Weiß kann Selbstmatt ohne einen eigenen Zug erzwingen.
Schwarz rochierte im letzten Zug, obwohl er im Schachstand und ignorierte dabei auch das Schach auf d8. Beides ist illegal. Er muss diesen Zug zurücknehmen und statt dessen Df7# oder Txg6# spielen.
A.Buchanan: No retro analysis to show that last move was in fact castling. Position is not illegal. (2019-10-21)
James Malcom: Perhaps that's why it labeled as a joke then. Andrew. (2020-10-20)
A.Buchanan: Yes it’s a joke but there is an existing species of problem where the position Is illegal. This is kind of like Conan Doyle vs Agatha Christie: here we are only told the key clue after the fact. I am sadly interested in classifying the main families of jokes, identifying which ones are fairies as well etc. This one is not fairy I think. In constraint promotion into foreign units can be joke depending on stipulation, but is definitely fairy (2020-10-21)
