The difference between the 'youngest and strongest' Sergei Karjakin rated 2739 and the 'oldest and weakest' Ivan Sokolov on 2654 is relatively little compared to most closed tournaments. This should lead to a tight tournament where the eventual winner will be hard to predict in advance.
A couple of curious statistics: Jobava is 26-years-old and 26th in the world, whereas Vitiugov is 32nd at the age of 23!
All the players are in the World's top 100.
