Cho U Won By A Slim Margin

Cho U Kisei definitely doesn't want to step back, at least no t now. He won the fourth game of the 35th Kisei title match and evened the score to 2-2.


Cho U Kisei

The game started with a new (or at least I think so) variation of the recent Japan's joseki at the lower right corner. At the end of day 1, Iyama created strong walls toward the center while Cho had a solid territory at the right side. Iyama did the sealing move for move 82.


Iyama handled the sealed move.

Iyama played F2, his sealed mov, and opened day 2 of the fourth game. Cho invaded the left side at move 85 and a ko fight started. Cho won the ko and connected his group to his lower left, however he was only able to save half of his group as Iyama captured 10 stones from the fight.


Iyama Yuta Meijin

Cho played the vital point at move 165, the game became really close and finally Cho won the game by 0.5 point.

The fifth game will be played at February 24-25.

Here is the game record:
Cho U (black) vs. Iyama Yuta (white). Result: B+0.5
