Black has managed to create a perfect structure against the doubled c-pawns. How do we keep putting pressure on the position?

Now the black knight and bishop put pressure against c4 and this forces the white bishop and queen to protect it.

Intending to eliminate one of the defenders of c4.

The only move that parries Be4 and Bxh7+.

Another piece comes to attack the c4 weakness!

In this balanced position, one of the best players of the world from the last century and even an analyst of the ex-world champion Robert James Fischer came up with a very interesting strategic idea: trade the fianchettoed bishop for the centralized knight on e5.

14...Nxe5 is also very playable and natural.

Larsen is right to consider that doubling the pawns on the e-file is fine since the white dark-squared bishop will not be strong and Black will have nice control over the center and the open f-file.

The only good square for the rook, supporting the d4-pawn.

And we need to be fast now since White is now threatening to play Qg4 once the e5-pawn is protected by the rook.

White tries to protect the e5-pawn, but now we can clearly see how the black knight is superior to the white bishop.
