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.

In many cases a bot’s actual line of play did not match any of the choices. If the play was effectively the same as Line A-F (e.g., a transposition of plays), that choice was credited, however, if the line was considerably off base (i.e., worse than any of the options) I indicated this by the letter G. For scoring purposes, “Line G” counts the same as the lowest of Line A-F (it wouldn’t be fair to score it zero because the bot would have guessed if it understood the multiple-choice format).

Congratulations to GIB, which returned to form after a brief slip to second in my last play contest. A fine score of 50, too! Second place went to Q-plus Bridge with a solid 46, and third went to Bridge Buff with 42, good enough to make the human listings. The performance of the other bots was poor this month, which I noticed seemed to be due to a propensity to draw trumps too soon — in fact, Finesse Bridge led trumps on every problem (a primitive playing algorithm I suspect) yet still managed to take fourth place. Fortunately, HAL has a more sophisticated algorithm: (1) Consider the bidding, (2) analyze the lead, (3) then, and only then, choose a nullo play.
