Game #13
Open Division Final
San Mateo, California
September 21, 1997
11 Point MatchCarmi Brandis (Blue) vs. Paul Tanenbaum (White)
Score: 5 - 8Analysis by Ron Karr
An all-star line-up is on hand for September's featured match. Carmi Brandis and Paul Tanenbaum are charter BACKGAMMON BY THE BAY members, and each has participated in every 1997 BGBB tourney. They concretely disprove the adage that nice guys finish last (well actually, in backgammon it's good to finish last, but you know what I mean). Ron Karr takes a brilliant turn in the game analyst's seat, particularly in his ability to put into words the lessons JellyFish has to impart.
