I wanted to propose something similar to Nonshing cup (see link) between slovak and czech player on littlegolem...
I proposed to play all board - 9x9 13x13 and 19x19 for quicker results...
I asked if there are any interesting. :-)
I like that Tore saw it intersting! :-))) But problem is that Nonshing cup system dont work for more than 3 groups I am afraid... So probably Norwegia, Slovakia Czechia? :-)
