"It is always advantageous to exchange your king's bishop pawn for the king's pawn, since this leads to the seizure of the centre and, in addition, to the opening of a file for the rook."

After four rounds, only two players are perfect in the #DubaiOpen: GM Aleksandar Indjic (2620) from Serbia and India's IM Kaumandur Raghunandan(2352), who has beaten 3 grandmasters including Egypt's No2 Ahmed Adly (2611).
Despite three decisive results in round 5, Carlsen maintains his sole lead in #ShamkirChess with 3.5/5 points. Anand and Karjakin follow him close behind with 3.
