The strongest of all the teams is the Russian Economist SGSEU-1 Saratov squad with an average rating of 2703, their top player being GM Alekseev,E 2725 (currently 19th in the FIDE ranking).

Note that the strict 'sit or lose' rule (now implemented in most official FIDE events) will apply i.e. that if the player is not sitting down at the board at the beginning of the game he or she will lose on default.
The women's section brings together only 11 teams with the strongest being the one from Monte Carlo. Their top player is the Indian Grandmaster Koneru Humpty rated 2595, the world's number 2 female player.
