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.

*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 eked out a 1-point win this month in a three-way photo finish. Grouped at the top were GIB with 44, and Micro Bridge and Jack, each with 43. No other bot beat the average human score.

GIB’s win was more solid than the 1-point edge would suggest, as I checked its follow-up on the two 10s received (Problems 1 and 5) — right on the button each time. Micro Bridge, however, scored the same 10 on Problem 5 but failed to make the contract. Jack had no 10s, so I guess it earns the consistency award. Bridge Buff scored 10 on Problems 3 and 5, but only the latter was followed up correctly. Bridge Baron scored 10 on Problem 1 and followed up perfectly.

As usual, some of the bot choices went off my chart. Choices shown as H are best forgotten (think “hopeless”) and scored equal to the lowest listed award. Choices marked as G are fair (or at least better than some listed options) and scored as follows. Problem 1: Bridge Buff and HAL (are you kidding me?) ruffed and won the K, two spades, then ran diamonds (4). Problem 2: Jack, Micro Bridge and Blue Chip Bridge won the K and cashed one or two diamonds before ruffing a heart (5) which struck me as a change of mind in midstream. Problem 5: Bridge Baron won the Q, A-Q with a finesse, and ruffed a spade (5) which is the same as the winning line but forgetting the diamond finesse.

I’m not sure how HAL did it, but it found a way to undermine my entire database. Amazing. Some stupid message scores higher than HAL does from month to month. I’ve traced the malicious code to its motherboard, but the last person who futzed with that was electrocuted.
