Hi Josef,

thank you for your feedback!

On the top right corner, there is a parameter called view. Under it, you can select the Relative Butler.

Relative Butler is explained at one of the dashboards at the very start.

So far I have only done Open Series - when the full database is published (at least I hope it will be), I can then publish it for Women and Seniors as well

You are welcome :)

I am really sorry that at this point I am not able to make an analysis based on card holding. This is soon to happen though - if not at this Championship, then on the next one for sure.

However, that still does not solve the problem of not being able to track down the bidding from each table. It would be interesting to observe, for example, how many times did it go well if a player has opened w2 red vs green with Jxxxxx, or how many times did the 12-14 NT did better than the 15-17 NT or 10-13 NT. Take those just for examples - I am sure many more important observances can be made. So far the only real way of tracking it is on Vugraph. Because of the coverage being only on 4 matches, I would say that the pattern is still too small.


This breakdown was supposed to base on the certain moment in the matches and player behaviour on certain types of boards and/or opponnets. My working theory was that the biggest gap between top teams (or top pairs if you wish) and the rest is created on the last boards of the match. I am still not sure how to prove this, but there are some ad-hoc examples that can be used in support of this theory. For example, take a look at your team profile and the scores you made on boards 10 through 16.

I am sure there are many other conclusions and assumptions that can be made based on the data provided, and that is the main reason I have provided it.

Hope you enjoy it!

You can find the relative butler by changing the view parameter to Relative Butler.

A tab has also been added, explaining the Butler views.

In the player corner dashboard, a new sumarize view was added. You can find your butler scores (sum, avg or relative) against team of any ranking and at any point of the tournament.

Hi Tony,

thank you!

I don't have it at this moment, but I am working on it. I still have some doubt about how should it be made, but talking with other bridge players, an idea has come up.

Relative butler= Your butler + Oppponnent butler

i.e. If you have scored +1,0 on a match against a pair that has -0,6 average, than your relative butler is 0,4 because your opponnents are likely to give away 0,6 IMPs per board, so your contribution is +0,4.

I am not sure if this is the right way to go, given the fact that there are pairs that have played only few matches, but they can be excluded (Opponnent butler in that case could be 0).

Any better ideas?

What keeps West from having
x
KQJ10
xxxx
Axxx

or a simillar hand. I could come up with more hands than this one in which 4x would be 200, 500 or 800 (in an example above), and 4 will still be down. Tell you what is keeping West from having it - slow dbl!

I think that East automatic bid on 4 would be a lesser crime than this one. When his partner doubled 4, his hand values can only be worse, not better.

I got the vulnerabilities wrong; NS are green, EW are red, if it makes any difference.

That being said, if 2s was doubled by opener, that would be penalty as well, even if opener has maximum 3 spades? That seems highly unlikely…
