;B[jh]
;W[ci]C[Magnificent! Black doesn't have any good response here. AlphaGo has probably calculated all possible variations locally.]

;W[eq]C[At this point, black is already behind. From those two games before, it shows that AlphaGo usually choose the safest approach, even by sacrificing some points, when it is leading. However, it seems hardly possible to turn the game around for human when AlphaGo is leading.]

;B[qe]

;B[rd]
;W[pe]C[This is a typical crude move which you get told off by teachers. However, AlphaGo just played it to simplify the game, I cannot help but revise some of our traditional concepts. ]

;B[go]C[Quite surprising that black created a ko here. White's territory should have been safe between two human players. My guess is that AlphaGo is again playing the safest way in order to simplify the game.]
;W[gr]
