The annual Sokov's Tournaments starts on December 8, 2006.
This is the only information I have - no links, no details are available at this time.
Last couple years some players expressed the desire to visit St. Petersburg to participate in this wonderful checkers tournament that normally boasts hundreds of players from many countries competing for the bragging rights in several divisions, from Top Master to Gold Bar levels.
Having good time, enjoy checkers, make new friends, and absorb the culture of one of the most beautiful cities in Europe - what else one could wish for?
Just in case - start on your passport if you ever want to travel abroad.
