{Along with some advantages which doubled pawns bring to their possesor there
are certain disadvantages as well. One of the chief drawbacks is the inability
to create a passed pawn on the flank where he has such pawns, while his
opponent might have a healty pawn majority on the opposite wing. Here are some
examples of this theme:} 1. d4 Nf6 2. c4 e6 3. g3 d5 4. Nf3 dxc4 5. Bg2 c5 6.

gives White a space advantage and some play on the d-file; in the middlegame

{The match had a promising start: 75 moves of uncompromising battle, abrupt
changes in the course of the game and... a decisive result. It could have all
ended in an "interesting draw" right after the first time control if Black had
been any other player than Topalov. For Kramnik, the general pattern must be
quite familiar. Two years ago in Brissago, he also won the first game of his
match with Leko after his opponent overstepped the limit of admissible risk.}

is in slight contradiction with the general rules of development: White moves
for the second time in a row with an already developed piece. Even more
paradoxical is the justification of such a decision: White intends to
effectuate a new series of 3 consecutive moves with the queen in order to win
the pawn back! In fact, moving around with the queen before the development of
the other pieces has been completed is quite typical for the Catalan, the most
recent example in Kramnik's practice being his game against Naiditsch from
Dortmund 2006. The explanation why such radical deviations from the normal
course of the game are viable is probably connected with what I would call
"The quality of development". Indeed, the Catalan bishop is sometimes so
strong that it can compensate for a delay in the mobilization of the other
forces.} ({The more natural} 8. Nbxd2 {allows Black maintain his extra pawn

been exchanged. White has a nice pawn structure and, after the next move,
strong pressure along the h1-a8 diagonal. However, Black's a-pawn should not
be underestimated. In order to block it or simply capture it, White will need
to concentrate a considerable amount of resources on the queenside, leaving
the other wing slightly weakened. Compared with the final position of the
variation given in the notes to White's 13th move, the relation between the
black bishop and the white queen's knight is reversed. Here, the bishop is
dominating the knight.} 18. Ne5 Ra7 19. Bf3 Nbd7 20. Nec4 {One important

correct play Topalov's decision was entirely viable.} 27. Bxf3 gxf3 {For the

The adherents of the Catalan Opening like very much to place knights on the
c6-square, especially if they cannot be driven away easily. In this concrete
case, however, it is not clear yet whether this yields White any concrete

Bb4+, one of Black's main continuations.} 7. Qxc4 Nb6 8. Qb5 $5 {A slightly
mysterious move that became popular along the past years. What is the queen
supposed to be doing on such an exposed square, in the immediate neighbourhood
of an area that is very well controlled by the black pieces? It is quite
obvious that rather soon White will have to lose additional time with it.
White's whole concept is very concrete. Black's main (if not only) source of
counterplay in case of more natural retreats of the queen is the opening of
the centre by means of ...e5. The temporary presence of the queen on b5 is
aimed to produce minor changes in Black's position, which would make ...e5
less efficient or simply impossible.} ({The older main line went} 8. Qd3 e5 9.
Nxe5 Nb4 10. Qc3 Qxd4 11. O-O Qxc3 12. Nxc3 Bd6 {and White's advantage is of
rather symbolic nature.}) 8... Bd7 {Black puts pressure on the queen by
developing a piece. However, in doing so, he releases the pressure against the
d4-pawn, making the counterplay based on the advance of the e-pawn more
problematic.} ({The main alternative is} 8... a6 9. Qd3 e5 10. Nxe5 Nb4 11. Qc3
Qxd4 {and now White usually tries to take advantage of the fact that the
b6-knight is not defended as a consequence of ...a6 by playing} 12. Qxc7 {
However, the queen is rather exposed there, which allows Black obtain strong
counterplay.} ({In fact,} 12. O-O Qxc3 13. Nxc3 Bd6 14. Nf3 {also deserves
attention, since the presence of the pawn on a6 slightly weakens the whole
black queen side, offering White better chances for an advantage than in the
lines starting with 8.Qd3}) 12... Be6 {We are following the newest game as the
main line of this sub-variation. It eventually led to an advantage for White,
but several deviations are possible for Black.} (12... Be7 13. O-O N6d5 14.

Black gives up the idea of carrying out ...e5 and prepares ...c5 instead,
taking advantage of the fact that he has won a whole tempo for the development
of his queen side.} 10. Qd3 $146 {An interesting novelty. White intends to

from the variation that had led him to defeat in the previous game with Black.

position itself had been ok, it is better to avoid unpleasant memories. One
famous example about what can happen in the contrary case is the Candidates'
match between Spassky and Geller in 1968. The latter stubbornly played the
same line against the Closed Sicilian and lost the first 3 games with Black.

pressure along the d-file (after 0-0 and Rfd1), maintaining the threat of Qg5

advantage of leaving Black with a rather narrow choice, resulting in a

The first optical sensation is that a massive migration of Black's pieces from
the kingside to the opposite wing has taken place. Paradoxically, White will
not try to attack the slightly vulnerable king's position, but will hit

forces. This is enabled by the fact that all the queenside pieces are
undeveloped yet, while the b4-bishop is vulnerable. Der erste optische
Eindruck ist, dass eine massive Wanderung der schwarzen Figuren vom Kцnigs-

die etwas anfдllige Kцnigsstellung anzugreifen, sondern genau auf der Seite

{This game against Anand's second for the match in Bonn was my best one in
Novi Sad, because although I was better, clearly better or even winning in 7
of my 8 games, I was actually only able to convert my advantages on two
occasions. In a certain way, this was symptomatic of the performance of the
whole team, because apart from Daniel Fridman none of the players was in good
form.  Die Partie gegen den Bonner Anand-Sekundanten war meine beste in Novi
Sad, denn obwohl ich in 7 meiner 8 Partien besser, klar besser oder auf Gewinn
stand, konnte ich meine Vorteile nur zweimal tatsдchlich verwerten. In
gewisser Weise war das symptomatisch fьr die ganze Mannschaft, denn auЯer
Daniel Fridman war keiner der Spieler in guter Form.} 1. Nf3 Nf6 2. c4 e6 3. g3

