     Partie nulle par application de la règle des 50 coups. Mais... La règle des cinquante coups ne s'applique pas d'après le codex de la composition échiquéenne chapitre IV, conventions diverses, article 17 codex.htm, sauf dans le cadre de l'analyse rétrograde. En revanche, la règle de la nulle en cas de troisième répétition de la même position s'applique à tous les types de problèmes (article 18).
