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 Bridge Buff (Canada) which topped the bots this month with a respectable 49. GIB (US) was second with 47. Blue Chip Bridge (UK) and Jack (Netherlands) were the only others to top the average human score. I thought the scores would be lower this month because few of the programs apply matchpoint strategy, e.g., trying desperately for overtricks. Perhaps they just made a few good guesses, which never hurts for humans either.

As usual, some of the chosen plays were off my list. On Problem 1, GIB chose to cash one heart before ruffing two spades and a diamond (Line G) to reach an ending that might work if East had C K-Q-x, so I awarded it 5. On Problem 2, GIB won the C Q, ruffed a heart and led a diamond (Line G), certainly better than two of the listed choices, so I awarded it 4. On Problem 6, Micro Bridge and Q-plus Bridge chose strange play sequences (Line G) which were surely better than the absurd Line B, so I gave it 3. Other wayward choices (Line H = hopeless) are best left undescribed; it’s too close to dinner time.

Problem 4 required a routine unblocking play at trick one (S A-K-8-6-3 opposite J-10-9-5) and I was curious how many of the bots would do this. Ouch. All but two blocked the spade suit, effectively leaving no route to success. Congratulations to GIB and Q-plus Bridge, which had the wisdom to foresee this.

HAL had another fine score, and I’m not kidding! In the past, HAL rarely made double figures, but it recently became a Scrabble fanatic. Now, instead of doubling partscores, HAL only thinks about double word scores, so this month’s answers are just as bad as ever — in fact twice BAD. Nice touch, HAL.
