I was stumbled upon the
Lee Chang Ho Facebook fanpage (it has not been updated recently), and found this game between Lee Chang Ho and Lee Sedol that is from the Myeongin League according to the page. This end game resignation surprised me because originally it appeared that black was connected. After pondering for awhile, I finally arrived on the answer. Enjoy solving this!

Question: At the end of the game, if If white cuts, how does black stay connected?
