Though the theory is true here, reality is that the lines are so well prepared that it is very unlikely that a mainline prepared will be refuted. So you can keep playing the same, as it keeps winning. I hope you realize that i just lost sidelines this tournament. Not a single mainline. So you fix that sideline and can keep using the rest of the secret and very strong tournament book intact. How i saw leiden knowing a world champion is coming, is not important here. Important is that if you have just one line so well prepared, that it is very hard to play anything else. That's what even fulltime professional grandmasters do too. Seldom they have prepared more than 1 openings line that well. And usually to every move just one response. That's how i play chess myself, though i'm not saying chess engines should do it. The difference between playing some random other openings line is that if you play a random PGN line you have a 90%+ chance to get in a very poor line against strong bookers like Kure and Ochoa. Necchi and Noomen work less systematic than those 2 guys, which doesn't say a thing about whether they are better or worse. I'm not sure who makes the junior tournament book, but it made a very strong impression to me especially in 2001. Because they just show up 1 tournament a year, it's harder to effectively see things. This dutch tournament i was so lucky to have someone help me operate DIEP, so i could regurarly walk around and take a look to board positions of other programs. Best regards, Vincent
