Una duramente luchada primera ronda sólo tuvo un resultado decantado. La partida entre Adams y Navara fue la última en terminar y solo cerca del final el checo buscó las tablas.
Adams, Michael 1-0 Navara, David
Adams jugó una estupenda partida y obtuvo un final ganador con alfiles de colores opuestos y damas, pero le faltó precisión en un momento clave.
Primera ronda, primer líder: Mickey Adams

Primera derrota tras una larga lucha: Navara
Wojtaszek, Radoslaw ½-½ Rapport, Richard
Lo ínico predecible sobre las aperturas de Rapport es que son completamente impredecibles. Hoy escogió la defensa Chigorin, lo que no es una opción muy común en las partidas de grandes maestros. Wojtaszek, no es ninguna sorpresa, consiguió una posición avasalladora ddesde la apertura, pero dejó escapar a su rival.
El ajedrez de Rapport es tan raro como siempre

Wojtaszek sin duda dejó pasar su oportunidad en esta jornada
Vachier-Lagrave, Maxime ½-½ Eljanov, Pavel
Una Berlinesa interesante en la que ambos jugadores trataron de restringir los avances de peón de su rival. Eljanov ganó un peón, pero no logró ventaja: las piezas de MVL estaban bien colocadas y las tablas parecían probables. el ucraniano incluso apuró más de la cuenta, pero siempre fueron tablas.
