Ke Jie is the strongest go player. Sedol is the 5th strongest.<p><a href="http:&#x2F;&#x2F;www.goratings.org" rel="nofollow">http:&#x2F;&#x2F;www.goratings.org</a><p>The difference is 100 Elo, which is substantial.<p>Edit: Ke Jie has 700 Elo on Fan Hui. About the same as the gap between Magnus Carlsen and the strongest player at my local chess club.
