[9][10] Wagner started the series as by far the lowest ranked player, almost 100 Elo below her next nearest competitor, and more than 200 behind the highest-rated, Aleksandra Goryachkina.

Her play generally in Astana was marked by time trouble, but she recovered with a series of draws, and two wins versus Kosteniuk and Kashlinskaya (this last, her favorite game at the tournament).

[12] There were late tournament losses to Kateryna Lagno and Tan Zhongyi, but a last round win over Shuvalova secured her a first International Master norm and a share of 6th (of 12).

[14] In the final leg of the Women's Grand Prix in Nicosia, Wagner finished in clear first with 7/11, including victories over Goryachkina and Lagno.
