Chess opening book: Arena Big Daddy Book v4 (abk)


ABK, (Arena's book format) - the opening book format of Arena. It persists a book tree as array of entries, each entry referring one book move with priority and statistics, an entry index of the next move inside a book line (> 0 if any), and an entry index of a possible sibling move (>= 0 if any). The sizeof of an entry is 28, the initial position indexed by 900.(ChessWiki).

Arena Big Daddy Book v4 STP - this is a very large debut book (over 2 GB when unpacked) that will work well in GUI Arena.
