Indian Grandmaster Koneru Humpy recovered from a difficult position to play out a draw with defending champion Yifan Hou of China in the fourth game of the World Women's Chess Championship at Tirana , Albania on Friday. It was a decent comeback by Humpy after losing the third game with white pieces. With the draw, the third of the contest, Yifan maintained her slender lead of Two and a half points against Humpy's one and a half points. Six games still remain in the Ten-game contest. The fifth game of the Two Lakh Euros championship will be played after the second rest day with Humpy playing black again. This is to ensure that one player does not get advantage of playing a white game after every rest day.
