Hi - Fritz8 and Shredder8 color-code moves in the book window. What do these colors mean? The Shredder 8 .hlp file does not address this, showing an obviously old screen-shot with no color coding. Many cases (where N is big) seem obvious: Green=good, Blue=not good, Red=bad - but gurus pls feel free to say so if what seemed obvious isn't actually so. But when you get to the less obvious cases where N is small (few games in database used to build .ctg file) the small number of candidate moves tend to turn to Black. What's Black mean? In Shredder 8 if I've clicked the Optimize button in Book Options, and am using the un-modified shredder8.ctg book, and paste this line in [Event "?"] [Date "2001.03.21"] [Round "?"] [White "?"] [Black "?"] [Result "*"] 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be2 e5 7. Nb3 Be7 8. O-O O-O 9. Be3 Be6 10. Qd2 Nbd7 11. a4 Rc8 12. a5 Qc7 13. Rfd1 Rfd8 14. Qe1 Qc6 15. Bf3 h6 16. Nc1 * then there are plenty of examples of all colors. With both Prob and % at 100 it looks like 15... h6 would be played instantly from the book, but what happens if Shredder is looking to play white's move 16? Candidate move Nc1 is color-coded Blue, and has Prob=100 and %=0. Does Shredder start calculating instead of playing Nc1 from the book because there is no Green move? Are there any simple rules like: If Optimize has been done, Shredder/Fritz will play no move unless it's Green? I just guessed at that one, but you get the idea. I'd love to hear any such simple truths regarding how to understand the colors in the book window. thanks, Bruce ps - I did try to search using the CCC search button at this forum, came up dry, and on google as well. Found an old t-note at chessbase.com http://www.chessbase.com/support/support.asp?pid=86 with some but not enough info on Frits6's book window. I tried guys, pls be gentle.
