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 had 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.

Congratulations to GIB for winning in convincing style with an excellent score of 54. Curiously, GIB missed the best plays in the two 3 NT contracts (which seemed easier, especially Problem 1) but was perfect on all the others. I was particularly impressed with its execution of the squeezes on Problems 4 and 5, not only in the initial plays but carrying each out to fruition. Well done. The only other bot to top the average human score was Bridge Buff with a respectable 43.

As usual in my contests with multiple-choice answers, the bots often go off the charts with their actual plays. If the difference is trivial (e.g., a transposition of plays) or effectively the same, I give credit for the listed choice. My indication of “Line G” means the choice was not only off the charts but also inferior (or equal) to the worst listed choice. For scoring purposes, Line G gets the lowest listed award.

Once again HAL was dependable, never getting lost with Line G and always agreeing with one of my choices — well, my sixth choice, but who’s counting.
