“Spring 2013” season. Online ranked games (reports, confirmations, discussions).

3. I contacted the AK not to ask them to award me the victory, but to clarify whether I also have the right to throw opponents in a similar way.
Don't believe me, ask Pit for LM.

Personally, I believe that each player has the right to save the game at any time. After all, we don't play for 90 minutes, like in football, but sometimes for 9+ hours. Urgent matters, etc., can always arise.
The problem of unfinished games does exist. In casual games, many, realizing that the situation is not very good, prefer to start a new game.

Well, ideally, it would still be correct to discuss before the game how much time each player has for the game. If the game is not a tournament, but just a casual game, then it is highly desirable to clarify whether the game is being played for a record. And seasonal games should preferably be played with a person with whom it is comfortable to play and there are no problems with agreements.
