ease with which he can sacrifice the exchange, for the most varied purposes,
be them of defensive or aggressive nature. He did that quite frequently in San
Luis and none less than twice in his previous game against Aronian in Wijk aan
Zee earlier this year. In this game we shall see the players changing parts:
it will be Aronian who will give up both his rooks for Topalov's minor pieces.
Besides the natural desire to take a bit of revenge on this territory, this
might look like a tribute payed to the greatest expert of exchange sacrifice
from chess history, Tigran Vartanovich Petrosian, who was Armenian, too.
Aronian's decision in the diagrammed position must have been dictated by the
unwillingness of leaving Black with a strong knight on c5, but is not likely
to offer an objective advantage.} 23. Qxc5 Rfa8 24. Ne5 (24. Bxb7 {would have

would have weakened the back rank in a decisive way. Aronian will have to wait
for 10 more moves until he will be given an opportunity to trade his rook for
Black's remaining minor piece. Otherwise, Black is much better now. White's
king is relatively unsafe, while his pieces lack stability. The extra-pawn is
more or less doomed, but the time spent by White on eliminating itwill allow
Black start a dangerous attack.} Ba4 28. Rd4 Be8 29. g3 ({White needs to keep

forced to abandon the seventh rank, in order to maintain the g2-square under

g5 next. Lowering of concentration in practically won positions tend to occur
from times to times in Topalov's practice, especially when the opponent puts
up resistance in slightly irrational positions. Two recent examples are
Topalov-Leko Linares 2005 and Topalov-Anand San Luis 2005. The main difference
is that in the previous games he never got into danger of losing, which cannot
be said about the present game.}) 36. Rg4 Bg6 37. Rxg6 $1 {The score stands

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 {Having struggled a little with both the
Grunfeld and the QGA, Kasparov switched to the Nimzo and showed it a greater
tolerance! His loss in Game 10 led most to expect a change, but there is a
rich variety of possible black defences in the Rubinstein.} 4. e3 O-O 5. Bd3 d5
6. Nf3 c5 7. O-O dxc4 8. Bxc4 Nbd7 {A deviation from Game 10, where the
position in the centre was immediately clarified. Stylistically, not to
mention 'politically' it seemed strange to see Kasparov playing like Karpov,
who was for many years the specialist in that particular IQP version!} 9. a3 {
By far the most forcing, and I am surprised to find, clearly the second most
popular choice behind 9 Qe2. The idea of course is that at this stage, black
cannot happily take on c3, since any subsequent capture on d4 will be
re-captured with the c-pawn, when white has a strong centre with no weaknesses.
Since the game follows a very critical course, the assessment of 9 a3 will be
seriously influenced by the ultimate consensus concerning Kramnik's
compensation after move 12.} ({The main line} 9. Qe2 {used to be likely to
introduce one of the sharpest and most tactical skirmishes within the entire

Right in principle - any other move fully vindicates 12 Be2. Right in terms of
the match situation - Kasparov was trailing by two points and having
difficulty making a real impact with white. Also, to my mind unrefuted by any
of the subsequent analysis, for all that white's compensation makes a pleasing
visual impression. In any case, White would like to play c4 next, and the
other move  tried in the position enabled him to do this without inconvenience.

white's position looks really imposing, and noted that Kasparov himself said
he would have enjoyed a crack at the white pieces! True, one might have
expected to find the players on opposite sides of such a principled battle
between all-out attack on the king, and  defence/conversion of the material.
Still, while it can hardly be denied that white has compensation, I am a
little surprised by the general acclaim for white's chances. I regard myself
as a keen, even on occasions incautious investor of material, but I am not
sure how enthusiatically I would adopt the white cause - in principal white's
superiority on the dark squares ( black's absence of dark-squared bishop ) is
relatively easily blunted by the move ...f6 ( + possibly ...e5 ). This of
course creates white square hazards in turn, but black is not so far away from
moves such as ...Ne7, and Bd7-e8 which would serve to cover these in turn. I
do not want to overstate the case - I strongly suspect that white is not worse
- but I believe that Kasparov's play has been 'correct per se', rather than
just ' correct for the occasion'.} Nc5 {Again looks the right decision.} (18...
