1. program A is down a point with last book move, has stronger search and beats program B. 2. program A is up a point with last book move, has stronger search and beats program B. 3. program A is down a point with last book move, has weaker search and losses to program B. 4. program A is up a point with last book move, has weaker search and beats program B. I know it must be lots of work to have a good book for programs. If program C shows up in last four tournaments with inferior book, and losses most games due to book, then we cannot know strength of search for program C in tournaments. Knowing and studying opening theory, has always been a big part of chess. In comp-comp tournaments, I would prefer to compare search methods with equal hardware, and starting from a "neutral position out of book". This way we are comparing search methods, time control, and eval between each program. Also it would seem that anyone that thinks they have created a comp "Book", for a program---I dont think you have. You have consulted 1000's of GM game openings, to put your book together. I am not saying that you havent worked your a__ off in what you think would make this a better book. I am saying, tell me the date you finished your book, and I will go back and search all your openings, and compare your book opening dates to previous dates all these openings have been played by humans. It would seem to me that the only opening lines you can take ownership of, would be a variation that you can prove has never been played. And to follow up this last point---if a GM studies his a__ off and finds a new opening line or variation that has never been played, uses this line, gains advantage, and mates Kasparov,,,this line will be studied and played from then on, will be in everyones book. if a GM that put in time to find a new variation, and proves it will work, he cannot protect his own creation once it is exposed in tournament play. it will take on his name, but that is it. how many actual lines have the program book authors actually created from scratch, that are not in any opening database, or have not been played by a GM? I like the idea, about putting in code that will allow another program to play an inferior line, but wont allow your program to play the same inferior line. this will protect the book that you have tuned for comp-comp play using someone elses opening theory. kburcham
