A steady day with no decisive results doesn't mean that the players weren't seeking the full point.
Nakamura maintained an edge after the opening against Ivanchuk's sideline in the Nimzo-indian. He was even able to win a pawn, but Black was too active and he never looked like making any progress.
The same could be said for Carlsen (who won a pawn) against Karjakin (who was sufficient active to be in any danger).
Nisipeanu played cautiously against Radjabov's Schliemann defence and Black equalized comfortably. Opposite bishops led to the players abandoning any hopes of winning.
At club level the Schliemann (or Jänisch) Defence is an aggressive weapon, but at this level it is used quite successfully by Radjabov and others to nullify White's opening advantage.
