=Draw by Reputation=
In round five, the mighty [[Mephisto Lyon|Mephisto]] by [[Richard Lang]] played [[Échec|Échec 1.9]] by [[Marc-François Baudot]] and [[Jean-Christophe Weill]], and around move 23 the Mephisto team were clearly getting desperate and beginning to envisage the horrifying prospect of losing a lot of prestige - and maybe even the world champion title. Just a few moves later, with Mephisto the exchange down and showing an evaluation of -2, Échec began to repeat moves, and a [[Repetitions|draw by repetition]] was fixed on move 32. The explanation was the amateurs had set their [[Contempt Factor|contempt factor]] to no less than four Pawns. As [[Michael Valvo|Mike Valvo]] remarked in the bulletin: this particular draw by repetition might better be labeled a draw by reputation <ref>[[Thomas Mally]] ('''1990''').

=Draw by Reputation=
In round five, the mighty [[Mephisto Lyon|Mephisto]] by [[Richard Lang]] played [[Échec|Échec 1.9]] by [[Marc-François Baudot]] and [[Jean-Christophe Weill]], and around move 23 the Mephisto team were clearly getting desperate and beginning to envisage the horrifying prospect of losing a lot of prestige - and maybe even the world champion title. Just a few moves later, with Mephisto the exchange down and showing an evaluation of -2, Échec began to repeat moves, and a [[Repetitions|draw by repetition]] was fixed on move 32. The explanation was the amateurs had set their [[Contempt Factor|contempt factor]] to no less than four Pawns. As [[Michael Valvo|Mike Valvo]] remarked in the bulletin: this particular draw by repetition might better be labeled a draw by reputation <ref>[[Thomas Mally]] ('''1990''').
