The highlight of April 2014 was the Vugar Gashimov Memorial held in Shamkir, Azerbaijan. It was won by the World Champion Magnus Carlsen, who despite losing two games, scored 6.5/10. Caruana was second with 5.5 points.
The other major tournaments this month were the Women's Rapid and Blitz World Championships held in Khanty-Mansiysk, which were won by Kateryna Lagno and Anna Muzychuk respectively. Earlier that month Khanty-Mansiysk also hosted the Women's FIDE Grand Prix tournament, won by Hou Yifan, so April was truly a month of Women's chess in that city.
