I recently finished this new go design that incorporates a fascinating 9x9 endgame problem.
This swordfish is the 13th drawing in my series of go artwork that features animals, paper marbling and of course the game of go itself. I sell these works as postcards and posters in various sizes.
I came across this endgame problem on the Facebook page of BIBA - Blackie's International Baduk Academy - a go school (go is called baduk in Korea) in Seoul. BIBA is specifically aimed at Westerners who want to study the game. The head masters of the school, Diana Koszegi and Seungjun Kim, kindly gave me permission to use their go problem in my art.
The endgame problem is interesting for two reasons. At first glance, the position seems to be taken from a real match that was played on a 9x9 board, but on closer inspection it turns out that there are 21 stones for black and 23 for white. It is black to play and no stones have been captured. In these circumstances, in a real match both black and white would have the same amount of stones on the board. So we can conclude that this is a constructed problem. The second reason is the solution. Tip: think outside the box.
Do you want to know the solution? Have a try in the game editor below. I have included several diagrams so it is not apparent on first glance which of these is the solution. Enjoy.
