The world's No.1 weiqi (Go) player Ke Jie lost the contest against his artificial intelligence (AI) rival, AlphaGo, in the third and also final match of the summit on Saturday. This match began at 10:30 BJT in Wuzhen, east China's Zhejiang Province, with AlphaGo playing the black and Ke white. Ke showed his brilliant weiqi skills as he said he will "fight till the end," though he lost his previous two matches against AlphaGo on Tuesday and Thursday. AlphaGo made the first "impolite" move as it did on Thursday – to put the black stone on the bottom-right corner of the weiqi board. It is a Chinese tradition that the first stone is usually placed around the top-right corner and this is what weiqi coaches always teach beginners.
