NHK Cup (shogi)

The NHK Cup (shogi), or as it is officially known the NHK Cup TV Shogi Tournament (NHK杯テレビ将棋トーナメント enu eichi kei hai terebi shōgi tōnamento)[1] is a professional shogi tournament organized by the Japan Shogi Association (日本将棋連盟 nihon shōgi renmei), or JSA,[2] and sponsored by the Japan's public broadcaster NHK (日本放送協会 nippon hōsō kyōkai).[3]

History

Formerly known as the NHK Cup Competition Shogi Tournament (NHK杯争奪将棋トーナメント enu eichi kei hai sōdatsu tōnamento), the 1st NHK Cup was held in 1951 with eight shogi professionals (棋士 kishi)[lower-alpha 1] The winner was Yoshio Kimura, who held the Meijin title at the time. Prior to 1962, the tournament was broadcast only on the radio, but starting with the 12th NHK Cup (1962), the tournament moved to television.[4] The 26th NHK Cup (1976) was the first to be broadcast in color.[5]

Up until and including the 15th NHK Cup (1965), only Class A professionals[lower-alpha 2] were allowed to participate. When the number of players was increased from 8 to 16 for the 16th NHK Cup (1966), the tournament became open to other professionals as well. The number of players was increased again from 16 to 26 for the 27th NHK Cup (1977) and to its current level of 50 for the 31st NHK Cup (1981). In addition, the preliminary tournaments also started with the 31st NHK Cup.

Women's professionals (女流棋士 jōryū kishi)[lower-alpha 3] were allowed to participate for the first time in the 43rd NHK Cup (1993). Hiroe Nakai was the first woman to participate in the tournament. To commemorate of tournament's 60th anniversary, the number of players was increased to 51 players for the 60th NHK Cup (2010) to allow a second woman professional to participate.[8] The number of players returned to 50 for the 61st NHK Cup (2011).

Although tournament games are typically recorded in advance in a closed studio for broadcast at a later date, the final of the 45th NHK Cup (1995) was the first to be held before a studio audience. This was repeated again for the final of the 49th NHK Cup (1999). The final for the 57th NHK Cup (2007) was the first to be broadcast live.

To commemorate the tournament's 50th anniversary, the final of the 50th NHK Cup (2000) was held at the Kansai Shogi Kaikan (関西将棋会館 kansai shōgi kaikan). This was the first time that a final was held outside of Tokyo.

The tournament returned to radio in 2010, when the final of 60th NHK Cup was also broadcast on the NHK Radio 1.[9] The finals for both the 61st and 62nd NHK Cups were also broadcast on NHK Radio 1.[10][11] In addition, each tournament game can also be viewed online for a short period of time after it has been broadcast and for a small fee using the NHK On Demand service.[12] This video-on-demand (VOD) service, however, is currently only available to those living in Japan.[13] In April 2014, NHK discontinued this service for the 64th NHK Cup.[14]

Format

The tournament is actually made up of two parts: the main tournament, and preliminary tournaments. The main tournament is a 6-round single elimination tournament in which 50 players (divided into two 25-player blocks: "Block A" and "Block B") compete for the title of "NHK Cup Champion". The first 4 rounds determine the four players who will meet in the two semifinals to determine the winner of each block; The two block winners then meet in the final to determine the overall tournament winner. All of the games played in the main tournament are televised.[4]

Participants

A total of 50 players complete in the main tournament: 49 professionals and one women's professional.[15] Of the 50 players, 32 are seeded and 18 are preliminary tournament winners.[4] Seeded players are determined based upon their results as of December 31 of the previous year. The criteria for selecting seeded players are as follows:[16]

