Paul Magriel, aka X-22, passed away in Las Vegas on Monday, March 5th 2018.
X will always be remembered as one of the greatest legends of the game, the godfather of modern backgammon and author of the backgammon bible called "Backgammon". His unforgotten achievements in backgammon and poker are plenty and many.
A great loss for backgammon. Rest In Peace, Paul!
