Not that it is that important, but one option is to change this:

Nf3 {play 50%}

to this:

Nf3! {play 50%}

At least it will now know that Nf3 is a "play this move" move, even
though the percentages will not be used...  that is better than what
you have now which is basically no books.bin at all since no moves
have the ! flag.  The idea is to take any move with a non-zero play
percentage and add a !.  If you ever see a move with a play 0%, then
just put a ? behind that move which will prevent it from ever being
played.

Or, you can just leave it alone, since this is not that important a
match anyway. :)
