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 total score, the edge goes to the one that took less time. I conduct the tests on a 2.0 GHz CPU with 512 MB RAM, running Windows 98.

Congratulations to GIB, which returned to form with a narrow win over Blue Chip Bridge. The only other bot to top the average human score was Q-plus Bridge, but Jack was only a point back. All of the bots, however, had at least one score that would send them to the piranha tank — which is actually good news as they might electrocute the buggers before the people arrive. Even so, Blue Chip was spared when the piranhas threw it back — didn’t like fish and chips.

As usual, several lines of play went off my chart.* On Problem 1, Blue Chip Bridge immediately led a spade to the 10, which clearly deserves no more than the worst award of 2. On Problem 4, Bridge Buff won the second spade and cashed K, A, rendering the endplay impossible with hearts still blocked — but certainly better than an immediate club lead, so I gave it 3. On Problem 5, Micro Bridge tried to cash the Q immediately, and Q-plus Bridge drew one trump then led the Q to the ace — either of which is lucky to receive the same 2 points as Line C.

*If a bot’s line of play is unlisted, I substitute a listed line if the difference is trivial or negligible. If the difference is significant, I indicate it as Line G and score it appropriately, but the award cannot be lower than the worst listed line. This is only fair since the bot would have chosen something else if it were aware of the multiple-choice format.
