I am one of those who are waiting eagerly for your comments
on the games.

In particular, concerning game 1, Lee Sedol made a comment which
I do not understand:
> The right side white 1 (R10, 102nd move), which is often denoted as AlphaGo’s

Is 102.R10 really so special? I analysed that position with CrazyStone2013
about 30 times (independent runs). In 20+ % of the runs, CS2013 also wants
to play R12 (giving White 60+% chances of winning). But also in the other
cases, where mostly R14 or P17 are proposed, the expected winning chances
for White are given by about 60 %.

I would indeed like to know which % AlphaGo gave White in this position.

Kind regards,
