Are there other known transposition bugs when using Bookbuilder? Is there some easy way to find games with these transposition bugs, after converting the book to pgn with bb36c. I open the pgn in Chessbase and convert to cbh format so I can do some searches. If I could find al games with these transposition bugs, I could delete these games. So only the games with the useful transpositions are preserved.despite some slight transposition
bugs as result of sometimes strange moves (eg Ng1f3 e5 Nf3g1 ?)
