Carlsen Shirov OF Aerosvit 2008

Before the coup of 61 fatal black Shirov:

We shot at 61 per Shirov and there he commits error fatal: he places his crazy G7 ( red arrow).
In doing so he abandons control of the diagonal ( brown arrow). But this control
was essential to prevent the king from Carlsen to advance into the green box ( pink arrow). Indeed
for the King of Carsen put themselves in this box means closing all exit door to the King of Shirov on the column and thus H seal it in a network of Mat.

As long as the king of Shirov could escape to the South on his column, Shirov still retained a hope to draw.

The only solution keep control of the diagonal for Shirov was to go north west and to place his bishop on c7 b8 or ( yellow arrow ) (not on the rectangle red controlled by opposing the tower).

pity: until end Carlsen Shirov has resisted and suddenly everything collapses!
