Chess Puzzle Solution
The game wants you to use a single chess piece to put the opposing King into check, while not putting your piece anywhere that the opposing pieces could takes yours.
The problem is a language translation. You don’t need to “checkmate” the king. Just put him into check, in a position where the piece cannot be taken. The solution will always be outside the 8 squares adjacent to the king.
The rook moves sideways and the bishop moves diagonal. The knight moves up 2 then over 1… basically every square 2 spaces away except straight or diagonal.
Try using the knight next to the bishop, on the edge of the board.
OR the rook in a square as far from the king as you can without it being taken.
