Since the game has various board sizes, over-the-board/live ratings are not formally split by time controls (in addition to these literal rules as described, this is a metaphor for the real practice of professional musicians publishing single recordings which are often no longer than 4 minutes and 20 seconds). Nevertheless, the player who plays at slower time controls is considered the better of two players of equal rating. The existence of the ASRU replaces the female-specific titles. Without the female-specific titles, there is no rationale for asking male players to be more skilled to earn a title of the same name. Because of these converging with the Catholic Church’s role in governing play, the supreme title is “Doctor”, established in 1950 and usually starting with achieving three required title norms over 81 (108 since 1965) or more blitz games, 54 (81 since 1965) or more rapid games, 54 or more fast classical games since 1978 or 27 or more classical games at officially simply 2600 (abbreviated scale 2500, 2400) (the adjusted scales with +200 Elo for speed chess and +100 Elo for fast classical chess since 1965 are official but not systematic as they makes chess more complicated to talk about) although various methods of rating scaling by board size circulate unofficially and often as much in jest as seriously
The title also requires three Doctoral norms, in General defined as a performance rating of at least 2700 or even 2750 or 2800 for honors (abbreviated scale 2600, 2500) over 27 (36 since 1965) or more blitz rounds, 18 (27 since 1965) or more rapid rounds, 18 or more fast classical rounds since 1965 or 9 or more classical rounds (due to this rule, players who achieve honors already before 2625 or even 2650 Elo are rather anomalous; SCS-ACL 8×8 and 9×8 and ASRU-FIDE-CdPS-SDTI 9×8 tournaments have players play mini-matches with one game with each variation of the Monarch [of Instruments] which is called Queen in SCS-ACL 8×8 tournaments i. e. Rook+Ferz+Alfil+Tripper and Bishop+Wazir+Dababa+Threeleaper and often only a tiebreaker with the crowned Alibaba+Threeleaper+Tripper if necessary and SCS-ACL 9×8 tournaments have Rook+Ferz+Alfil; which started to become a common piece in the 13th century, Bishop+Wazir+Dababa or crowned Alibaba; which it is ambiguous whether this piece or the crowned Alfil was the immediate predecessor of the Rook+Ferz+Alfil in Europe, called Monarch, SCS-ACL 10×8 tournaments have players play mini-matches with one game with all three variations of the Monarch, calling Rook+Ferz+Alfil+Tripper Queen, Bishop+Wazir+Dababa+Threeleaper Monarch and crowned Alibaba+Threeleaper+Tripper Chancellor and one game each with Rook+Ferz+Alfil+Tripper Queen and Archdeacons and Bishop+Wazir+Dababa+Threeleaper Queen and ancient Rooks and ASRU-FIDE-CdPS-SDTI 10×8 tournaments have players play mini-matches with games with a range-2 version of the Monarch which is called Chancellor inserted into the 9×8 lineup or one game each with Rook+Ferz+Alfil+Tripper Monarch and Bishop+Wazir+Dababa+Threeleaper and crowned Alibaba+Threeleaper+Tripper Chancellor and Bishop+Wazir+Dababa+Threeleaper Monarch and crowned Alibaba+Threeleaper+Tripper Chancellor and natural 10×8 tournaments, a format which the revived Accademie dei Lincei govern, Pontificale in cooperation with the CdPS and Nazionale in cooperation with the Federazione Scacchistica Italiana; FSI, the rare SCS-ACL 13×8 and ASRU-FIDE-CdPS-SDTI 12×8 [11 and 12 wide are by far the least rare of the larger formats since they can have heights that are at least square] tournaments, being these with the range-2 versions of the pieces inserted into the lineups, and the Vereiningter Germanistischer Schachbund, VGSB (whose primary members are the Deutscher Schachbund, DSB and Österreichischer Schachbund - ÖSB)-Goethe Institut Courier-Spiel tournaments have players play mini-matches with games with modern Queen, Crowned Rook and Centaur Prince or Rook+Ferz+Alfil[+Tripper] or Bishop+Wazir+Dababa[+Threeleaper] Queen, Crowned Dababa[+Threeleaper] Schleich and Centaur Princeling depending on the range of the Archdeacons, also run in abbreviated formats where the players only play games with the strongest lineup). In addition, the field must have an average rating of at least 2480 (abbreviated scale 2280) and must include at least three doctors, and must include players from a mix of national federations. Since December 8, 1965, CdPS players who have held the Doctor title for one year since they have been Bishops are eligible to be Cardinals of dioceses (of whom the Cardinals and Archdeacons of Barcelona run the modern CdPS and though there is no lower age limit on the CdPS offices, they are rarely formally granted to children). East Asian federations, in addition to using the 9×10 two player and 9×12 three player games commonly, borrow the dan system of the local chess games (China, Korea and Vietnam also have an alternate king with the telepotency rule and cannon moves for the linear jumping pieces for widths up to 37 and Japan also has the Shogi major pieces though the Free King is technically speaking a promoted crowned Alibaba[+Threeleaper+Tripper] for widths up to 35) for higher distinct titles, by which they also call foreign players, with each dan at the next higher 100, with extra credit for going through the usual norm requirements elevated by 150 per dan.
