FYI, pool is a massive sport in Russia, besides their own game called russian pyramid. The truth is that all pool rooms are owned by mafia. There are rooms with over 100 tables in Moscow and St. Petersburg and many friends of mine have visited there in big tournaments and I've been told all foreign guests are being treated like kings there.
Have to add that pool is played in major cities, I doubt smaller ones (poorer ones) don't have decent pool rooms at all...
