Using only half of a chess board you may place five queens anywhere. After you place them, I move each queen at most once with standard queen moves. If I make a horizontal five-in-a-row, I win. Can you beat me?
(In reply to re: What about...+ most of a solution
But shouldn't the "five in a row" be next to each other?
At least that's how the "four in a row" game is played.
