Is this faulty learning then? How do the testers from SSDF do it - do they disable the learned information before the start of the next game? Programs seem today to have many different parameters that effect their playing. As long as the testers say what those settings are it seems ok to me that they play to their hearts content and post the games as well. As one example, Thorsten's summer tournament was his do do as he wished but I still think he should have had an asterisk beside Rebel 9, stating that not all of Rebel's games were played using the default book settings. He could choose whatever setting he wanted as long as he shares those settings for us who enjoy playing over these games. > >So I will do the following: >1.
