comment How does AlphaGo calculate?
The Deepmind website had the paper without a paywall, but it seems it was removed (or I missed it) - too bad!

comment How does AlphaGo calculate?
No, neither of them solves for complete solutions (If they did, that would mean the games were solved!). --- By the way, computers are "it", not "she" (even though the female form has mistakenly been propagated recently.)

comment What is the actual world ranking of Fan Hui
The cyberoro image is from open.cyberoro.com/photo/201407/%5B519386%5D140722-pj-04.jpg, but I don't remember the corresponding articles. I don't know anything about the WBaduk schema, sadly.

comment In go, is it possible to guess the opponent's strength?
@NathanThompson The score difference is a very good point (from many games, not just one, of course). I've heard of it with 7, 10 or 14 points instead of 20, it seems everyone uses a different metric there. Considering that 1 handicap stone equals 2 komi in theory, something around 14 sounded most reasonable to me, but I've never really thought about this.

comment In go, is it possible to guess the opponent's strength?
I'm not sure if there is a real answer to this question. Skill in Go is not a linear progression: You may be great at tesuji, but your fuseki may be terrible - or the other way around. And in particular, you often don't know that you're bad at something (thus cannot judge others correctly on that topic). --- That being said, I am currently working on a project which involves gathering evidence on this very issue, so maybe there is some kind of answer, after all.

comment Are shell and slate go stones fragile?
I have no sources except personal experience, but from that, it seems there is little practical difference between glass, yunzi and slate/shell. I wish I could justify buying slate and shell stones with their increased durability.

comment How do I chose invasion or reduction points?
@Christophe I have no idea how exactly black would continue after S14, but to me it looks like he can find some compromise/exchange. Not sure. Requires a lot of reading obviously, which I wanted to avoid doing too much of in this post (I was trying to keep it somewhat generic so the ideas apply to different boards, too). Let's just hope S14 does not completely destroy black :)

Nice spotting the 3+5 shape, it reduces quite a lot and has good yose properties. Also surprisingly safe.

comment How do I chose invasion or reduction points?
@Christophe Thank you. Good points, and upon reading the variations again, I agree white 2 is a strong move there even if it's a bit risky. I've edited the question to take that into account. (The diagram your comment referred to is the fifth of "Hybrid approach".)

Maybe we should shape this question more towards "How do I chose invasion or reduction points?", as that would be easier to search for by others and also reflect the core problem better.
