becoming more and more popular, even at a top level. White is playing the Slav
defense with an extra tempo.} Nc6 6. Nbd2 Bd6 7. Bg3 O-O 8. Bd3 b6 9. Ne5 {
This is one of the main ideas of the whole line. White wants to attack on the
kingside and therefore plays in a Stonewall way.} Bb7 10. f4 {The bishop on g3
is also seemingly well placed, ready to go to h4. It seems as White had won
some tempos on the development of that piece, but if we count carefully, we
shall see that it is all the same. In the Stonewall the bishop goes to h4 via
d2-e1-h4. Here Karjakin had lost the time while maneuvering Bf4-g3-h4.} Ne7 {
A nice defensive maneuver.} 11. Qf3 ({Funnily, Karjakin has some experience
