Undoing a move pushed to chess.Game?

[ArmanMaesumi]

I would like to use this Go library for an AlphaBeta pruning look ahead algorithm, but I don't understand how to neatly undo a move. Say we pushed a move to a game like so

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

How can we then undo the last move that was made?

You can use the position.Update method to move from valid moves directly and skip redundant validation: https://godoc.org/github.com/notnil/chess#Position.Update

Hope this helped.
