But castling is illegal! This is because Black's dark squared bishop is a promoted piece and White's king must have moved to let the promotion through.

Henrik Juel: Removing wPh2 might help (2020-09-21)
James Malcom: The illegality of the castling is intentional. (2020-09-21)
A.Buchanan: I guess it is intended as a joke. There are numerous cooks e.g. R: 1. Dh1xDh5 Td6-b6 dann 1. Sb2-d2+! (2020-09-22)
James Malcom: Andrew, the White king is in check from the Black bishop. Ep is the only legal way to resolve it. Your suggestion is illegal. Did you forget to eat breakfast again? :) (2020-09-23)
A.Buchanan: Ha this is just like when I play chess otb - so hard to spot extraordinarily distant black pieces on dark squares :-) (2020-09-23)
James Malcom: Sounds fair enough to me! And the position is legal, not illegal, Andrew. (2020-09-23)
A.Buchanan: I meant "no solution" - and I've classified it as a joke which I think is the composer's intent (2020-09-24)
James Malcom: Quite simply, I agree. (2020-09-24)
Mario Richter: I think the "normal usage" of the keyword "no solution" in the PDB so far is to indicate, that the intended solution fails e.g. because of some hidden defense (which corresponds to the german "unlösbar").
This problem doen't fall into that category! In fact, it has as solution, namely that there is no mate in 3 after the (forced) retractions!
(There are 1064 cooked problems with the keyword "no solution", only 9 "no solution" problems with the label "C+", and for all of the latter either the "no solution" or the "C+" is wrongly attributed.
Perhaps the simplest way to handle the Pedrag-problem is to add "intended" to the KW "no solution". (2020-09-25)
James Malcom: I agree, Mario. It is now doe. (2020-09-25)
A.Buchanan: Yes that's fair. Most jokes follow a template, but this is quite original. (2020-09-25)
