继去年AlphaGo以4:1的成绩战胜李世石之后，最近一周在线上横扫围棋棋坛、四处挑战围棋高手并取得60连胜的神秘棋手Master终于揭开面纱，Google新版的AlphaGo。请看本报周五的报道：

    For the past week or so, a mystery player has been logging into online Go game servers and beating the world’s best. The player’s identity was revealed at last.

    It was none other than AlphaGo, the artificial-intelligence (AI) program that triumphed over Go master Lee Sedol last March in a widely publicized US$1 million showdown.

    报道中的showdown就是“决战”，例如：

    The two teams are getting ready for a final showdown.

    意思是这两支球队准备好一决雌雄。
