Women's World Championship: Game 4
After taking the lead in game three of the 2011 Women's World Chess Championship, defending champion Hou Yifan had white in the fourth match game today.
Humpy Koneru varied from her choice of the Petroff in game 2, this time playing an Open Ruy Lopez and despite conceding a pawn in the ending the game finished as a draw.
Tomorrow is a rest day, and then the order of colours alternates, so that Humpy will have black again in game five on Sunday 20 November.