  1. The winner, runner-up and two losing semifinalists from the previous year's tournament. (These players are guaranteed not to be paired with each other until the semifinal round (round 5))
  2. Current titleholders of the seven main titles: Meijin, Ryūō, Kiō, ōshō, ōza, ōi and Kisei
  3. Lifetime title holders or those who have qualified for such titles (including "Lifetime NHK Cup champions") and players in either Class A or Class B1.
  4. Winners of other tournaments during the previous year.
  5. One reigning women's title holder.
  6. Players who had performed at an exceptionally high level during the previous year. Typically, these are players who ranked at the top in terms of the number of games played, number of games won, and winning percentage on the JSA's year end ranking of players. (The actual number varies depending upon the number of players selected according to Nos. 1 through 4 above)

Among the seeded players, fourteen are directly seeded into round 2 and, thus, only need to win five games to win the tournament. These include the defending NHK Cup Champion, the previous year's runner-up, the previous year's other two semifinalists, and all of the players in Class A as of December 31 of the previous year. Occasionally other players are also seeded into round 2 in order to complete the fourteen if necessary; This often happens when one or more of the Class A players is also one of the previous year's tournament's semifinalists or a reigning major title holder.

Professionals who do not qualify as one of the aforementioned seeds must win a preliminary tournament in order to advance to the main tournament. A total of eighteen 3-round single elimination preliminary tournaments are held in the Kanto and Kansai regions of Japan during the February before the tournament: twelve are held at the Tokyo Shogi Kaikan (東京将棋会館 tōkyō shōgi kaikan) and six are held at the Kansai Shogi Kaikan. The preliminary tournaments are one-day tournaments open and, depending upon the number of players playing (typically seven to eight players per tournament), the winner must win either two or three consecutive games to win the tournament.[4]

Brackets

Both the preliminaries and the main tournament use a bracket system. In the main tournament, there are 6 rounds in each bracket. In round 1, there are 9 games played in each bracket and the winners of those games advance to round 2. In round 2, there are 8 games played in each bracket and the winners advance to round 3. In round 3, the remaining 8 players in each bracket compete for the right to advance to the quarterfinals. The quarterfinalists then play each other for a spot in the semifinals; and finally, the last 4 players face each other for a spot in the final. A total of 47 games are played in a tournament; However, this may end up being more if there are any games replayed because they ended in "repetition" (千日手 sen'nichite) or "impasse" (持将棋 jishōgi).

Time controls

The NHK Cup is a "quick play" (早指し hayazashi) tournament with time controls that are quite short in comparison to those of the major shogi titles. The entire game usually lasts no more than ninety minutes whereas a major title game often spans two days, and a single move can take hours. An analog chess clock is used to keep track of each player's first time control. Unlike professional chess tournaments, professional shogi players do not have to manage their own clocks or keep the game score. An official "game score keeper" (記録係 kiroku gakari), typically a shōreikai member, keeps the official record of the game and keeps track of each player's time. [lower-alpha 4] In addition to the official game score keeper, there is also an "official game score reader" (棋譜読み上げ kifū yomiage) who announces each move after it is played as well as the total number of moves played and the final result once the game has finished. The official game score reader for main tournament games is typically a women's professional.

Preliminary tournaments

The first time control (持ち時間 mochi jikan) is 20 minutes per player followed by a byōyomi time control of 30 seconds per move. A player in byōyomi who fails to make their move within 30 seconds loses the game. The remaining seconds of byōyomi are counted down by the official game score keeper.[18]

Main tournament (televised games)

The first time control is 10 minutes per player. Once this 10 minutes has been used up, a second time control of 10 one-minute periods of "thinking time" (考慮時間 kōryō jikan) starts.[lower-alpha 5] When a player has used up all of their thinking time periods, a final byōyomi time control of 30 seconds per move begins.[18][19] The official game score keeper counts down the remaining seconds of a thinking time period, announces when a player has used up one of these periods as well as the number of periods remaining, and counts down the remaining seconds of the byōyomi time control.

