Leko-Kramnik, Mamedyarov-Anand, Naiditsch-Alekseev, Carlsen-Gelfand

All 4 games were drawn today, so no changes in the standings. The current standings after round 5:

1 = Kramnik(3.5)

2-3 = Anand, Alekseev(3)

4-5 = Mamedyarov, Leko(2.5)

6-7 = Gelfand, Carlsen(2)

8 = Naiditsch(1.5) 

There were two interesting notes about the openings. Anand decides to play 5...b5 in the Queen's Indian a rare sideline in his game. For another interesting game with this move you can search for "Markus(2567) - Postny(2622), Dresden Germany, 2007". The other surprise was seeing Kramnik using the Petrov defense against e4. Lately Kramnik has been playing the Ruy Lopez but now we finally see a Petrov defense. Will this bring the Petrov back into popularity at the highest levels again?

Here are the 4 games from today:
