It has been reported to me by almost all people who still take the time to play manual games that the results of Rebel differ significant playing manual or auto232. It is just a confirmation of what I suspected first, now proven by the introduction of the log-file. Also almost all manual events Rebel participated (manually) till now have been successful with the exception of the "Thueringen" tournament. But then in this tournament Rebel played with an untested personality and also in some games the "Playing Style" was set to "defensive" which is a disaster. Rebel Century 3 (manual) results (without Thueringen) are listed on: http://www.rebel.nl/r11-resu.htm Most German testers got the message and if they include Rebel in a tournament Rebel's games are played manually and I am most thankful for that. >Something is definitely >wrong with ssdf testing. The SSDF people do a fine job only that they should start to believe producers when they put something in the manual instead of calling them bad losers. But apparently producers are all liars looking for poor excuses if their baby does not perform well on their list. They don't even ask themselves the possibilty if they (maybe) could be wrong in their judgement. Ed
