Here's a "simple" task for all of you solvers out there: With White to play first, and with both sides working together to checkmate White, aka a helpmate, what is the quickest way for Black to checkmate White?



All normal rules of chess apply. The Black pawn on Black's first rank moves and promotes like a normal Black pawn. However, it is not allowed to have a double-step on it's first move. It moves down the board.



enter image description here



UPDATE: Just for fun, here is a slight variation of my main puzzle that should definitely take longer to complete. How many moves can you complete it in?

          My basic goal was to move a white bishop next to the black pawn so that the black pawn could start moving down the board. But to do that, one of the white rooks had to be removed in order for the white king to get out of the way. I'm pretty sure someone can find a more optimal solution.

            For starters,




            the first moves must be 1. Bc7+ Kxc7; otherwise the Black king has no moves and it's stalemate.

              @greenturtle3141 first moves are incredibly important; it can change the whole game in the biggest of ways. So I'll have to disagree with you there, but most partial answers aren't very great when they are one line long ;)

                My basic goal was to move a white bishop next to the black pawn so that the black pawn could start moving down the board. But to do that, one of the white rooks had to be removed in order for the white king to get out of the way. I'm pretty sure someone can find a more optimal solution.

                    For starters,




                    the first moves must be 1. Bc7+ Kxc7; otherwise the Black king has no moves and it's stalemate.

                      @greenturtle3141 first moves are incredibly important; it can change the whole game in the biggest of ways. So I'll have to disagree with you there, but most partial answers aren't very great when they are one line long ;)
