Looking at Rebel's book by playing against it and finding the important lines for a new program is clearly easier than what jeroen did and I believe that it can be done in one year(not that I plan to do it). There are 2 reasons for it: 1)I believe that Jeroen's work includes lines that he analyzed and decided not to put in Rebel's book. 2)part of the lines in Jeroen's book are irrelevant for another program. If your program always starts with 1.d4 then knowing the good lines for white that starts with 1.e4 or 1.Nf3 is not relevant. Uri
