In fact it is very successfull when it is out of book in the same book-line. I have seen it several times in some 100 game matches against S5 and Gambit. I guess you have seen it, when it lose a game it stops and update the learning and checks the auto232. I thought everyone in the ongoing tournament should try to play the same Colle-line in the ongoing tournament as it obviously was out of book in move2. Bertil
