I’m new here (and new to Go) and still in the learning process, though I love it!
Recently I had a lot of game cancellations from opponents. I realize that games cancelled are not taken into account in the score (or level) of a player, even though it seems to me that when you bail, you lose… (?). Is there a reason for that? Can a player cancel anytime he wants, even near the end of a game and then espace from losing the game?
Game creators are allowed to cancel for any reason. This is because they do not have an opportunity to vet the opponent. In contrast, players who accept a challenge are expected to play, because they can, if they wish, vet the opponent beforehand. Acceptance of a challenge followed by cancellation is a reportable offense.
