about me

I am a math professor at the University of Chicago who played more bridge when I was younger (became LM when I was 22 in the late 1970s) but have played only infrequently in the last twenty years.

Watching Videos of F-N from Opatija
One thing that has been learned from watching other videos prior to 2014 is that the behavior of F-N depends on the nature of the screens and perhaps other factors at the site. The screens used by the ACBL are not the same as those used in Europe, so, for ...
Another Question for Mathematicians--well...Statisticians
Leonard, It is close to accurate if you assume a normal distribution. The main error in the approximation is the assumption of a normal distribution --- it should be close, but how close?
Another Question for Mathematicians--well...Statisticians
Richard, you are correct; I was trying to simplify and when one does one often is not precisely correct. I also don't know what "random" events are used in generating the seed for the ACBL program. Also, this post was about the distribution of the cards so I was ...
Another Question for Mathematicians--well...Statisticians
The P in PRNG stands for pseudo since the algorithm is not exactly choosing things "at random", that is, with exactly equal probability for all possible hands.
Another Question for Mathematicians--well...Statisticians
Typo: "Out of 100K" should be "Out of 10K" above?
Another Question for Mathematicians--well...Statisticians
Standard deviation is used for the average of samples taken from skewed distributions. The number of samples needed to make this reasonable depends on how skewed the distribution is. One does need care, however, because the normal approximation often gives incorrect answers about unlikely events. In this case, a normal ...
Greg Lawler's bidding problem: Q AJ86543 KJ2 K9
Let us assume before. However, I don't think this would affect your decision to bid 3 (to pass would give too much away). I do believe that if might affect your partner's decision to bid 3, the fact that he knew that you knew he had ...
Question for Mathematicians
Any estimate would have to take into consideration the fact that your partner passed and to do this one needs to know your methods and tendencies (aggressive or conservative) over 1N.
District 9 (Florida) GNT final
When one thinks of this, it is amazing. If no one else wanted to play them, I would think that the opportunity to play them for a day would be great even with little chance to continue. This would be like a lesson in bridge for the price of an ...
What's going wrong with Gatlinburg ??
I have not been to a regional that was not in walking distance from me for over twenty years. I don't know how many people there are like me who like bridge (as a hobby, not a job) but realized a long time ago that masterpoints meant nothing. Let ...
