Names with accented or non-English letters have been converted to an English representation with a 26-letter alphabet. Many people use erratic capitalization, so I determine proper case by algorithm; if this does not correctly display your name, please advise and I will add it to the exception list. If you wish to contact someone whose name you see listed (such as a lost friend) give me permission to send your address to that person, then he or she can contact you. I will not give out e-mail addresses (these are private and go nowhere from me).

Location Ranking

This table lists all the participating locations, ranked by the average score of their entries. The “Best” column shows the best finish (by rank) of any player in that location. Locations with less than five entries are ineligible for the top ranking and grouped separately.

Bot’s Eye View

I posed these play problems to some of the well-known bridge computer programs, and the results are tabulated below. (These results are not included in the “number of participants” shown above, nor in the calculation of the median or average score.) Most of the programs have different skill settings (thinking time), and this was set to the highest level within reason.* The scores and rankings, based on six specific problems, are not necessarily indicative of each program’s overall capability.

*I do not allow any setting that takes more than a minute to make a play. Time considerations are also used to break ties, i.e., if two bots have the same score, the edge goes to the one using less time. Tests are conducted on a 3.4 GHz CPU with 512 MB RAM, running Windows 98.

Congratulations to GIB (US), which surged to the fore once again with a fine score of 51, followed closely by Jack (Netherlands) with a respectable 49. If one wrote a song about bot results in my play contests, it might begin “GIB plus Jack, and the rest of the pack.” No other bot was even close. It is also curious that GIB stays on top despite its stagnant development (no improvements in well over three years) which must reflect on the brilliance of Matt Ginsburg. Now, if we could drag him away from his real work to play with toys again, GIB might mop up the bridge world.

Bots were less well-behaved this month (or my options were un-botlike), as many choices went off the chart. When a bot chooses a line that is significantly different from any listed line, it is noted as G (think “good”) if it has any merit beyond the worst listed option. On Problem 1, Jack won two trumps ending in hand and led the J, scored as 4. On Problem 2, Q-plus Bridge won A-K and A-K before exiting with a spade, scored as 7. The remainder, noted as H (think “hopeless”), are scored like the worst listed option (I’ll spare you the details).

On Problem 2, I was curious how many bots would bid 4 , recognizing the nicety of K-9-8-7-6-5 4-3 J-10-8 6-4, after partner doubles 1 NT and raises 2  to 3 . Stars were Bridge Baron, Micro Bridge, Q-plus Bridge and Bridge Buff. Surprisingly, GIB and Jack (the two best players) were chicken bidders (passing 3 ), as was Blue Chip Bridge. On Problem 3, I wondered if all bots would play correctly on the opening heart lead in 3 NT ( Q-3 opposite A-6-4). All properly put up the Q, but two fell from grace in the holdup: Blue Chip Bridge won the first round, and Bridge Buff won the second round.

HAL took a liking to my song idea and came up with a different version, now in Real Audio at its web site. I think it’s a rap tune: “Play with HAL, and be its pal; GIB plus Jack? Getcha money back!”
