Functions

func MoveToPolyMove

func MoveToPolyMove(move board.Move) string

Convert move to UCI move in general, castling moves are converted to polyglot castling move format ie e1g1 -> e1h1.

func PolyZobrist

func PolyZobrist(b *board.Board) uint64

func UCIToPolyMove

func UCIToPolyMove(move string) uint16

Types

type Book

type Book struct {
	// contains filtered or unexported fields
}

func LoadBook

func LoadBook(path string) *Book

func NewPolyglotBook

func NewPolyglotBook() *Book

func (*Book) AddFromPGN

func (pb *Book) AddFromPGN(game *pgn.PGN)

func (*Book) AddMove

func (pb *Book) AddMove(key uint64, move string, weight uint64)

func (*Book) NormalizeAndOrder

func (pb *Book) NormalizeAndOrder()

Building a book from a large number of games can exceed the limits of uint16. Find entries where a weight exceeds this limit and normalize the whole entry.

func (*Book) SaveBook

func (pb *Book) SaveBook(path string)
