I posted an analysis about the book battle in this match about a week ago - in the match Junior-Crafty there was no book advantage for Junior at all, to the contrary in fact. An extemely short summary: Junior never reached any advantage with the white pieces and though the black side was not bad at all, it had to suffer from 1.5 book losses too. I don't believe Junior's book is so great at all. As posted before Crafty should have played a wider repertoire and try to get its opponent out of book earlier in general IMHO - but with your tournament book you would probably do the opposite, narrow it down even further. I don't think this would be to Crafty's advantage, but I probably won't find the time to do a test during the next months. Peter
