I'll be happy to ask Bob the next time we speak. He doesn't do email.

“Reasoning that W holds the ♣Q…”

What reason is that? Are you hypothesizing an auction?

Thanks for posting, Barry!

For those as confused by the names and schedule as I am, this is the quadrennial world championship tournament formerly known as the Olympiad.

Yes, though not “by the book.”

Anyone who's interested in the Kaplan-Sheinwold bidding system should check out the KS mailing list I started roughly 15 years ago and the KS system notes (circa 1972) hosted by The Bridge World magazine:

I'm glad you enjoyed watching, Richard. I'm confident my play was not flawless! We did do well that year, losing to the Fleisher team 227-219 over a 120 board match.

Our next date will be the Platinum Pairs in Columbus. We'd play more often but Migry is often booked for professional commitments, in both Women's and Open events.

Excellent Italian restaurant a 15-minute drive from the Marriott:

We boomers can play with one another. I'd love to see newer players of any age encouraged and welcomed, not just out of a love for the game but also out of self-interest.

Steve wrote “To derive single-player ratings, you need some formula for combining two individual ratings into a pair rating.”

I don't understand how this is necessary. Why not follow a similar procedure as the one used to calculate pair ratings? For each round, a player would have a matchpoint expectation based on his opponent's ratings and his partner's. As with the Elo system, if he exceeded his expectation his rating would increase, while if he scored below it his rating would decrease. If the formula were linear it could be calculated using his session score and the average of his opponents' ratings, useful if board by board data were for some reason difficult to come by and also easier to explain to the players.

This procedure illustrates one advantage of a rating system over a masterpoint system. A player could not, on average, increase his rating by playing with a stronger partner. Likewise, his rating would not be at risk when playing with a weaker one. Even better, players interested in improving their rating would be motivated to partner promising but underrated players.

Thanks for the votes and comments! I've posted the voting totals so far and the table results in the comments on my original poll here:

Thanks for the votes and comments!

Vote totals so far:

♠752 ♥AJT9 ♦Q4 ♣KQJ9 - Pass: 56 Double: 14
♠752 ♥AJT9 ♦K4 ♣KQJ9 - Pass: 28 Double: 24 2♣: 2

Note that the second hand is roughly two points stronger than the first:

http://www.jeff-goldsmith.org/cgi-bin/knr.cgi?hand=752+AJT9+Q4+KQJ9
K&R (752 AJT9 Q4 KQJ9) = 12.85

http://www.jeff-goldsmith.org/cgi-bin/knr.cgi?hand=752+AJT9+K4+KQJ9
K&R (752 AJT9 K4 KQJ9) = 14.80

I doubled with the first hand, as did the West at the other table. He went for -1400. I deserved the same but escaped for -140.

It was a head-to-head match, so there were two results!

I attempted to post a new poll last night but it does not seem to have taken. I'll try again now…

The consensus favors Pass, with 34 votes versus 7 for double.

I'll take Craig's suggestion and post a new poll with the Q replaced by the K.

Tomorrow I'll report on the result at the table!

If you can't find your District's recorder you can also send the form to the ACBL recorder at recorder@acbl.org

As to whether you should record any such incident, the answer is usually yes. Once you do the recorder can decide whether action is warranted.

Here are some other BridgeWinners discussion of rating systems. This is surely not a complete list!

2013 https://bridgewinners.com/article/view/acbl-technology-4-rating-systems/
2014 https://bridgewinners.com/article/view/power-ratings/
2015 https://bridgewinners.com/article/view/an-elo-rating-system-for-bridge/
2017 https://bridgewinners.com/article/view/big-ideas/

For what it's worth I still think any reasonable rating system would be a boon and well worth implementing, whether for players or pairs and for IMPs or Matchpoints.

Your recollection is incorrect, Richard (and Frances). From the October, 1982 article in The Bridge World:

“Indeed, we found that the count worked as well for one-bids as for two-bids, delicately mirroring the Editors' judgments of value. For a K-S player, an opening bid of one in a major or one notrump becomes possible at 12.0 points, mandatory at 12.5…”

Shouldn't BBO let you declare if partnering a robot?