I may not have been anticipating this variation, but the surprise was anything
but unpleasant, because White is able to choose between sacrificing a pawn for
the strategic initiative and aiming for a superior endgame.  Mit dieser
Variante hatte ich zwar nicht gerechnet, aber ich war alles Andere als
unangenehm ьberrascht, da sich WeiЯ aussuchen kann, ob er einen Bauern fьr die

found other supporters since then, I believe that Black has a long struggle
facing him before he reaches a draw. The proud Catalan bishop on g2 disrupts
Black's coordination, so that the a5-pawn tends to become a weakness and White
has nice ourposts for his knights. All das ist seit der 1. Partie des
WM-Matches 2006 zwischen Kramnik und Topalov gut bekannt und obwohl die
schwarze Spielweise weitere Anhдnger gefunden hat, glaube ich, dass Schwarz
ein langer Kampf um das Remis bevorsteht. Der stolze katalanische Lдufer auf

consists of fixing the black pawn chain by e4-e5 and then gaining more and
more space by advancing his other pawns. At the same time, White should only
exchange pawns if by doing so he makes substantial progress. Otherwise, there
is the rule of thumb that the exchange of pawns helps the defender who will
have fewer potential weaknesses to worry about. Der weiЯe Plan besteht darin,
mit e4-e5 die schwarze Bauernkette zu fixieren und dann durch Vorrьcken der
anderen Bauern immer mehr Raum zu gewinnen. Gleichzeitig soll WeiЯ nur Bauern
tauschen, wenn er dadurch substanzielle Fortschritte erzielt. Sonst gilt die

{Both Azerbaijan and India had a great start at the 2016 chess Olympiad. This
crucial fifth round encounter had a great impact on the path of these two
teams toward the end of the tournament: the Indians kept their chances for the
medal until the very last minute and finished 4th, while 'the hosts' did not
manage to find their right momentum ever again after losing this fifth round
match to India. Mamedyarov had a great start up to this point, scoring 4 out
of 4. His flamboyant and aggressive style now had a new test against India's
super-GM Pentala Harikrishna.} 1. d4 d5 2. c4 e6 3. Nc3 Nf6 {Harikrishna
offers the chance of 4.cxd5 to Mamedyarov. Whether he was going to take on d5

Harikrishna: instead of going for a solid opening, Harikrishna offers the
chance of entering the Moscow or Botvinnik System.} 5. g3 $5 {An interesting

While closed games did bring Anand success in Bonn 2008 and Topalov certainly
expected 1.d4, the Catalan until now figured only in a few Anand's blitz games.
Running a bit ahead, it seems a psychologically astute choice - Topalov
usually strives for the initiative from the beginning, while in the Catalan
most of Black's ambitious choices are connected with taking a P and holding on
to it, while trying to survive White's initiative. As we saw in numerous games
earlier (For example in Game 1, or Topalov-Kramnik, Wijk aan Zee 2008 to name
a few), Topalov is more comfortable with sacrificing material himself, than
defending. This game offers further proof.} dxc4 {The most solid moves are} (
4... Be7 {and}) (4... Bb4+ {Topalov most often played the latter move and
turned to it in Game 7, albeit even then he connected it with an attractive
sacrificial concept.}) 5. Bg2 a6 {If MegaBase is complete, Topalov previously
played this only once. Possibly he was counting on the effect of surprise and
in a sense this calculation paid off to certain extent - Anand's play in the
transition from the opening to the middlegame wasn't quite ideal (see move 15).
However, the general character of the resulting positions will still fit him
fine enough.} 6. Ne5 ({A more usual continuation is the pawn sacrifice} 6. O-O

{With two rounds to go I was been in the leading pack with many other players.
Most likely it was my last game with white, so I thought it should be the time
to put some "real" pressure on my opponent. Not a simple task, especially
given that my opponent, Micky Adams is solid but also an all-around player.
Also, with 6 out of 7 previous games having ended in a draw, I wasn't all that
optimistic about my chances before the game.} 1. d4 Nf6 2. c4 e6 3. g3 {
In the only game I managed to beat Micky I have also played the Catalan.
Having this nice memory in mind, I thought it was a good choice also for this
game.} d5 4. Bg2 dxc4 5. Nf3 c5 {I expected this as my opponent used it twice
before. In our previous encounters I faced the more classical systems 4...Be7
and 4...Bb4+.} 6. O-O Nc6 7. Ne5 Bd7 8. Nxc4 $5 {A somewhat forgotten line,
but I remembered having some problems analyzing this from Black's point of
view, so I thought it could be interesting to try it as White.} cxd4 9. Bf4 Be7

White sacrificed a pawn to keep this strong knight on d6, at least for a while.
Of course with an engine running it's easy to prove that Black is objectively
fine, but during the actual game where there are many pieces on the board and
with such an unsafe king it's quite dangerous for Black. There is a funny
hidden story connected to this idea - just before Isle of Man I played the
European Club Cup in Greece and at some point I thought that I would like to
have it analyzed a bit more carefully. It turned out that all my friends with
whom I'm usually working with were not available. So I decided to ask my wife
to check this line for me. She was there with me and didn't play so I
disrupted her holidays but after all we both agreed it was worth it:)} (15. Nd2

all pieces on the board it's not simple to make a right choice.} (15... Bxd6 $2
