is a manner of defining.

both chess games I have lost were won beyond doubts.

nice quiz btw what happened there ... :D

I don't know anyway which game-type was targeted in particular
but I hardly could imagine it as an acceptable treating ...

an umpire would be required with highest possible own skills, for each type,
and would not be that player also a competitor for the players he has to judge ?
