After losing the first game to challenger Iyama Yuta, Kisei title holder Cho U won the second game.
I found Iyama’s move 40 quite amazing, it is played in a place that would never occur to me, see the next diagram.
In the game black replied by connecting with the triangle marked stone. This makes move 40 a very efficient forcing move, since now white has even more forcing moves from the outside. This diagram shows the strongest continuation for white – in fact white did play this, but much later in the game.
The last diagram shows why black cannot reply aggressively in response to white 40.
Here is the complete game.

If you hadn’t shown the variation after move 40, I’d shout “misclick” at the monitor or blame the scribe. A clear typo, or 30k move.
Thanks for sharing
I`m glad that you are writing on this blog again, thank you!
After you did not wrote something for a long time, i thought you never would again…
I like it verry much that you make comments on the games instead of just presenting the game records … please go on with that , i (and i think a lot of other GO fans) would appreciate that very much. Greetings from germany, amon
