Hi! After some analyses have confirmed that with Super Taraguchi-10 it is too easy to force a sure draw after 5 moves, the referee team has decided to lose the 10 move limitation. Also, the 5th move can be placed anywhere on the board. This rule will be used instead of the Super Taraguchi-10 for the Correspondence World Championship.

Hello everyone! As you may already know, starting from this year, the CWC rule will be changed to Super Taraguchi-10. To familiarize players with this rule, Renju Caffe has started regular Super Taraguchi-10 tournaments. Everyone is welcome to participate:
