Chess - Programming - Polyglot Book Format - Polyglot Book Format

A PolyGlot opening book is a collection of triples (Key, Move, Weight).

Key is a 64-bit Zobrist hash key, of a Board position.
Move is a move that can be made from that position.
Weight is proportional to the probability the move should be played.

struct entry_t {
   uint64 key;
   uint16 move;
   uint16 count;
   uint16 n;
   uint16 sum;
};
