What exactly is a "killer >book"? It sounds like something good, but then I read on one of the posts that >someone was accused of having a killer book. In my neighborhood, "killer," >when used as an adjective, usually describes something good. I think this is a good question as perhaps everybody has its own definition for a killer book. Here is mine... #1. A killer book is a special designed opening book with pre-defined opening lines to play against several other computer opponents. A killer book contains lots of prepared (home work) games against other computer programs to leave the book in a clear won position. Or in other words a killer book is a collection of games that immediately after leaving the opening book reaches a position that would make a grandmaster resign without further playing (or reach an evaluation of +3, +4 or similar). #2. Another word used for "killer book" is the term "cooked book". #3. Killer books are common practice especially on comp-comp tournaments but also can be found in commercial chess programs although these days you hardly see them anymore, this since book learner was introduced a few years ago. #4. Other people have other definitions of a killer book. Some even say that when a computer program leaves the book with a 0.50 score (half a pawn up) that's a killer opening line too. #5. Killer books have a bad name because the work (beating the opponent) is not done by the chess program itself (the engine) but by the work of a human at home. - Ed -
