positional struggle with mobile pawn chains and all pieces on the board. In
the '60s, the Closed Sicilian used to be a deadly weapon in Spassky's hands.

7. Nh3 {This way of developing the knight was also one of Spassky's favourites.
I must confess that when following Carlsen's play I have every time the
temptation to compare him with another World Champion from the past: now
Fischer, later Lasker, but today we surely have Boris Vassilievich in the
background. On more concrete terms, what could be the great idea behind the
last move? Shouldn't the knight (after f2-f4) go to f3, controlling the
important central d4- and e5-squares? Actually, it would be of little use to
put pressure on such well defended squares, so it is a good idea to be heading
for the only weakness in Black's setup, the d5-square. After the planned f2-f4,
the prospect of a knight jump to f4-d5 somwehat restricts Black's options.} ({
