诸宸 (Zhū Chén) & Yasser Seirawan – 侯逸凡 (Hóu Yìfán) & Nigel D. Short
成都 (Chéngdū), July 8, 2014
Nimzo-Indian Defence E34

As observes Mark Crowther (The Week in Chess, July 9, 2014): “Nigel Short and Hóu Yìfán were favourites to win after being paired together but as Short said afterwards: ‘Basically we blew it yesterday with a collective collapse of concentration against Yasser Seirawan and Zhū Chén, turning a clearly better position into a dead lost one in the space of about two minutes (and half a dozen moves)’. They finished 3rd behind the teams of Zhū Chén/Yasser Seirawan and Xǔ Yùhua/Yú Shǎoténg both finishing on 4/5”.
