When Keith was in his prime, and putting the smack down on everyone, who was his biggest arch-rival? What I mean is, who was the person that gave Keith the biggest run for his money playing 9ball? It could be in a tournament setting or playing for money. All players had one particular opponent that gave them alot of trouble, i.e. Efren had the most trouble with Sigel, Archer had the most trouble with Bustamante, and Earl has admitted Efren was his biggest rival. Just curious who Keith would pick as his arch nemesis.
