Norm and Ray were about to sit down to a game of chess when Sally walked in.
"Still playing the same boring game?" she asked, "Let me make it more interesting. I'll set up the pieces on the board a little differently."
"OK," they said, glad to let someone else take care of the chore of setting up the pieces. When they sat down to play, it seemed that only a few pieces were in an unusual position.
"Come on, make your move," said Norm. But when Ray picked up a piece to move, Sally said, "No, that would be illegal."
Ray's brows furrowed for a minute, and then he saw that she was right. He pondered the board for a few more minutes.
"I can't move," he said, "and what's more, neither can you."
How had Sally set up the board?
Can you think of another such setup of pieces, that is substantially different from this one, and in which neither player can move or capture?
I give up, show me the solution.
