The 5th round of the Istanbul Chess Olympiad saw the heavyweights crossing the swords on the top two tables.
The 2011 World Champion Armenia was paired against the defending Olympiad Champion Ukraine. Levon Aronian was very energetic with white pieces and already my move 30 he won an exchange from Vassily Ivanchuk. The Armenian continued posing problems to his opponent who eventually resigned when a loss of the piece became imminent.

Russia and Hungary played on the 2nd table. Leko and Kramnik performed one of their trademarked draws, while Judit Polgar and Karjakin continued the theoretical discussion in the Ruy Lopez Berlin.
