"description": "Este torneo es completamente libre, sin importar niveles ni habilidad. La idea es jugar y divertirse, y especialmente, conocer y poder charlar con los uruguayos que, ya sea porque viven lejos o por falta de tiempo, no pueden juntarse a jugar en persona con nosotros los jueves.\n\nLa fecha de comienzo es el 15 de febrero, para después de Carnaval. La idea es que cada ronda dure menos de dos semanas por partida. \n\nSe ofrece la modalidad de correspondencia, pero la idea es que no se extiendan demasiado.\n\nSe solicita colaboración para esto, que los contrincantes conversen entre ellos y coordinen una fecha y una hora que les quede bien para jugar la partida, dentro de las dos semanas. También se puede intentar terminarla en dos semanas jugando por correspondencia normal, pero esto requiere que los dos jugadores estén haciendo varias jugadas por día todos los días y corre el riesgo de que no alcance el tiempo. \n\nAsí que, como se ve, no es un torneo formal, tiene flexibilidad horaria, y la idea es conocerse, jugar, aprender y divertirse. Son todos bienvenidos, anímense!\n\n\nNota: Las partidas de la primera ronda deben estar terminadas para el 1ro de marzo. Si para entonces alguna pareja aún no terminó, se le concederá la victoria al jugador que quede con más tiempo disponible en la partida.",
