BOREL support page

BOREL is a very sophisticated hand dealing program written by John Lowenthal (1938-1999) and continuously refined by him from 1987-1998. It is really a programming language to describe bridge hands and one uses it to chose to include or discard hands from the generated random deals. Many of the best players in the world use it to look at the possible hands when they have a specific hand on a specific auction, in other words, a bridge simulation. You may see it referred to in old Bridge World Master Solver’s Clubs. Others use it for bidding practice on specific openings that they wish to practice. Teachers can use it to generate specific opening and responding hands for a class. As an example I include my script to generate strong 2 openers along with several other useful basic scripts. One of the advantages of Borel is that you can specify hands where the opponents will not bid at a specific level.


The version I am selling for $49.00 (most of the proceeds will go to the ACBL junior fund as per John’s wishes) may not be the most current version but if you buy it you are guaranteed an upgrade if we find a more recent version. We (me with Celia and Lia Lowenthal) will be looking for the sources to see if it can be modernized. The documentation has not yet been completely scanned in (up to chapter 5 now) so if you buy it we will email it to you later. There is enough in the README to get started. plus there is a command summary included.

In the meantime, we are recommending using a DOS emulator such as DOSbox to run it and I have included my Python script which prints hands from Borel generated files (BHG) files.

A number of basic scripts to generate hands are included. This is not a package for the technically challenged! It is best used by other programmers at this point or very computer literate types.

The release is a ZIP file, it will not install itself. You need to unzip into a folder on your C: (or other drive) and then read the file called README.txt to find out how to run it.
