1..f4!+ 2Kxf4 Kd4 3 a5 e3 4 a6 e2 5 a7 e1Q 6 a8Q Qe5+ 7 Kf3 9 Qe3 mate.
and if 3 Kg3 e3 4 a5 Kd3
Of course after 1..f4 2 Kd2 h4! and then black moves his king to the a pawn.
By blocking with 1..f4 2 Kd2 h4 the kingside the white king cant stop the losing of the a pawn.
Couldn't decide which version you liked best?
Black moves first. After 1... g5! White can`t avoid the mate.
2 f7 Rh4+ 3 Bxh4 g4 Mate.
but do you realize that this is actually the hard part of the puzzle and the part that is of interest???
