Shoot Pool, not people
Good analysis here, so I don't need to repeat it. Jean dominated small fields of players with no one really close to her speed. The only time she got pushed was playing against the men and she held her own there. I used to say that given time and experience Jean might win one of the big Men's tournament. That didn't happen because she retired at the ripe old age of 29 to run her family's poolroom and make a good living for herself (smart lady).I was fortunate to have seen both Jean and Allison in their primes.
Jean never had to face the really stiff competition that Allison faced.
Yes, there were a few female players who occasionally gave Jean some tough matches...Robin, Loree Jon, Ewa, Belinda, etc.
But she completely dominated the field in most tournaments during the 1970's and 1980's.
After Jean withdrew from competition, Allison rose to stardom during the 1990's and the 2000's in the US.
Allison faced tougher competition than did Jean during her career...Jeanette, Karen, Kelly, Gerda, etc.
But, if I had to make a wager, I'd go with Jean.
No question Allison faced much stiffer opposition and still found ways to win. She got pushed hard by first Karen Corr and next Kelly Fisher, and yet Allision persevered and continued her winning ways. She is rightfully the all time greatest women player, even though the new breed of Chinese women may be even more skillful than she was. Let's see if any of them have her longevity and winning record. Siming Chen is her heir apparent in that respect.
Who would have won a match between Jean and Allison? My opinion is it would be close, with it going either way. Jean had a bigger upside with her powerful game and Straight Pool knowledge, but Allison was the most determined player I ever saw. She knew how to win and never gave an inch. Reminds me of Buddy Hall there. Both of them would beat you 11-0 if they could and then smile and shake your hand.
I was fortunate that I got to know both these ladies on a personal level. Two high class individuals is all I have to say! Humble, kind and not self absorbed in any way. Two real beauties in my book, and champions to boot!
