Rg5-b5, and after every uncapture (uncapturing nothing isn't allowed, due to retrostalemate), white has 1. Rg8# d) -1. Rh5-b5, and after uncapturing a queen or a rook, white has 1. Ng5# (duals after the other 3 legal black decisions) e) -1. d7-d8=R, and white has 1. Rh5# (-1.e7xd8=R fails because black decides white uncaptured a knight)
