White win with ♘a8:
1.-♘a8 , … c8= ♘
2.-♘b6 .. ?
And White wins with the move ♖b7 ++ inevitably.
A variant would be:
1.-♘ a8, …♖b4
2.-♘b6 .. ?
And White wins with the move ♖b7++ inevitably.
Another variant would be:
1.- ♘a8, …♖g8
2.-♘b6 .. ?
And White wins with the move ♖b7++ inevitably.
I answered above ...
1.- ♘a8, …♖g8
2.-♘b6, …♖g7
3.- ♖f8+,… ♚c7 (forced)
4.- ♖c8 ++
1-0
Women? :)
