The Sliding Rooks (Posted on 2004-03-08)

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?
