the tournament earn themselves a shot at All Japan's secondary tag team championship, the All Asia Tag Team Championship , if not already

4884-428: The tournament returned in early 2008, held over seven shows between March 12 and 23. The 2009 Junior Tag League took place over eight shows between April 17 and 29. The 2010 Junior Tag League took place over seven shows between April 18 and May 2. The 2011 Junior Tag League took place over eight shows between April 17 and 30. The 2012 Junior Tag League took place over six shows between April 1 and 14. The winners of

4958-481: The tournament, Kaz Hayashi and Shuji Kondo , went on to unsuccessfully challenge Daisuke Sekimoto and Yuji Okabayashi for the All Asia Tag Team Championship on May 27. In 2013, All Japan Pro Wrestling renamed the Junior Tag League the "Junior Hyper Tag League", following in the footsteps of the singles Junior League , which had been renamed "Junior Hyper League" the previous summer. The tournament

5032-435: The tournament; changes were made prior to the next Olympics to prevent a repeat of these events. Another disadvantage, especially in smaller round-robins, is the "circle of death", where teams cannot be separated on a head-to-head record. In a three-team round-robin, where A defeats B, B defeats C, and C defeats A, all three competitors will have a record of one win and one loss, and a tiebreaker will need to be used to separate

5106-451: The victor is gradually arrived at through multiple rounds of play, teams who perform poorly, who might have been quickly eliminated from title contention, are forced to play out their remaining games. Thus games are played late in the competition between competitors with no remaining chance of success.
