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 GIB, which topped the bots with a fine score of 53, and was the only bot to beat the average human score. On Problem 1, it was especially enlightening to see GIB come up with 4 S (slam try after opening a 10-point hand), the kind of bid that requires vision beyond that of a typical bidding database. GIB also continued to reach the laydown slam. Bridge Baron was the only other program to make a move over 4 H; alas, it stopped in 5 H. HAL tried to steal the slam by passing 4 H and then adding 120 to a 60 partscore. Sorry, HAL; it doesn’t work that way. HAL didn’t take the setback lightly, and I nearly got electrocuted in the process.

On Problem 5, Bridge Buff had no option but to interpret 2 NT as Jacoby (spade raise) so its rebid was always 3 D to show a singleton. To be fair, I tried switching the spades and diamonds to create a 1 D opening, and gave North a similar 14-count. It now responded 2 NT naturally; alas, South raised to 3 NT, missing the 33-HCP slam.

Q-plus Bridge also had a hang-up on Problem 5, insisting on jumping to 4 H over the natural 2 NT response. Out of curiosity where this might lead, I let it continue: North bid 4 NT (apparently reading 4 H as a mountain); South answered 5 H (must be two aces); but that was the end as North passed. OK, so there’s room for improvement. I’ll bet you missed a slam once, too.
