Pretty obvious, since white king has moved (the rook at d4 must have come from h1) so 1.Rad1!
If 1. Rad1? then Black castles.

ilywrin, have you heard about under-promotion. 🙂 pawns can be promoted not only queens, but to rooks, knights and bishops too.
Originally posted by ilywrinOK, I am getting too old for this. What is wrong with the following premises (as a possibibility):
See the bishop at b8 it must have gooten there through h6 so g6 was played before 🙂
Originally posted by Mephisto2See my previous posts, I have totally agreed with that but THUDandBLUNDER insists that there's a solution.
OK, I am getting too old for this. What is wrong with the following premises (as a possibibility):
- the last two moves were a7 by white and g6 by black
- black can castle, meaning that
--- the bishop on f8 was captured before by a white knight
--- the bishop on b8 is a promoted one, a pawn promoting on g1 (black's d-pawn, after capturing two other pi ...[text shortened]... t the black pawn came to f2)
That would mean no solution, since Rd1 would be followed by 0-0.

My only reasoning in this case is that since the condition of the problem cannot be met if Black can castle he shouldn't be able to, in order to have a solution 🙂
Originally posted by THUDandBLUNDERisn't it sufficient that there is no proof that black lost his castling right? Apart from a flaw in my set of premises (which I hope you will show us if that is the case), then I think we cannot exclude black castling and hence, escape from mate in 3.
Can you prove that White can't castle?
Can you prove that Black can't castle?
Can you prove that not both can castle?
