Moby Dam always leaves old information in, only appending new information to the end.
I looked sadly still the same.

C:\mobydam\mobydam.exe -b book\book.opn -e C:\damend
and try again.

Thank You Harm. I have a question. Is it possible to play a program like you at the Olympics.

- how to set the time in the program, eg. 20 minutes for 75 moves
- what you need to do to program began playing white
- what you need to do to program began playing black

In the second screenshot of http://hjetten.home.xs4all.nl/mobydam/mobydam.html
showing Dam 2.2, you can see how to setup the moves and time per game,
and which side plays which color. This is how I used it in the Computer Olympiad.

And now, how to do automated play on 2 computers.

Computer 1: start Moby Dam.

Computer 2: start the other program.
It can be Dam 2.2, Horizon, Dragon Draughts, or any other program designed to act as DamExchange Initiator.

We'll take Dragon Draughts as an example.

- choose menu item Window - DamExchange
- click the button Connect to other program
- in the dialog, enter the computername of Computer 1 into the field IPaddress/hostname, leave Port number at 27531, click Continue
- look at the Damexchange window (it may be hidden behind the main window), it should say: Connected to computername:27531
- click Settings and enter number of moves, time per game, etc.
- click button Single game or Match, as desired.

Thank You Harm. To program played white is I have to run as follows:

- run the program Moby Dam
- run the program Dam 2.2.7
- choose Game - DameExchang - Make connection
- in the next window Dam click on OK
- in window DamExchange appears inscription Winsock startup completed. Trying to connect to 127.0.0.1 at port 27531. Select notification: FD_CONNECT.
- choose Game - DameExchang - Start Game
- in the window Dam write:
time to play - minutes
number of moves per game - moves
option - This side plays - White - Black
Name: The name of the program

If the program Moby Dam to play this white mark the on the color game Black.

If you want to play black this program we do it as follows:

- run the program Moby Dam
- run the program Dam 2.2.7
- choose Game - DameExchang - Make connection
- in the next window Dam click on OK
- in window DamExchange appears inscription Winsock startup completed. Trying to connect to 127.0.0.1 at port 27531. Select notification: FD_CONNECT.
- choose Game - DameExchang - Start Game
- in the window Dam write:
time to play - minutes
number of moves per game - moves
option - This side plays - White - Black
Name: The name of the program

If the program Moby Dam to play this black mark the on the color game White.

One very important note. It must be enabled Player-Player.

It's a shame that the program supports multi-core parallel search.

I see. Change the shortcut Element docelowy to:
C:\mobydam\mobydam.exe -b book\book.opn -e damend
(without the C:\ before the damend)

Harm thank You. Now it is all right. When can we expect new versions of the program.

Hello,

Thank you very much for providing this program.
I'll get following error when compiling on linux:

make
gcc -g -O3 -Wall -march=nehalem -flto -DPF -DETC -DLMR -DKIL -DCFLAGS="-g -O3 -Wall -march=nehalem -flto -DPF -DETC -DLMR -DKIL" -c dxp.c
dxp.c:1:0: error: bad value (nehalem) for -march= switch
/*
^
make: *** [dxp.o] Error 1

How can i solve this problem?

gcc versions before 4.9 don't recognize the -march=nehalem option.
You can replace it in the Makefile by either -march=native (optimizing for your particular processor model)
or by -mpopcnt.
