Traditionally,
the title of world champion is decided by a mano a mano battle
between the world’s two top players. This format was recognised even
in the early matches between Staunton and St Amant, and
Morphy and Anderssen, which predate the widely accepted year (1886) from
which the Championship officially emanates.
The sole exception to this rule hitherto was 1948 when Alekhine’s death as
incumbent caused an interregnum which necessitated a five-man match
tournament to decide the destination of the title. The Soviet iron-man
Mikhail Botvinnik won easily, ahead of Vassily Smyslov, Paul Keres, Sammy
Reshevsky and in last place the former world champion Dr Max Euwe.
Botvinnik raced away with the tournament making a clear plus score against
all his rivals. He considered the following to be his best game:

At first sight
Black has nothing to complain of: he has easy development and a pawn
majority in the centre. But the safety of his king becomes a
constant headache.
14 ... Nc5
It is
understandable that Black should want to exchange the dangerous
d3-bishop as soon as possible, but in so doing he loses control of the
important central squares. It is noteworthy that in this case
simplification does not solve all Black’s problems – while the queens
are on the board, his king remains in danger.

Foreseeing the
inevitable exchange of his g7-bishop, Euwe apparently thought it
dangerous to castle, but with his king in the centre he will have even
greater problems.
17 Rc1 Rd5 18
Be5
It transpires
that the strange manoeuvre ... Rd8-d5 has merely played into White’s
hands: he carries out his plan with gain of tempo, and the exchange of
one pair of rooks does not weaken the attack.

The attack on g2
is illusory: 21 ... Rg8 22 Qxh7 Rxg2+
23 Kf1, and Black can resign. By driving away the knight, Black is
hoping to breath more freely. But this is a mirage.
22 Qg3
White does not
begrudge the knight: the invasion of his two heavy pieces on the
seventh rank is fatal for Black.

I have based these
notes on Kasparov's from his Great Predecessor series.
At
this very moment eight grandmasters have assembled in Mexico City
[Editor: Due
to production delays, this article is first appearing after the conclusion
of the tournament, though at the time it was written the event was still in
full swing.]
where they will once again decide the undisputed World Championship by means
of a tournament. This circumstance reflects the resolution of the
schism that was obtained in the chess world in 1993 and also the confusion
surrounding Kasparov’s retirement from world chess. The players are:
world champion Vladimir Kramnik, Viswanathan Anand Peter Svidler, Alexander
Morozevich, Peter Leko, Alexander Grischuk, Lev Aronian and Boris Gelfand.
Next year FIDE claims that the Championship will revert to its traditional
match format.
 In round two of the undisputed World
Championship tournament in Mexico City, reigning world champion
Vladimir Kramnik played what has so far been the most controversial game of
the tournament. He devised a gambit which looks very much like a queenside
version of the venerable King’s Gambit or even the Evans, both of which tend
to throw their weight, for the sake of a pawn, in the direction of the black
king.
After this astonishing opening Kramnik went on to win a game where the
material balance at any given moment might best be described as irrational.

Safer is 5 Qa4+, regaining the pawn
at once.
5 ... a6
Black announces his intention of clinging to his
booty on c4.
6 Ne5 Bb4+ 7 Nc3 Nd5 8 0-0
       
       
       
       
       
       
       
       
Entering terra incognita. The
standard move here is 8 Bd2.
8 ... 0-0
Cowed by the possibility of
stumbling into Kramnik’s preparation, Morozevich avoids the main test of
White’s idea. This consists of 8...Nxc3 9 bxc3 Bxc3 10 Rb1 Qxd4 11 Qa4+ b5
12 Qc2 Qxe5 13 Bf4 Qf6 14 Bxa8 Ba5. In this position Black has three pawns
for the exchange and must stand better.
An alternative idea for White is to
try 8 ... Nxc3 9 bxc3 Bxc3 10.Ba3 when 10 ... Bxa1 11 Qxa1 grants White
nebulous tactical chances. However, the simple 10 ... Qxd4 11 Qxd4 Bxd4
snuffs out White’s chances.
9 Qc2 b5 10 Nxd5 exd5 11 b3 c6 12 e4 f6
       
       
       
       
       
       
       
       
13 exd5
By now White is committed to this hazardous
continuation.
13 ... fxe5
If 13 ... cxd5 then 14 bxc4 bxc4 15 Nxc4
and White emerges unscathed from the complications.

A natural enough move since Black is determined to neutralise
possible White tactical trickery along the a2-g8 diagonal against the black
king.
An alternative way of achieving this goal is by 15 ... Bc3 16 cxb5 Kh8
17 Ba3 Bf5 with complications.
It should be noted that Black has to be very
careful about allowing White to play the move c7 which opens up a battery
against the black rook on a8. This resource often constitutes White’s only
saving grace.
16 cxb5 d3
Possibly superior is 16 ... Ra7.