Tournament records

Lifetime NHK Cup Champions

Players who win the tournament a total of 10 times qualify for the title "Lifetime NHK Cup Champion" and as such are granted a lifetime seed into all future NHK Cups. To date, only Yoshiharu Habu has qualified to be a Lifetime NHK Cup Champion[lower-alpha 7] Habu has won the tournament a total of 10 times. The next closest is Yasuharu Ōyama (deceased) who won the tournament 8 times,[4] and the next closest currently active player is Hifumi Katō who has won the tournament 7 times.[4] Habu qualified for the title by beating Akira Watanabe to win the 61st NHK Cup (2011) on March 18, 2012.[21][23]

Preliminaries

Since 2005, the women's professional seed has been determined by a playoff between the reigning women's title holders.[4] There are currently six major women's titles [lower-alpha 11] and in cases where there are three or more different title holders, the playoff takes the form of a tournament. Starting with the 55th NHK Cup (2005), women's title holders who are also members of the shōreikai became ineligible to compete for this seed. The women's preliminaries are recorded for broadcast at a later date, typically on the Sunday between the second semifinal game and the final. The time controls for the final are the same as the time controls for main tournament games. Winner's names are in bold.

Broadcasts

Television

The tournament lasts roughly one year from April to the following March. Tournament games are televised each Sunday from 10:30 am to 12:00 pm Japan Standard Time (JST) on NHK Educational TV (NHK-E)[1] and live commentary and analysis is provided by two commentators (shogi professionals): A women's professional who serves as the tournament's host and a professional who serves as the guest display board analyst.

The games are recorded in advance for broadcast at a later date. Before each game, the host briefly interviews each player and asks them about the upcoming game. The players typically sit across from each other seiza-style on zabutons placed on tatami mats in a Japanese-style room (the main studio set) while the two commentators stand before a display board in another studio. Although the player who moves first sits on the left (from the TV audience's perspective), the higher ranked player still takes the ōshō (king general) regardless of the result of the piece toss. Sitting parallel to board at a small table are the official time keeper and the official game score reader. Multiple cameras are used to provide overhead shots of the board, particularly when a player makes a move, wide shots or close-ups of both players when thinking and of the two commentators.[4] In addition, special single-character shogi pieces are used so that they can easily be seen by television audience. Once a game has finished, the two commentators join the two players on the main set and post-game analysis takes place broadcast time permitting.

Women's professionals began serving as tournament hosts for the 41st NHK Cup (1991) and usually serve in such a capacity for three tournaments (i.e., three years) before being replaced. The following table shows the hosts since 1991.

The tournament final is hosted by an NHK announcer. The two finalists are joined in a separate studio by the NHK announcer, the tournament's women's professional host and a guest analyst (or analysts) for interviews and some small talk. Each of the finalists is asked to comment on their play throughout the tournament and the upcoming final. The women's professional host and the guest analyst(s) are also asked to give their impressions of tournament and thoughts on the final. Everyone gathers again in the same studio after the final has finished for the awards ceremony where a NHK executive presents the winner with the NHK Cup (trophy) and a certificate, and the runner-up with a certificate. The NHK announcer then conducts some final interviews, and briefly previews the next NHK Cup before the broadcast ends.

Radio

From the 1st NHK Cup (1951) until the 11th NHK Cup (1961), the tournament was exclusively broadcast on NHK Radio. The radio broadcasts stopped, however, once the tournament switched to television in 1962 for the 12th NHK Cup.[4]

The tournament returned to radio in 2011 when the final of the 60th NHK Cup was broadcast on NHK-1 Radio in honor of the 60th anniversary of the tournament. The program was hosted by an NHK announcer and commentary was provided by 3 professionals. NHK also created a website people could not only listen to the audio commentary, but could also follow the moves online. Even though the broadcast was not live, it proved to be fairly popular so NHK also did the same for the finals of both the 61st and 62nd NHK Cups as well. The player listed first was sente, and the winner's name is in bold.

