/*
Package chess is a go library designed to accomplish the following:
    - chess game / turn management
    - move validation
    - PGN encoding / decoding
    - FEN encoding / decoding

Using Moves
    game := chess.NewGame()
    moves := game.ValidMoves()
    game.Move(moves[0])

Using Algebraic Notation
    game := chess.NewGame()
    game.MoveStr("e4")

Using PGN
    pgn, _ := chess.PGN(pgnReader)
    game := chess.NewGame(pgn)

Using FEN
    fen, _ := chess.FEN("rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1")
    game := chess.NewGame(fen)

Random Game
    package main

    import (
        "fmt"
        "math/rand"

        "github.com/notnil/chess"
    )

    func main() {
        game := chess.NewGame()
        // generate moves until game is over
        for game.Outcome() == chess.NoOutcome {
            // select a random move
            moves := game.ValidMoves()
            move := moves[rand.Intn(len(moves))]
            game.Move(move)
        }
        // print outcome and game PGN
        fmt.Println(game.Position().Board().Draw())
        fmt.Printf("Game completed. %s by %s.\n", game.Outcome(), game.Method())
        fmt.Println(game.String())
    }
