Mary, Mary!
This article deserves a 10! Awesome, truly. I agree with Phil in that I believe the foundation for building success in one's own game is a realistic, objective assessment of one's own weaknesses. Adopting strategies and tactics that subsequently avoid your own "misgivings" is at least then possible. Otherwise there is nothing to add, because you covered every detail!
Even to the extent of finding a perfect third person pronoun, of English derivation, to describe the average backgammon player, (of either sex). That this term was originally developed by the great backgammon theoretician Oscar Mayer is merely coincidental.
Excellent article!
