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 Blue Chip Bridge, which not only topped all the bots this month but was the only bot to beat the average human score. Well done for a difficult set of problems. Of course, I also must congratulate HAL for its month-to-month consistency — some things in life are uncertain; HAL isn’t one of them.

As usual, several of the bot calls went off the charts, and a few were even amusing. On Problem 1, GIB went for the gusto with a jump to 7 , and Q-plus and Finesse Bridge found strange bids of 4 and 5 , respectively. On Problem 3, Bridge Baron evidently had an aberration using Blackwood, or maybe it was just mad because I forced it to bid 2 with A-K-J. On Problem 5, Finesse Bridge managed only a feeble raise to 3 , though I suppose one could argue it has tactical merit.

Problem 6 also had its rebels (indicated as G). Bridge Baron chose the wimpy route, overcalling 1 and then bidding only 2 . Bridge Buff took the other extreme, doubling and then bidding 5 . Talk about a difference in evaluation! While these and other aberrant choices might deserve zero, my policy is to score them equal to the lowest award among the choices offered because the bots are not programmed for the multiple choice format.
