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.

This doesn't help White, but it was difficult for him to find a constructive move.