Notable events

Habu beats four Meijins

In the 38th NHK Cup (1988), 18-year-old Yoshiharu Habu (at the time only a 5 dan), beat 3 former Meijin and the reigning Meijin in consecutive games on the way to his first NHK Cup championship. He defeated former Meijin Yasuharu Ōyama in round 3, former Meijin Hifumi Katō in the quarterfinals, reigning Meijin Kōji Tanigawa in the semifinals and former Meijin Makoto Nakahara in the finals.[70][71]

Nakai's wins

Hiroe Nakai became the first women's professional to win a NHK Cup game. She won her round 1 game of the 53rd NHK Cup (2003) against Mamoru Hatakeyama [33][34] and then in round 2 won against Teruichi Aono (who was in Class A at the time).[72] She lost in round 3 to Makoto Nakahara.[33][34] The following year Nakai also qualified for the 54th NHK Cup (2004) and continued her high level of play by beating Shūji Satō in round 1.[35][36] In round 2, Nakai faced Yasumitsu Satō who was the reigning Kisei title holder. Nakai obtained an advantageous position against Satō, but was unable to convert it into a win.[35][36] Nakai is still the only women's professional to have won a NHK Cup game.[73]

Same final four

The four semifinalists of the 59th NHK Cup (2009) were Yoshiharu Habu, Tetsurō Itadani, Tadahisa Maruyama and Akira Watanabe. Habu beat Maruyama in one semifinal and Itodani beat Watanabe in the other; Habu then beat Itodani in the final.[46][74] The next year in the 60th NHK Cup (2010), the same four players also made it to the semifinals. This time Habu beat Watanabe and Itodani beat Maruyama to make it to the finals where Habu once again beat Itodani to win the championship.[8][75]

Disqualifications

In Round 3 of the 46th NHK Cup (1996), Kenji Kobayashi lost on time to Nobuyuki Yashiki when he failed to complete his move within 30 seconds during byōyomi. Kobayashi picked up one of his pieces to make a move only to realize that said move would allow Yashiki to mate in one. Kobayashi tried to return the piece he was holding back to its original square and make a different move, but was unable to do so before the official time keeper for the game Hirotaka Nozuki (a Shōreikai 3 dan at the time) had counted to 30 and the time is up buzzer sounded. This is the only time that a player has lost a NHK Cup game on time.[76]

Takahiro Toyokawa (6 dan at the time) in round 1 of the 54th NHK Cup (2004),[77] Ayumu Matsuo (5 dan at the time) in round 1 of the 55th NHK Cup (2005) and Takanori Hashimoto (8 dan at the time) in the semifinals of the 64th NHK Cup (2014)[78] each lost games for making an illegal move called nifu.[79]

Two sen'nichite

In the 61st NHK Cup (2011), the Round 1 game between Takuya Nagase (sente) and Yasumitsu Satō (gote) ended in sen'nichite. Sente and gote were switched and the game was replayed. The second game also ended in sen'nichite. Sente and gote were switched again and a third game was played between the two which Nagase won.

Student vs. teacher

A young amateur player aspiring to become a professional typically asks a more experienced professional to formally become their sponsor (i.e., teacher/mentor) and help them through the process. In some cases, the "student" may even decide to go live with their "teacher" and family. There have been two occasions in NHK Cup play where a student has played their teacher, and on both occasions the student won: Tatsuya Sugai beat Keita Inoue in round 2 of the 61st NHK Cup (2011) and Daisuke Nakagawa beat Kunio Yonenaga in quarterfinals of the 45th NHK Cup (1995).

