I started with book cooking in about 95 by using several paper sources. Since 96 or so i also imported pgn-games with go to "novelty" so far, i analysed a bit and decided by myself whether i extend the book and the probability to play. I stopped extensive working on the book short after my short professional career in 97. Possible that the b4 line was considered Ok during this time? When does "Theory" found all the refutation lines? Unfortunately this line never came up in other events or in the few testgames with my new program since 2001. But doesn't even professional programs with professional book authors stumble over new theory, most likely in important events? Regards, Gerd
