The program dealer can be used to generate hands for partnerships bidding
training or for generating statistics that can be used to design conventions,
or win postmortems.
Running the program involves 3 steps. First, the user has to write an input file
containing hand-descriptions and action. A very simple example would look
condition shape(north, any 4333 + any 4423) and hcp(north)>=19
The first line specifies a condition for the north hand, in this case, a hand
with 4333 or 4432 shape and at least 19 high card points. The second line
tells the program to print the 4 hands. The program reads from standard input,
so in principle, it is possible to enter the conditions directly into the
program. Using a file is a lot more practical though, as it allows the user to
re-use conditions and fine-tune the conditions.
Then the program has to be run, it reads the file, looks at the various command
line switches and then produces a number of hands. The output appears on the
screen but can be re-directed to a file.
Finally, the user has to look at output and analyze the produced hands.
Alternatively, the output can be used for a playing program.
- Exhaust mode (alpha version).
- -g number
- Maximum number of hands to generate (default is
- -l number
- Instead of shuffling, deals are read from the file
library.dat by M. Ginsberg (see ). When using this, the tricks()
function is quite fast and bridge.exe from GIB is not used.
- Shows a progress meter.
- -p number
- Maximum number of hands to produce (default is 40).
- Suppress PBN output (useful for testing, then switch it
back on when generating the "final" sample).
- -s number
- Uses number as the seed for the random generator, running
the program twice with the same seed will produce the same sequence of
- Select uppercase for the symbols "AKQJT" (default
- Toggle verbose output, prints statistics at the end of the
run (default is on).
- Emit a version-identification string and exit.
- Help, prints the syntax.
- No swapping, each deal is generated normally (shuffling)
- 2-way swapping, after each shuffle another deal is
generated by permuting E and W, leaving N and S in place (NB: not fully
compatible with predeal).
- 3-way swapping, after each shuffle another 5 deals are
generated by permuting E, W, and S every which way, leaving N in place
(NB: not fully compatible with predeal).
I would prefer if you did not
use this program for generating hands for
tournaments. I have not investigated the random number generation closely
enough for me to be comfortable with that thought.
