Tsumego Answer

This is the answer for Refreshing Tsumego.

L19 looks natural here, but it doesn't work due to cut at Q18.


Other answer like G19 doesn't work as well.


Here M19 is the correct answer.

Refreshing Tsumego

I haven't got the chance to post as usual due to my assignments and tests. It's 11 pm and I'm still working at my Data Mining, but it's always fun to do little tsumego during such time (well, kinda finding a reason to slack off :D)

Black just played at A because he thinks that his "B" group has alive. It's white to move and kill black. Enjoy :)

Rin Kanketsu's First League

Rin Kanketsu (7 dan) must be very happy the day he beat O Meien at the final of the last preliminary at the 36th Meijin Championship.



This will be the first league for Rin Kanketsu. I think this is pretty good for him, considering that he is relatively young (he is 26 now). Good Luck for Rin Kanketsu.


Rin Kanketsu

Also notable, this is Yamashita's return to the league since he was demoted at 2006. Hane Naoki also make a comeback to the league. The last time he was in the league was in 2001 when he held Tengen title.

Here are the players who will play at the 2011 Meijin League:
1. Takao Shinji
2. Cho U
3. Yuki Satoshi
4. Sakai Hideuki
