Biel, ronda 4, todas partidas comentadas!

De nuevo se vio una bonita ronda de partidas, con un Bologan creativo que no debió perder contra Nakamura.

La preparación de Giri dejó mucho que desear y pronto quedó inferior contra un impecable Wang.

Carlsen jugó una especie de Bogo-India pero salió airoso de la apertura. ¿Se le escapó una victoria en la jugada 44? es posible...
