Sune, I feel that your sample argument neglects the role of a responsible FIDE
arbiter in a world championship match. Someone must see progress even if it is
not involving the exchange of pieces of advancement of pawns. If progress can
not be shown-- and tablebases will help here-- a draw claim ought to be upheald.
It is in fact a sad state when an arbiter is unfamiliar with complex endgames
yet must deal with claims of competing grandmasters under current time controls.
this has happened in the usa quite a bit. I have heard stories-- but I will not
repeat them and name individuals.
