From the Wikipedia article on Yunzi stones Like glass Go stones, yunzi are very durable. However, like glass stones, yunzi are still at risk for chipping if they are dropped or otherwise come into sharp contact with hard surfaces such as metal, tile, or stone. The problem you describe is more a property of your (very hard) tile floor. I would suggest ...

I believe your information comes from this unofficial rating system: http://www.goratings.org/ Fan Hui's page on that site: http://www.goratings.org/players/1480.html Fan Hui only only played a few pro games - none recently - so his ranking there (or any other pro ranking system) is unreliable. 1P-9P rankings are not ratings (you only go up) and don't ...

Just to add a few notes in addition to Pieter's answer, and with a hint to your implied question (can AlphaGo beat Lee Sedol?): First off, I'm not sure if you thought being 9p automatically means being stronger than 2p. This is not the case. However, in this particular instance, other matters are of more importance. Fan Hui has not been competing in Asian ...

Is there any official and accessible world ranking ? No; Rankings are done by national Go organizations, with some variance existing between them. What is the exact rank of Fan Hui ? As reported here, Fan [Hui] earned a 2-dan professional ranking in China before emigrating to France, so it appears that go software has reached the level of ...

There is no way to know your opponent's strength based on the information you posted. KGS adds the question mark to alert you about an unreliable rating, because that account has played too few games. Another clue is the graph itself. Important variations like this are typical of accounts with few games. Maybe that person only played one game in February ...

A Japanese pro 9-dan, Tomoyasu MIMURA (born 1969) writes in his blog entry (3 Feb 2014), ''I had never seen, or heard of 9x9 board in my childhood'' and ''In 1987 started the TV show 'Mini-Go One Game Match (ミニ碁一番勝負)'.... Professionals had begun to pay attention to the unexpected depth of 9x9 board game some time before''. Therefore, around 1985 would be a ...

You didn't lose the corner, you exchanged it for a position on the right side. That's how pincers work, so nothing wrong here. The high pincer combined with your move at 11 looks right here as it prevents a white moyo. The sequence might not be optimal (see josekipedia/eidogo for the many variations), but the end result looks ok. Capturing at 13 is quite ...

1 and 2 are "honte" moves. They result in solid positions as they remove all aji from the marked stones, but are not mandatory. $$cm1 $$ +---------------------------------------+ $$ | . . . . . . . . . . . . . . . . . . . | $$ | .

First off, count the current score. If you're winning, do not invade. Just make sure you keep white small enough that you still win. Let use further presume that black would be losing. You counted, so you know by how many points. A move around c could be parried with a sacrifice of two white stones while sealing off the rest of the upper right corner ...

Many question in one post ... An invasion on a should work, because the corner is not yet 100% secure. White will probably build up strength to the outside leaving no potential on b. White will probably get the initiative afterwards. An invasion on c looks very big, probably bigger than the corner invasion because of the two white stones to be captured. ...
