8/31/2018 – Halftime and a rest day at the Russian Championships, after six of eleven rounds. In the open tournament, six players are in the lead each with 3½ out of 6 points, but the Elo favourites are not among them. Even in the women's tournament, the nominal favorites have had a hard time. Olga Girya and Alina Kashlinskaya lead with 4 out of 6, while Alexandra Kosteniuk (pictured) has scored just 3 out of 6 or fifty percent.
