Unfortunately, I'm thick as a brick on book files, but I gather from the above that Andres will have a different EPD line for EVERY SINGLE POSITION in his opening book?? "Holy Crap!" I infer the advantage is it detects all transposed positions, and the disadvantage is it makes for a HUGE file. Andres, are you breaking this up into multiple files? Dann (and y'all), would you comment a bit on this scheme? I'm guessing that the text lists of the moves is the most common layout for a book file? Is this also a popular layout for an opening book, or is it only suitable for small books, etc.? Thanks, Dave
