And once out of >book the situation is mostly clear enough to find the obvious plan. In most of the cases movei that has almost no knowledge can find the theory moves by itself. I can imagine that engines with more knowledge in the evaluation may find in more than 99% of the cases the right move and if the average length of the book is 20 moves then it means that only in 1 out of 5 games they are going to do a book mistake. I do not think that the idea to use book only for learning to avoid playing a line you lost or to repeat wins is so bad. The engine may ignore a big book if the following 2 consitions happen: 1)the position never happened in the past 2)the position is not in a small manual book. Uri
