I have been the president of Finnish Go Association and no longer maintain a club list and a calendar. Here are some old tournamet results which are not in the calendar.

More on Go in Finland at Finnish Wiki.


I am the chairman of the rules and ratings commission of the European Go federation.

I have created various interesting positions considering the different rulesets of GO. Here is a diagram of position which illustrates the principal difference of Japanese and Chinese rules. What is the status?

This is diagram 2, Where using Japanese Nihon Ki-in 1989 rules might produce an unexpected result. What is the status? Does one need to capture?

This is diagram 3, It was shown to me by T. Mark Hall. Consider Ing rules. Is it a fighting ko or a balanced ko?

Diagram 4 shows Ing's triple hot stones. I created the first version 1983 and Mr. Ing had to extend his list of hot stones and double hot stones with triple hot stones. Later I created a position with quadruple hot (or ok) stones.

Diagram 5 introduces a tesuji filling your own eye by Ing rules.

I will add more diagrams and problems when I have time. Some positions on Harry Fearnleys go pages. Robert Jasiek has written pages about ko-rules.

Some of the positions in a more nice format edited by Fred Hansen.
