You should be a bit careful: Different playing styles of the engines are no
guarantee for success. I remember one AGEON tournament, 1996, when I
participated with a 3-Hirn, using Rebel 7 and M-Chess-Pro 5. It became a
desaster! Rebel and M-Chess were too different (in those days): In my position
as controller I was not able to execute fine long range planning in the way it
had been possible with other tandems (like Genius3 & Fritz3, for instance).

Nevertheless, good luck for your project, and also for your
cooperation in general. The computer chess world benefits from the
two companies Chessbase and Millenium, but she also needs other
competitors like you are.     Ingo Althofer.
