Hello Bill and everyone,
Check http://web.cs.ualberta.ca/~javhar/hex/hex-yproof.html for a
simple proof using the game of Y. The proof has been around for over
thirty years but did not come to light until I discovered a closely
related proof (which was published in Issue 12 of Abstract Games.)
Regards,
Steve
