Happy 4th of July!!!

On Tuesday, 6 July 2004, the Backgammon Club of San Diego met. Patriotically, we held a tournament.


Tournament News

9 people entered a 16-player bracket and a four-player blitz tournament on Tuesday night. We had the following tournament results:

Main Tournament (16 player bracket)
  • 1st place:  Sho Sengoku
    
  • 2nd place:  Jason Lee
    
  • 3rd place:  Fred Kamgar / Bruce Haight (split)
    
  • Blitz Tournament (4 player bracket)
  • Winner:     Tom Fahland
    
  • For the second straight week, we failed to reach double digits in attendance -- the first such time since March. We did, however, manage to run a blitz.

    This problem actually isn't all that fancy. It's just a question of making the best of a bad situation. 6/4* is right because Black has to do SOMETHING to stop White, and 13/10 is then right to give a checker to cover. Lifting the blot just lets Black's situation go from bad to worse. The path to victory is the sequence following this play of dance, cover. Then life isn't so bad for Black! That's optimism for you.

    Virtually any other play allows White to fire a cube over -- this play can at least stave that off for a while.
