The Local Backgammon Tournament

Every Wednesday at 5pm at the El Torito restaurant in Burbank, California Gammon Associates Patrick Gibson runs a local backgammon tournament. The range in skill level among the players there is vast as it is held in the social setting of the restaurant where a few casual players who have little or no experience attend. Much more common are the experienced players whose skill levels range from intermediate to world class.

Last Wednesday I was fortunate enough to win five consecutive rounds and win the tournament. Today we'll look at a dozen positions that came up from these five matches to see if I was a worthy champion, or just got lucky.

In our first position (Local 1) from the first round, I had a five and four to play. I was way down in the race and had to decide whether to hit loose and make my ace-point (8-3*, 5-1), or play safe (6-1, 5-1).

If I chose to hit loose and make my ace-point, I would be giving my opponent 15 numbers to hit me back with and since they held a five-point board and owned the cube, if I was hit back it was going to be very detrimental for me.
