"only XL-5"

There is a reason. The round time has ended. The pair did not play. These are two players, one of whom remains active in the tournament thread and in the dialogue with the judge.
The other is not, and this is a fact known to the judge.

As for the opponent, he didn't write to me - neither in ICQ nor in a private message...

The second player is out because he essentially ignored the tournament and the judge. L - Logic.
