Does anyone know of a website which has tables which reflect the odds of a hands having a given number of hcp, given that your hand has x hcp, with a table for each value of x. For example, the odds of having exactly 10 hcp without any information about the other hands is 9.4%, but the odds of your partner having exactly 10 hcp is higher if you pick up your hand and see 5 hcp, and lower if you see 15 hcp.

By the way, there are tables of hcp and distribution probabilities at

I needed to do a similar type of analysis for some of my system notes.  I was not able to find a good web site that provided precisely the information that I needed.  However, I did find that many of the existing dealer programs were able to generate the information that I needed using Monte Carlo simulation.

I found setting up some simple scripts to be much easier than computing the conditional probabilities.

What dealer program(s) do you recommend?
1) A reply to a previous post recommnded that I create my own forcing club system, and I am attempting to do so. The simulation idea sounds good. I'm a programmer, but I want to avoid spending my weekends writing code.
2) Will these programs practice bidding with you? Do they mainly give you randomly generated hands which fit specified criteria?

I prefer Hans Van Staven's "Dealer", which is available as freeware.

The program doesn't have any kind of GUI.
What it does offer is a full featured Scripting language that I found quite intuitive.

The tables at Bridgeguys look like a copy of the tables in "The Official Encyclopedia of Bridge". There may be more tables in that, estimable, publication. There are certainly probability tables associated with "Suit Combinations".

Isn't the original question about biased "binomial" distributions?

It seems to me that, if you wish to set up such a "spreadsheet", DON'T use the Milton Work count? Quacks are over-valued... etc.
