Book was 4000 handcrafted moves. So not given in by Benjamin.
Note those 4000 moves were not only benjamin but another 3 GMs
who contributed to it.

The move came out of an automatic generated PGN file, just like
crafty can automatically generate a book from PGN file.

4000 moves is not enough to even cover 1 opening.
