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).

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.

*More specifically, I do not allow any setting that takes more than two minutes to make a play. I conduct the tests on a 2.0 GHz CPU (512 MB RAM) running Windows 98.

The British are coming! A spectacular showing this month by Blue Chip Bridge (a recently updated version) portends a challenge to perennial champ GIB. Blue Chip’s fine score of 53 would have made the top 25 in the human ranks. Not too shabby! I was especially impressed with its defense on Problem 6, being the only bot not to cash all the spade winners. Blue Chip is currently the top bot in my bidding polls, and it might just be aiming for the whole ball of wax.

The only other bots to beat the average human score were Jack with 43, and GIB with 41. Jack is relatively new to my testing and seems to be another challenger to GIB’s dynasty. It will be interesting to see how the sparks fly in the next few contests.

Speaking of sparks flying, the makers of HAL filed a libel suit in the 14th District Court, and I was served with a subpoena last week. The lawsuit claims that my “cruel and biased comments” have brought their sales to a standstill. Come on! I would never write anything derogatory about a computer company — even a crap box like HAL. Thanks to Paladin’s winnings, I was able to hire Johnnie Cochran and Robert Shapiro, who are confident we can beat this thing.
