Quadruple Ko
There was a recent quadruple ko between Kono Rin Tengen and Akiyama Jiro 8 dan. Here is the final position (image source here):

As always in such positions when no side can afford to give up the ko fight, the game resulted in a draw.

Yesterday, it happened in a game i was playing that 2 double kou appeared for the life and death of 2 groups. Unfortunately my oponent could afford to throw away 1 group and win the game by 6.5 points. Zannen! ^^

Couldn’t find this game record. The source article tells that the game was played on 2008-06-28…
After some research on go4go or gobase, there is only one game between those 2 players on 2007-07-19… but the game record doesn’t match at all this position !
Any idea where to find the game record ?

The Agon Kiriyama Cup game on 2007-07-19 is very probably a rematch for this no-result game. Have to check the Nihon Ki-in yearbook 2008 whether the quadruple go game record is available at all.

Hi Gwen,
On the one hand, Vesa is right: there was a rematch, so a different game between the same players at a date close to the original may be that one.
On the other hand: there are a lot more official games than that ones available at go4go or gobase, especially in the lower qualification stages.
