I'm just going to cross my fingers and hope. <grin> Of course, even if I do get them all in, not catching transpositions is going to be a serious bummer. Hopefully I can edit the compression level after the import is finished (maybe move it a few moves up at a time) and the software will reexamine the book that has been built without going into swapland. I think I'm being overly optimistic though, first the import has to finish. :) Bob, do you have any tool to take the learned information (presumably keyed by hash value and learning score) and provide a line of play from the start position that reaches it? Incidentally, here are a couple of games in the "wall" book that need some correction: Game #128155 (or so :) White is "Wahls, Matthias" Black is "Bancod, Ronald" Result is "1/2-1/2" in the headers but 1-0 in the game score. Search for the string "45. Ke2 Ra2+ 46. Ke1 Na3 47.Re5+ Kf6 48. Rf5+ Kg6 49. Rxf4 1-0" to find it. Game #139452 (or so :) White is "Curdo, John" Black is "Kavalek, Lubomir" Result is "1/2-1/2" in the headers but 0-1 in the game score. Search for the string "16. Nxe4 c5 17. Nxf6+ Bxf6 18. Bxf6 Qxf6 19. Qh5 g6 20. Qxc5 Qc3 21. Qd6 0-1" to find it. There was an error around game 32000, but I missed it. Note to author of CDB: Mismatched result was the cause of the 'error' I emailed you about. CDB detected the above errors, and also any additional ones that I might come across in the remainder of the book that might be posted in the next day or so. Dave Gomboc
