Types

type Board

type Board [8][8]string

type Game

type Game struct {
	Board Board
	Moves []Move
}

func MakeGame

func MakeGame(tiles string, moves []string) (*Game, error)

func (*Game) GetTiles

func (g *Game) GetTiles() string

func (*Game) MakeMove

func (g *Game) MakeMove(move string, isWhite bool) (string, bool, error)

MakeMove godoc The move parameter represents the moving of a single figure on board and should be in following format: (figure_char)(file)?(rank)?(capture_sign)?(file)(rank)(promoted_figure_char)(king_check_sign|checkmate_sign)?

The x represents that this move captures opponents figure and + at the end that this move is king check for opponent. (e.g. Qa3, Nxf3, Bxc4+, R3xa6+)

The move can also be a request for draw by containing only = (equals sign) or rejection of draw ! (exclamation mark)

This function returns following values (normalized move, is game won, error)

	Figure              string
