queenside and the tempi spent on advancing the a-pawn will be retrieved
thanks to the relatively unsafe situation of the bishop. At the same time,
Black is deprived of the freeing move …Na5 forever. On the other hand,
Black no longer has worries on the queenside and he can even hope that at
some point the a5-pawn will become weak. } 10… Ba7 ( { Accepting the

operation has ended in a fiasco. Instead of opening the queenside, he has
been left with a potentially bad bishop, while Black has a fantastic
blockade on the dark squares. This means that the result of the opening
(let us say, after 21 moves) has been anything but satisfactory for White.

{ White has more or less completed his useful moves, but in the long run
risks being crushed by Black’s kingside majority, while on the queenside
there is nothing going for him. } 27… Nh7 $6 { Anand confessed that when
he saw this move he briefly considered resigning. Indeed, Black’s plan is
rather intimidating: he will simply set his kingside majority in motion.
And yet, the text move is premature. The fact is that Black’s queenside
situation is not 100% safe. The b4-pawn cannot be defended by its colleague
(we can see one of the positive sides of a4-a5) and will need the support
of a more important piece, the queen’s rook probably. Also, if White
manages to exchange the c5-knight without allowing the other black knight
to replace it, the c5-square will have to be secured by the second rook.
Obviously, this will reduce Black’s attacking potential and somewhat spoil
his coordination. Playing …Nfd7 does not look too appealing, because it
would practically cut Black’s position in two parts without comunication,
leaving the king exposed. However, other useful moves are available, before
declaring war on the kingside. } ( { One natural continuation is } 27…

28. Ne4 $1 { Suddenly, White gets back into game. } 28… f5 $6 { Black
seems to be hypnotised by the a5-pawn. By accepting that his rook is
decoyed to c5, he will somewhat spoil his coordination. After the text
move, all three results become possible, for the first time since the
opening. } (28… Nxe4 { would have been safer. } 29. Bxe4 Nf6 30. Nc2 (30.
