Biased opening book by bjbraams: "Here are 1207 lines. The order is randomized, so if you need exactly 1000 lines then it is reasonable to take the first 1000 in the file. Hard criteria: dbcn eval in the range 80cp to 120cp, popularity in human master games at least 10 games per million. Soft criteria: shorter lines preferred, and final move not too unpopular." bjbraams_chessdb_1207_lines.pgn.xz
