  Solution :
  La pièce à ajouter en d1 ne peut être une Dame : comment le Roi aurait-il passé par dessus? -
  ni un Fou : les Fous ont été pris au gîte - ni un Cavalier : tous deux sont encore vivants
  et aucun n'a pu être créé - de surcroît, ni la Tour h1 qui ne permettrait pas la solution.
  Reste donc la Tour a1 dont la présence en d1 n'est possible qu'après le roque et il faut que
  le roque ait eu lieu à ce dernier coup qu'il s'agit de reprendre pour qu'en rétablissant
  la Tour en a1, le problème soit résolu par 1.a4#.

  Add Rd1, then take back O-O-O and forward 1.a4#"
