I was in a tournament the other day and doing very poorly, my only win due to a bye. I was paired up in my final round, and the prize structure was such that my opponent would likely get a prize if he won, whereas I would definitely not be getting one. In any event, I decided to stick it out because I was still having fun and I was there to play Magic — even if there was no chance for me to win prizes.

I won the first round; my opponent won the second round after time was called, leaving the match results tied. I decided to give my opponent a chance to win prizes, so I conceded to him at this point. This got me curious about how exactly the concession rules work. Per the Magic: The Gathering Tournament Rules:

If a game or match is not completed, players may concede or mutually agree to a draw in that game or match. A match is considered complete once the result slip is filled out or, if match slips are not being used, a player leaves the table after game play is finished. Until that point, either player may concede to or draw with the other, though if the conceding player won a game in the match, the match must be reported as 2-1. Intentional draws where no games were played are always reported as 0-0-3.

Why the 2-1 and 0-0-3 reporting?

Additionally, this implies the following odd scenarios:

1. If we had a drawn game or two somewhere in there (let's say the final result was 2-1-2 in my favor, and then I conceded), it looks like the match must be reported as 2-1 in my opponent's favor (without the draws being reported). Is this intentional? Why not have it be reported as 2-1-2 in my opponent's favor?
2. What is an intentional draw reported as when games were played? Using the same example, if the final result was 2-1-2, and then we decided to draw so we could both make top 8, how would it be reported? Per the rules, the "0-0-3" reporting is for "intentional draws where no games were played", which is not what this was. Would it be 1-1-2?
