I am not talking about autoplayer-games with commercial versions. i am talking about secret-small books in preparation for tournaments like e.g. dutch-championship. e.g. i saw a nice opening in patzer-quest: [Event "DOCCC 1999"] [Site "Leiden NED"] [Date "1999.11.06"] [Round "07"] [White "Patzer"] [Black "Quest"] [Result "0-1"] 1.d4 Nf6 2.a3 d5 3.c3 Qd6 4.e3 Nbd7 5.Nf3 e5 6.c4 e4 7.Nfd2 c6 8.Nc3 Be7 9.Be2 Qe6 10.Qc2 O-O 11.O-O a6 12.f3 exf3 13.Nxf3 h6 14.cxd5 cxd5 15.Bd2 b5 16.Bd3 Re8 17.Bf5 Qb6 18.Ne5 Nf8 19.Be1 Bd6 20.Bg3 Qb7 21.Rae1 Bxf5 22.Qxf5 b4 23.axb4 Bxb4 24.Bh4 N8h7 25.Kh1 Rac8 26.Rc1 Rc7 27.Kg1 Ba5 28.Bg3 Bxc3 29.Rxc3 Rce7 30.Ra3 Ne4 31.Bh4 Rc7 32.b4 Nhf6 33.Bxf6 Nxf6 34.Rb1 Ne4 35.Raa1 Nd6 36.Qf3 Nc4 37.Nxc4 Rxc4 38.Ra4 Re6 39.h3 Rf6 40.Qg3 Rc2 41.Kh1 Rg6 42.Qf3 Rgxg2 43.Qxg2 Rxg2 44.Kxg2 Qb5 45.Ra2 a5 46.Rb3 axb4 47.Rab2 Qe8 48.Kf2 Qe6 49.Rxb4 Qxh3 50.Rb8+ Kh7 51.R2b7 Qh2+ 52.Kf1 Qg3 53.Re8 Qf3+ 54.Kg1 h5 55.Rb2 f6 56.Re7 Kh6 57.Re8 g5 58.Rf2 Qg3+ 59.Rg2 Qe1+ 60.Kh2 g4 61.Re7 f5 62.Re8 h4 63.Rb2 Qf1 64.Rh8+ Kg5 65.Rg8+ Kf6 66.Rg2 Qf3 67.e4 Kf7 68.Rg5 0-1 The result is a loss against Patzer. I don't think patzer had a bad opening preparation. i like the line it played. That is exactly what i talk about. It did not work THIS time, but maybe the reason is that quest is stronger. don't know. but this is a good example... > There is only one possibility from each position >instead of multiple possibilities from a wide book. Of course the only way to >keep your small book "unknown" is to make one every time you play a game. right. before EACH round you have to change the book. with CSTal-dos it was very very easy to create a book out of pgn-data-. Before each round of the aegon tournament i went to the internet machines in the tournament hall. I searched for games of my next opponent, studied the openings he liked and downloaded special data-material from the web. than i melted an opening book, and edited it by hand. i melted it with a depth of not more than 10 plies ! i could have melted it with as much as i liked , but imo this is senseless. it is much better to let the engine find the way. >Jim Walker thanks for your opinion.
