Soyez attentif !\n\nLe but est d'avoir un tournoi rapide qui ne puisse pas s'éterniser en attendant un ou deux joueurs plus lents. Une horloge canadienne est utilisée, qui ne se comporte pas comme l'horloge Fischer le plus couramment utilisée. Pas de pause le week-end.\n\nLe handicap est activé pour augmenter l'intérêt des parties.\n\nSi les outils me le permettent (c'est le premier tournoi que j'organise), la nouvelle ronde sera démarré dès que tous les joueurs n'ayant ni abandonné ni été disqualifiés auront terminés tous leurs matchs.\n\nBon jeu !\n\nWarning ! This tournament has several specific settings. Read carefully !\n\nThe idea is to have a truly fast tournament that is not dragged down by one or two slower players. A canadian clock is being used, that behaves differently from the usual Fischer clock. The clock keeps ticking on week-ends.\n\nHandicap is on in order to make all games challenging.\n\nIf the site tools allow it (It is the first tournament I manage), new rounds will be started as soon as all games by players that did not abandon nor were disqualifid are over.\n\nEnjoy !",
