My tests were conducted on the same hardware (P3 733MHz). In Graz I ran on a P4
2.4GHz while other programs benefited from considerably faster machines (in
addition to parallelism). Additionally, in my tests I used fritz8.ctg for both
sides. In Graz I used a random generated book which resulted in very poor
positions for Falcon in almost all games.
