27/07/2012 – El vencedor del día en la cuarta ronda de ayer en Biel sin duda fue el chino Wang Hao. Tras su victoria sobre Nakamura en la tercera ronda, se impuso al hasta entonces líder Anish Giri. Con negras, en una Defensa India de Rey, aceptó la invitación de Giri para repetir la variante que el día anterior había dado la victoria al holandés contra Bacrot. Jugó la Variante Sämisch y se metió en apuros directamente después de la apertura, lo que primero le costó material y más adelante la partida. Nakamura ganó una partida larga y dramática contra Bologan, el sustituto de Morozevich. Ambos tuvieron opciones, pero cuando el tiempo se estaba agotando, Bologan se enrededó en la telaraña de mates de Nakamura. Bacrot y Carlsen firmaron tablas. Ronda 4...

The Nimzo-Indian has stood the test of time for over a century: Still a top choice for elite players today, from Magnus Carlsen to Praggnanandhaa, it remains one of Black's most reliable ways to fight for real chances against 1.d4 2.c4 3.Nc3.
1.c4 e5 2.Nc3 Bb4!? is an opening idea well worth considering. Black immediately threatens to double the pawns on c3 in the style of the Trompowski or Sicilian Grand Prix attack.