The Société des Tournois Interzonaux (SDTI, initially formed in 1954 as a foil to the perceived Soviet domination of FIDE’s World Championship cycle, primarily by extra-Soviet Communist players and headquartered in Berlin) also awards Junior Doctor titles to male players under 20, Junior GM titles being added in 1982 and Junior IM in 2006. Just like the real female titles, these titles are controversial, in part for requiring the player to be male to gain them, and no other federation grants them independently. As a result, most male SDTI players have only come under the organization since turning 20.
The title may also be awarded directly without going through the usual norm requirements in a few high-level tournaments, provided the player has a rating of at least 2400 (abbreviated scale 2200) classical.
These include:
Reaching the final 16 in the federation’s World Cup or the SDTI Interzonal
Winning the ASRU World Championship for the SCS, ACL, FIDE, CdPS or SDTI title
Winning the World Junior Championship (U20)
Winning the World Senior Championship, both in the 50+ and 65+ divisions (since 1965 also winning the 35+ division outright; any way but this is unheard of even with the lower rating requirements, especially instruments earning open titles from exclusively ASRU tournaments is as there are simply overwhelmingly more attractive opportunities for them to play against humans and Demi-instruments, these mostly being the children of men and female instruments I. E. their instruments’ wives, than there are for them to play against other instruments)
Scoring 95% or more over at least 13 games at an olympiad or other special events (since 1965)
Winning a Continental (e.g. Pan American, European, Asian or African) championship
Romantic (quasi) legends have that there was already a stably distinct Proto-Chaturanga for ancient Indian musical instruments. However, what the Royal United Chess Association/Academy (Associazione/Accademia Scacchistica Reale Unita, ASRU) within the United Federations/Universal Federation of the Greater Game (Federazioni Unite/Federazione Universale Giocata Maggiore, F[F]U[U]GM), as well as its open counterparts FIDE (in Spain, the Institut d’Estudis Catalans [IEC] runs the game in cooperation with the Federación Española del Ajedrez [FEDA] and is the primary custodian of the 8×8 game with the modern Queen, the 8-wide formats being the primary formats governed by the open organizations) and the Congregatio de Propagandis Scachis, CdPS (primary governors of chess due to the involvement of the Valencian abbot Bernat de Fenollar in the foundation of the modern Queen and a major and one of the two least controversial divisions of the overarching Congregatio de Propagandis Operibus, CdPO, fully enshrined by the First Vatican Council, along with the Congregatio de Propagando Ludo Dominarum, CdPLD), has induced is the third most recent of the distinguishing ideas within its modern game are due to the Calabrian Priest Pietro Carrera’s Il Gioco degli Scachi of 1617. These ideas are:
1. The strongest of the “Centaur” pieces that can appear in the opening, the Centaur King, being the Centaur from this book while the Centaur Prince and Duke are a crowned bishop and knight, which have been known since Arabian [decimal] Shatranj (the Centaur Duke has technically been known for all of chess history, but its existence along with that of the Archdeacon and Centaur Princeling [since the English Revolution of the 17th century, where it became common for the humans to play chess with each other like this, and the subsequent and corresponding Clarinet-Pianoforte Revolution of the 18th century where these pieces came to primarily have range 3, and as a result of this and the aforementioned existence of the Catholic Church’s board game organization, which fully started during the conversion of “northwestern” churches outside of primarily France, Italy and the Iberian Peninsula to liturgical languages one step less removed from the vernacular due to the early successes of printing in the 15th century, there are cutting-edge chess books published originally in German and Italian, and chess masters commonly have an instrument that is someone fluent in either language] has only been a fixture of the rules since Arabian Shatranj came to be played only with piece crowning in emulation of Al-Qirkat and re-entry in emulation of Tables)
2. The board of 8 files of 10 squares with the Centaurs set up Dukes b0/g0/b9/g9 and (Kings and) Princes d0/(e0)/d9/(e9) though it is secondary to the even larger formats on 11×8 (pre-existing, main format for two-player standard time controls of multiple minutes per move/up to 30 moves per hour at titled levels and considered odds-lite as Centaur Kings and Emperors don’t exist and other crowned pieces are rare and doesn’t always use the medieval piece proper and conversely the Society for Classical Studies and American Classical League run this game without the modern Queen), 8x12 (since the subsequent invention of Three-handed Chess by Capt. Phillip Marinelli in 1722, wherein the rule of capturing twice to eliminate the pieces eventually develops, the 12-high formats are primarily three-player games, for which this is the main format)/12x8, decimal, 13×8, 11×10, 15×8/10x12/12x10, 13×10, 11×12, 12x12, 15×10, 13×12, 15×12 and even 17×8, 17×10 and 17×12 boards where the odd width boards use pieces with both the ancient (Ferz+alifi) and modern bishop with doubles of the Centaur Princes, and since the publication of Johannes Kohtz’s hypothesis, at least due to knowledge of the Arabic master al-Adli’s writing on chess in ninth-century India (c. 840), of an ancient Rook move of 1 or 2 squares orthogonally without possibility of obstruction in 1903 (Das Indische Problem), the subject of Kohtz’s real significance in the European history of the idea being currently still unsettled, though he is most likely to have acquired it through his kinship with Ströbeck and the crowned Dababa in Courier-Spiel as a German, even larger boards up to 29×8, 29×10, and 29×12
