I think the real issue is to alert the players to the fact that a drawn
game has in fact been achieved so the game can be concluded and the final
round started.
It is evident that both players were suffering from the same misperception
of the PMC draw rules. Carlos had earlier posted an inquiry to the PM page
about a perpetual check draw. I answered him that the rule was the same as
in FIDE--perpetual check is not a draw per se, but always leads to triple
repetion or the fifty-move rule (virtaully always the former).
It is self evident that Carlos intended to achieve a draw--Antoine has a
won game absent the perpetual check--therefor he must have been unaware
that he has done so.
