You notice there are several chess variants here. Many of them (such as Atomic Chess, Dark Chess, etc) are completely different from regular chess. But there hasn't been any chess players complaining abou them - if they don't like the game, they don't play the game. It could be the same here - if these games are created, you don't have to play them! But you shouldn't stop others from enjoying it because you don't appreciate it!
(Cacher) Si vous voulez jouer une partie contre un adversaire d'un niveau équivalent au votre, vous pouvez définir un BKR compris dans un intervalle lors de la création d'une nouvelle partie. Dès lors, personne ayant un BKR en dehors de cet intervalle ne pourra y accéder. (Katechka) (Montrer toutes les astuces)
