Although the question is different, the underlying theme is the same: Is
castling allowed if it can be proven that, by castling (or in your case:
by making it possible to castle), more than 100 single moves without
capture, pawn move or castling have occurred?
Your example could be changed to something even more extreme by the way:
Ke1 Rh1 Sa1 // Ke8 Ph2
No captures/pawn moves for 46 full moves. How many times can the
sequence Sb3 Ke7 Sa1 Ke8 be repeated until there is a correct claim for
