With just two rounds to come, Anand slipped to the fourth on nine points, a half point ahead of Aronian. Pons remains at the bottom of the tables on seven points.
Anand employed the Queen's Indian defense to counter Ivanchuk's queen pawn opening. The Ukrainian managed to get some complications on board in the middle game but after the center was opened Anand exchanged pieces at will to reach a level knights and pawns endgame.
In the end, both the players had two passed pawns and making progress was not possible. The game was drawn in 58 moves.
Carlsen faced the Slav defense against Pons who played black. The Spaniard equalised early in the opening but fell prey to some wily manoeuvres after the queens got traded.
Carlsen won a piece for two pawns and the resulting endgame was child's play.
Nakamura was at his best in the Queen's gambit declined employed by Aronian. The American got a slightly better middle game and squeezed out black's defensive resources to reach a better endgame.
Aronian tried hard to make a match for it but an erroneous plan led to the demise of his minor piece in the endgame and Nakamura wrapped the issue in 79 moves.
