Weakening Black's control of the open c-file.

A sad necessity, but only thus can Black defend the a7-pawn.

After improving his bishop White secures it, and the pawn as well.

White has gained a pawn and there is a second one coming up on f7. He soon won the game.

Preparing to triple the major pieces on the c-file.

The natural 2...Rbc8? fails to 3.Nxb7! Rxc3 4.bxc3+-

A good exchange to facilitate an attack on the b7-pawn.

This leads to material losses;
Black should have tried 5...Ng4 , challenging the strong knight on e5.

With the inevitable threat of 11 Rcc8. White soon won.

Disputing the open file.
