Howard, Q5T is simply Eric Campos' winner of the tactical testsuite contest From Rebel but Attractiveness was increased from 200 to 250. That is the only change. ECTool Century 2.0 owners can download the settings from Rebel Subscription Area but as they are stored there they work but can't be opened in the special "Personality Editor". Changes can also be made with editors like Notepad or WordPad. As you mentioned before small changes in Attractiveness can produce really different moves also because of the interaction with King Safety. That was also the reason, I thought, that the default for Attractiveness is 101, not 100 because that interaction only begins for values>100 and not 100 or below. Not sure but somebody asked that a while ago. If you would like to try the settings please tell me if you have any comments! The more critical the better because I am still trying to see if there are any better settings "nearby". Your remarks deserve going deeper into them I think but it will have to wait a little..

Gameplay does not seem Q5T's forte, for the reasons you mentioned, also it is too "impatient" you might say, for that.
