about me

I am a Dutch bridge player from Amsterdam, but now temporarily living in Oslo with my girlfriend Meike Wortel. During daytime I am a theoretical mathematician working at the University of Amsterdam.

I learned to play bridge in the United States: first in Michigan, later on BBO. Bridge in the Netherlands was socially refreshing and systemically confusing. After 7 years I'm slowly getting used to the systemic issues.

Wouter Fitski's bidding problem: J52 T976 2 J8542
I believe that some recent world champions play that a direct 3S is weak.
Can Google's DeepMind beat the BBO Robots in 2017
Agree with Bob on both accounts.

You can easily allow any style you like.

Hi Csaba, I think that what you sketch is very good with respect to information leakage, but the gain in comparison with traditional methods lies mostly in the rest of the play, not in the opening lead.

Regarding the Qx doubleton, I didn't think about that. I didn't want to pick an extreme hand like AJxx xx KQxx xxx, where I think that bidding stayman would do much better, or xxxx AQ Kxxx Jxx, where nobody would be surprised if bidding Stayman would do poorly ...

You would have to make a choice regarding selecting the lead, yes. But for pairs it seems reasonable to just take the leads that give the maximal number of tricks. I understand the flaw you mentioned, but it wouldn't bother me. :)

I agree with you regarding the effect of putting the 4333's in 1NT-3NT. I wonder how large the difference will be though. I found that when ending in 3NT after both stayman and puppet stayman, regular stayman won by about 0.07 imps. This was an earlier study where ...
The Price of Information
I don't think that it is obviously more useful at pairs. Admittedly, very few things are obvious to me.
The Price of Information
Meike said she would put the code in a github. I don't know what that means, but I think it is what Michael asked for. When I have the time I will describe in this thread exactly which assumptions I made for those who are interested but prefer not ...
The Price of Information
1. It seems to me that it is best to use the same evaluation for selecting leads as the evaluation that is used in later steps. 2. I tried to explain something using as little lingo as possible without saying incorrect things. While I know very little about statistics, I ...
