You have a square 5 x 5 board with four rooks in the corners:
|
Note: for reference, assume the rooks are labeled A, B, C, D as follows:
A B
C D
|
You can move the rooks horizontally or vertically. The only problem is that when you move a rook, it will keep going in the same direction until it hits another rook or the edge of the board.
You want to move a rook into the darkened square on the board.
How can this be done in no more than 10 moves?

the Sliding Rooks in 4 moves by kirk smith)
But the problem states that a rook keeps moving until it hits another rook or the edge of the board. Your fourth move would not stop on the center, but actually keep moving and finish at cell C1.
