Just like the marketing story that in a 12 stone double rook endgame deep blue managed to keep a draw because every move was perfectly played thanks to an incredible big endgamedatabase. In fact marketing department said something even more overreacted, 30 seconds after the game had ended in a draw. It's here just like that too. Those GMs didn't even have the time to prepare caro-kann further than move 5, let me assure you that. 4000 bookmoves that's something very very tiny! Also you enter 4000 bookmoves eyes closed in 8 days. Kure told he usually enters around 2000 bookmoves an hour. So for the experienced openingsbook creators here, 4000 bookmoves is just 2 hours. That typically describes the contribution of the GM's to the openingsbook. Hsu always believed in autogenerated books. Only in october 1997 that believe was interrupted rudely by Kure who with a very poor program, managed to score many points, just based uponb ook. - he still does Best regards, Vincent
