The last released version of Junior or shredder or tal were never number 1. Junior4 was never released but it did not help it to be number 1. The versions of shredder and tal were not tested by the ssdf testers or were tested as annonymous programs and could not be number 1. In the last years except fritz only hiarcs and chessmaster were number 1 and had only a small advantage(not 25 elo rating advantage) and the advantage of tiger could be bigger if it used aggresive learning(trying to repeat won games) Uri
