In Response To: Another puzzle/ next question/ SPOILER I hope)_ (Nack Ballard)

"I agree that the maximum number of Xs that can be played onto a grid is N(N-1), and that is always an even number. But it seems like a big leap from there to conclude that with best play player B (the second player) always wins. "

Agree it is a leap. Thought I had it but as you show not yet. My strategy doesn't work. Still my conjecture though that 2nd player can force a win.
