One for all and all for one - 2

Dirty_Player, I understand that this isn't done in professional chess. I just gave an example from life, from my childhood in a chess club, which is quite understandable if you try to understand. We used to shade the cells on paper with a pencil to make it visually clear. This might be a matter of taste, but I don't see anything wrong with it. Besides, you're talking about tournaments where there weren't double-round systems, but only single-round games, and this is what determines the choice of this particular type of table. The table I provided is an example to show that the cells that are duplicated in a single-round tournament are not duplicated in a double-round tournament, but each one has its own status. We will have 2 games, and each cell represents a separate game.