Notes

  1. ↑ The word kishi refers to shogi players officially awarded professional status by the JSA. Only amateurs strong enough to join and graduate from the JSA's Apprentice professional training school (奨励会 shōreikai) are awarded kishi status and the rank of professional 4 dan.
  2. ↑ Most JSA professionals compete in "ranking leagues" (順位戦 jun'isen). Performance in these leagues impacts the type of tournaments a professional can compete in as well as the salary and other monies (e.g., appearance fees, match fees, etc.) they receive from the JSA and others. There are five ranking leagues, or classes and games are held from June to March. Class A is the top class and the winner earns the right to challenge the reigning Meijin in the next Meijin title match. Professionals in classes B1, B2, C1 and C2 not only compete for promotion to the next highest class, but also to avoid demotion to the next lowest class. Professionals demoted from Class C2 become free class (フリークラス furīkurasu) professionals and must satisfy certain conditions before being allowed to rejoin Class C2. Failure to do so often leads to retirement.
  3. ↑ Women's professional ranks and status are different from those granted to professionals. Women's professional are recognized by the JSA, but they are only granted kishi status upon completion of the shōreikai. To date, there have been women (including some currently active women's professionals) who have successfully qualified for the shōreikai, but so far not one has successfully graduated. Only three women have made it as far as 1 dan in the shōrekai[6] and of those three only one has made it as far as 3 dan.[7]
  4. ↑ The official game score keeper also performs the "piece toss" (振り駒 furigoma) prior to the game to determine the "player who moves first" (先手 sente).[17]
  5. ↑ Each player is given 30 seconds to make a move. If a player makes a move within 30 seconds, no thinking time periods are used. If, however, the player takes more than 30 seconds to make a move, a thinking time period begins and the player will then have 1 minute (more specifically 59 seconds) to make a move before entering the next thinking time period. This process is repeated until the player has used all 10 thinking time periods.
  6. ↑ Gote (後手) refers to the "player who moves second".
  7. ↑ Although lifetime titles in professional shogi are, in principle, only officially awarded to those who qualify upon their retirement or death, it is not usual for those still active to be referred to by their titles as a sign of respect. Unlike other lifetime titles, however, the Lifetime NHK Cup Champion title is officially awarded after qualification regardless of whether the player is still active.
  8. ↑ For the traditional Japanese naming order please see Japanese names in English and Western languages
  9. ↑ The JSA does not, in general, use calendar years to identify it's tournaments. It uses ordinal numbers and the counter words kai (回) or ki (期) instead to refer to a tournament by the number of "times" or "periods" it has been held to date. For example, the tournament that began in April 2013 and ended in March 2014, is officially referred to as the 63rd NHK Cup TV Shogi Tournament" because it was the 63rd time the tournament had been held. Winners of tournaments are referred to in a similar fashion, e.g., the winner of the 2013-2014 tournament is called the "63rd NHK Cup Champion".
  10. ↑ For example, a "(2)" next to a winner's name means that this was the second time they won the tournament.
  11. ↑ the Women's Meijin, the Women's ōi, the Women's ōshō, the Kurashiki Tōka, the Mynavi Women's Open (established in 2007) and the Women's ōza (established in 2011).
  12. ↑ Remaining women's titleholders ineligible because they were shōreikai members: Kana Satomi 3 Crown (Women's Meijin, Kurashiki Tōka, Women's ōshō) and Momoko Katō (Women's ōza).
  13. ↑ Remaining women's titleholders ineligible because they were shōreikai members: Kana Satomi 4 Crown (Women's Meijin, Kurashiki Tōka, Women's ōshō, Women's ōi) and Momoko Katō (Women's ōza).
  14. ↑ Remaining women's titleholder ineligible because she was a shōreikai member: Kana Satomi 3 Crown (Women's Meijin, Mynavi Open and Women's ōza)
  15. ↑ Remaining women's titleholders ineligible because they were shōreikai members: Kana Satomi 3 Crown (Women's Meijin, Kurashiki Tōka, Women's ōshō, Women's ōi) and Momoko Katō (Mynavi Open and Women's ōza)
  16. ↑ All of the major titles were held by two women: Katō and Kana Satomi 4 Crown (Women's Meijin, Kurashiki Tōka, Women's ōshō, Women's ōi) . Katō and Satomi are shōreikai members and in past years would have been ineligible to participate, but the method for determining the women's entry for the 66th NHK Cup was changed from playoff to Japan Shogi Association recommendation.
