Nack wrote, "43S-65R-55 (diagrammed below): Your XG 5k RO has E (10pt + 1pt) beating P (5pt) by only .018, and A (3pt + 1pt) by .063. Your old 324-trial Snowie-3 trunc had E beating P and A by .050 and .083, respectively. That trunc with big margins seems to have been your sole data reference when you wrote your fine 1994 article, The Naked Ace Point), later mentioned in my intro to Backgammon Openings, and we never bothered to get higher quality data (until now)."

Actually, my article appeared before either Snowie or Jellyfish had been released. Believe it or not, I used to do manual rollouts of positions, maybe 108 times. My article was based on a manual rollout. Took a long time and the variance was high, but I learned a lot about what variations can occur, and different ways games can be won or lost.
