I can understand if you don't want your mailbox >stuffed, but I probably don't find more than 1 per month (on average). >WP No, Pls. feel free to send me any e-mails you want. I am improving the book often, but sometimes I need to see the bad lines come up to realize I need to make an improvement. As you know the amount of time needed on an opening book is so large, that we must refer to GMs as well to classify openings lines. Sometimes these values are wrong and computers or later analysis have destroyed those moves/lines. So, I am bringing to the next release all findings/refinements. Thanks in advance, Sandro
