Hi,

yes, of course but good books are not similar to fat books. You can have a very
good book with 1 million moves and with this system, it is very easy to go
through the book to find the right position and it is very fast. Either you can
only choose the first move for this position or all moves for this position but
it is very fast to do and undo moves, just some changes in the bitboard or in
the chessboard.
