Experiencia de torneo en OGS

Si hace unos días decía que me he reconciliado con el servidor OGS, hoy vengo a hablar de uno de los componentes que señalaba interesante: los torneos.

Tienen dos tipos de torneo, por correspondencia y en vivo. Hace como una semana intenté participar en uno en vivo que no se acabó de celebrar, no sé si fue porque éramos pocos los que nos intentamos apuntar o por qué motivo. Aquel iba a ser en un tablero de 19x19, hoy he participado en uno de 9x9 en vivo que si se ha llegado a llevar a cabo. Aunque cabe preguntarse si he "participado" como tal porque de 5 rondas, he perdido la 1º por llegar tarde para jugarla porque pensaba que empezaría más tarde (por 5 minutos no jugué la primera partida, que siniestro). Si hubiese jugado la primera y hubiera ganado, podía haber quedado 3º ó 2º porque he quedado 4º perdiendo esa partida por tiempo y la última.

La verdad que el sistema de avisarte y que comience esté bien, pero lo de jugar torneos en vivo me parece muy complicado por eso de la hora a pesar de que algunos sitios te pongan a que hora empieza y te ofrecen un link para saber a qué hora sucederá eso desde el sitio que te conectas (mi fallo de hoy es que ese sitio me daba la hora del torneo pasado que no se hizo y no sé porque no sé porque en esa página me daba la misma hora...). Luego me he apuntado a varios torneos por correspondencia, la verdad que están más o menos bien si lees todos los datos y tienes en cabeza las normas y como van a ser esos juegos, tanto en tiempo como en handicap.

Uno de esos torneos en los que me he metido por correspondencia ha empezado y es de los que incluye handicap. Serán 10 rondas, para cuando quiera acabar ese torneo lo mismo estoy ya jubilado ya que se puede hacer una jugada cada 3 días (y tiene las reglas que por cada jugada se te suma un día más hasta un máximo de una semana... vamos, que si alguien juega sólo 5 jugadas a la semana, hace que acabe llegue el juicio final antes de que acabe la ronda). Tiene 8 grupos que son de 4, excepto uno de 3, vamos, que somos 31 jugadores si no deja ni entra ninguno nuevo (porque pueden entrar jugadores provisionales). Ese torneo es de estilo "Simultaneous McMahon" (más adelante explico en que consiste ese y otros tipos de torneo que hay en OGS).

Y bueno, que estilos más de torneos hay y en qué consisten, creo que en sí no puedo resolver esa duda que citando literalmente la información que da OGS:

Introduction to Tournaments

OGS tournaments provide you with a way to compete against a variety of opponents. They are usually a mix of real-time and correspondence style tournaments created for players of various skill levels.
Site-wide tournaments are organized and run by OGS Administrators but Groups are allowed to run their own tournaments for their members.
All tournament games on OGS are ranked games. Provisional players are allowed into most tournaments, however results from provisional games will not effect the rating of non-provisional opponents. Generally speaking, playing in tournaments is a great way to establish your real rating and remove your provisional status.
Note that because games are ranked there may be consequences for individuals who misrepresent their skill level, including disqualification.

Group Tournaments

Group Administrators have the option to create and run tournaments for members of their groups. The same tools that are used to create and run site tournaments are provided, including configuring:

• Rank levels
• Tournament type
• Rules
• Handicap settings
• Time controls

Group Administrators who start a tournaments become the Tournament Director for that tournament. A Tournament Director has several management abilities, including:

• Disqualify players
• Decide the outcome of a tournament game in a certain player's favor (or as a draw)
• Add or deduct tournament points from players during a running tournament

If you are acting as the Tournament Director for your group's tournament it is important to be a fair and impartial arbiter of those games for the enjoyment of all participants.

Tournament Types

OGS supports the following tournament types (with more planned to be added):

Simultaneous Round Robin

minimum tournament size: 2, maximum tournament size: 10

This tournament type supports a maximum of 10 players. Each player is paired with every other player in a single round and all games are played at the same time. The winner is decided by most wins using the Sum of Defeated Opponent's Scores (SODOS) as the tie-breaker in the event of a tie.

Swiss

minimum tournament size: 4

All players start the tournament with 0 points and are awarded 1 points for wins (0.5 points for a draw). The method of pairing players is similar to the Traditional McMahon system (see Pairing Methods for details). Tournaments run for: (P + 7 x Q) / 5 rounds. Where P is the number of players and Q is the number of qualified places.

Traditional McMahon

minimum tournament size: 4

This tournament type is somewhat similar to Swiss with some notable exceptions:

• The number of rounds is decided up front
• An upper and lower bar is defined when the tournament is created. Anyone above the upper bar starts with 0 points. Anyone below the upper bar but above the lower bar starts with a negative score representing their number of ranks below the upper bar. Anyone below the lower bar has the same base score. Lets look at an example:

Lets say we have a tournament where the upper bar is set at 3k and the lower bar is set at 6k. Here's how it would look:

Player	Rank	Points
user1	1k	0
user2	2k	0
user3	3k	0
user4	4k	-1
user5	5k	-2
user6	6k	-3
user7	7k	-3
user10	10k	-3

We cover our pairing algorithm for McMahon later (see Pairing Methods for details). Ties are broken first by SOS (Sum of Opponent Scores) and, failing that, SODOS (Sum of Defeated Opponent Scores).

Simultaneous McMahon

minimum tournament size: 10

This tournament type is very similar to the Traditional McMahon tournament except that at the beginning of the tournament the field is divided into evenly sized groups of no more than 7 players. Each player will play simultaneously against all other group members. At the end of each round the groups are regenerated. Groups are generated based on the number of tournament points.
