The shortest way to a day of rest for the chess pieces is a sharp combination - Bronstein
The combinations are to be solved by writing moves in the given input boxes. Moves need to be written in Algebraic Notation. Please do not use +,#. In case of piece moving from one square to another - example Rook is on 'g1' , and you want to move it to 'g8', write Rg8. A hint in terms of ply (total moves required - white + black) will be given.
