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 bidding 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 had different skill settings (thinking time), and this was set to the highest level. The scores and rankings, based on six specific problems, are not necessarily indicative of each program’s overall capability.

Congratulations to Q-plus Bridge, which topped the competition this month with an excellent score of 50. The only other bot to beat the average human score was Micro Bridge, taking second place with 47. Bridge Baron came a close third with 46.

Wild distributions proved to be a stumbling block for several of the programs. GIB’s peculiar pass on Problem 1 (with nine clubs) would seem like a tricky tactical maneuver if chosen by a human; but by a bot it suggests a flaw in its bidding database or hand evaluation. Similarly, on Problem 6, Blue Chip Bridge overcalled 2 C (with eight clubs) but then chose to pass on the next round (indicated as Choice H) rather than compete. Bridge Baron instead chose a bizarre Michaels cue-bid (indicated as Choice I) with 8-4 shape.

For scoring purposes, unlisted choices get the same award as the lowest listed choice. While some errant choices may indeed deserve zero, this wouldn’t be fair because there is no way to instruct the bots to my multiple-choice format. Ties in the bot rankings are broken by thinking time, with the advantage going to the bot that was faster.

Problem 3 might be considered unfair, as two programs (Jack and Bridge Buff) did not have the unusual 2 NT overcall available as a bidding convention; hence, they had no chance to receive the top award. Nonetheless, this doesn’t get my sympathy or any scoring adjustment because the convention is almost universally accepted. (I suspect it will be included in future versions.) Curiously, GIB preferred to overcall 1 H with 6-6 shape despite the availability of the unusual 2 NT. HAL, of course, preferred to bid clubs first, saving the heart suit for what it called a “high-level perverse.”
