    What if Black plays Rh8 in the first move?

    There is not mate in 5. Minimum mate in 6.

     



    1. Rh1 Rh8 2. Nf4 h4 3. Rg5!  If 3...Nxg5 then 4. Rxh4#.  If 3...Kh7 then 4. Rh5+ Kg8 5. Rxh8#.

    I continue to believe that any "mate in n" that doesn't include sequential checks with no alternatives is really not valid. There are "outs" for black here that prevent the "mate in 5."

    It is only "mate in 5" if black CHOOSES (voluntarily) to play a certain set of moves. That can hardly be considered a guarantee.

    You couldn't be more wrong.  Even with the first two moves of the solution not being checks, black has no moves which prevent mate in five.

    Lots of lines to consider. Here are a few that I don't think have been mentioned, including 1...Rh8 and some that have been covered by other posters.

     

     



    Got it , and another important variant :
    after 2 Bxh4 ... Nxh4 ? 3. Rg4 then the black has no move against 4. R1xh4#

    Thanks BenTal !
