Junkbase is too crappy for that. I use corrspondence games, filtered for strength. I use TWIC games, filtered for strength and time control (no simul, blitz, blindfold, rapid, etc.) I use SSDF games filtered for strength. >How long book lines can one expect? (polyglot options) I don't know. I sometimes experiment with line length and then forget what I did. For the really big book, I just let the filtering program decide. >If you want to keep it a secret ignore my post. There are no secrets. I will tell you anything you want to know.
