I used a frequency of occurrence scheme weighted by the strength of the player so that the book will prefer moves played by stronger players when all else is equal.
There are 267489 position and they are based on the week in chess games. I do not know how good this book is and I have not evaluated it nor have any of the moves been hand picked.
