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 have 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.

*I do not allow any setting that takes more than a minute to make a play. Time considerations are also used to break ties, i.e., if two bots have the same score, the edge goes to the one using less time. Tests are conducted on a 2.0 GHz CPU with 512 MB RAM, running Windows 98.

Congratulations to Jack, which equaled the highest bot score ever with a whopping 56 — and it needed every bit of it! Runner-up GIB was right on its tail with 55. Two great scores on a difficult problem set, as evidenced by the rest of the pack which was all over the court. This was by far the most dispersed distribution of bot scores — a spread of 39 points (not counting my implant HAL). I’m not sure what to make of this, but I wouldn’t be surprised to hear that Joel Cairo had been lurking around the computer room.

A lot of choices went off the chart* this month, and in most cases it was an obsession to lead trumps. On Problem 1, Blue Chip Bridge, Bridge Buff and Micro Bridge all led a low spade first; on Problem 3, Bridge Baron and Micro Bridge immediately won both of dummy’s top trumps; and on Problem 4, Micro Bridge won the first trick and cashed the A with A-10-9-7-2 opposite Q-J-8-6. Hmm. According to the Fat Man, I guess you just can’t trust those bots.

On Problem 5, Blue Chip Bridge and Bridge Baron won the A and A then led the 2; and on Problem 6, Blue Chip Bridge took a devious route, winning the second heart and cashing A; A; K; A; K. I have no idea what this was all about, but HAL was impressed — probably because it never won that many tricks on the same deal, let alone in succession.

*When a bot chooses an unlisted play, I substitute a listed play if the difference is trivial or negligible. If the difference is significant, I label it as Line G (or H if needed) and score it appropriately — but never lower than the award for the worst listed line. None of the Line G’s this month deserved any special merit.
