{The match was played in round 9 against the former Olympiad winners, China!
They had not being playing well and my opponent Li Chao had just lost a
winning position against Nigel Short in the previous round with White! The
match decided who would have the chance to play for a good place in the last
two rounds.} 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 b6 {This line is becoming

{[%mdl 2]} 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Nf3 b6 5. Qc2 {This apparently
came as a suprise to Ivanchuk, even though I played it against Anand in round
6. It might have something to do with the fact that I achieved very little in
that game.} Bb7 6. a3 Bxc3+ 7. Qxc3 {All of the three main moves here, d6, 0-0
and Ne4, were tried against me in Bilbao. Regrettably, I did not show the same
versatility, only employing two of the three possible setups from this
position (no e3, Be2 and so on).} Ne4 8. Qc2 f5 9. g3 Nf6 {A case could be
made for including 9... 0-0 10.Bg2 before making this move, which will anyway
be necessary because of Ng5 or Nd2.} 10. Bh3 {Suddenly experiencing a burst of
creativity, I decided to try and exploit the extra opportunity. The main idea
behind this move is to be able to drive away the black bishop from e4 after ...
Be4 Q somewhere, without exchanging bishops.} O-O 11. O-O a5 {A far from
obvious move, which Ivanchuk made immediately.} (11... Qe8 12. d5 {is similar
to the game.}) (11... Be4 12. Qc3 Qe8 {was quite interesting however. Now Nd2
is bad due to ...Qh5, so I was going to continue playing creatively with} 13.

move Black is in serious trouble.} (14... d6 {looked much more logical to me}

ok.}) (14... Qh5 15. Bg2 exd5 16. Nd4 g5 {was given as interesting by online
commentators. My decision to not delve deeper into it should be attributed to
laziness, not arrogance.}) 15. Bxf5 dxc4 (15... Ne4 16. Bh3 {looks pretty cool
for White too.}) 16. Ng5 $1 {The point. Now all kinds of tricks are possible.}

cooler head, I might have come close to considering} 17. Rd4 $1 Rae8 18. Bd2 {
when Rh4 next will be hard to meet.}) 17... Kh8 {I quickly realised that this
was the only move, but I thought there should still be some relatively easy

mistake. Unfortunately, I was not able to coolly give up the exchange without
finding a forced win.} (18. Rad1 $1 Nxd7 19. Rxd7 Nc5 {What else?} 20. Rxc7
Rad8 21. f3 {and White is dominating.}) 18... Nd5 19. Bg4 $6 {Another step in

advantage here, and with the open black king White certainly has the easier
game.} Rf7 26. Rd1 Re8 (26... c3 {would have been an interesting try, but it's
probably no better than the game continuation} 27. h4 $1 (27. bxc3 Nc5 {
is fine for Black}) 27... c2 28. Rd7 Nc5 29. Rxf7 Kxf7 30. Qc4+ Ke7 31. Qxc2 {

By now Ivanchuk had got really short on time, which was not making his job any
easier.} Nc6 $2 {After this Black can hardly defend.} ({The best chance was}

there is still all to play for.}) 31. Rd5 Ne6 32. Qc4 (32. Qa4 {would have
been even stronger, but for some reason I did not consider this move at all.

decisive factor.} Ng7 {Ivanchuk was visibly shocked when I captured his bishop,

Wдhrend der EM hatte ich eine einfache Routine bei der Vorbereitung; abends
verschaffte ich mir einen Ьberblick ьber die Erцffnungen meines Gegners und
ging dann am nдchsten Vormittag an die konkrete Vorbereitung der Varianten. Am
Abend vor dieser Partie stellte ich fest, dass dieses System das einzige ist
mit dem ich mich ernsthaft beschдftigen sollte, hatte das aber bis zum
nдchsten Tag schon wieder vergessen... In letzter Zeit gewinne ich solche
Partien glьcklicherweise hдufig und lerne danach, wie die Erцffnung eigentlich
funktioniert...} ({Heutzutage wird man fast nur noch mit} 7. Bg5 {konfrontiert.

Vorraussetzungen fьr einen Kцnigsangriff.} 10. Bd3 {Wohin der Lдufer
entwickelt werden soll, ist Geschmackssache. Nach Bd3 kann WeiЯ den Ne4 mit

Lдnderkampf, in der ich zum ersten Mal mit diesem System konfrontiert gleich

die normale Fortsetzung fьr Schwarz ist, allerdings ohne mich weiter damit

engines. They provide little help as they do not understand that pushing the
extra pawn to a2 with Black's rook on a1 does not win once Black exchanges the
e5-pawn for his f7-pawn. (And there is no better way to activate Black's
locked king.) Moreover, even a position like Kg2, Ra5, f2, g4, h2 x Kf6, Ra1,
a3, e6, g5, h6 seems to be drawish. If needed, White White can sometimes play
h3-h4 gxh4 f2-f4 to prevent Black's king from supporting the a-pawn. I
produced about two pages filled with variations, but suspect that most readers

accomplished with an early Rd1 followed by Rxd4-f4! Also worth noting is Ivan
Sokolov's impressive performance against Emms with an early Rd1, though
Sokolov played the position without a2-a3, a move that Seirawan always inserts.
All of this raises questions; Is Seirawan trying to avoid lines with ...
Nc6-a5? Why does Sokolov hurry the R to d1when his idea is to play exd4? Why
does Seirawan not hurry the R to d1 when his idea of using the open d-line
caused so many problems?  Hopefully further adventures in this sharp system

enough procedure for gaining space on the white squares. However, without
trying to look too hard at the theoretical assessment, suffice to say that
black's rash 19th move suggests that he later found the mobile pawn on c5 an
inconvenience.} 14. c5 a5 15. Rfc1 Qb8 16. Bf1 {A standard procedure for
preparing to attack the bishop on e4. Of course white must avoid the exchange
of light-squared bishops at all costs.} h6 (16... Qb7 $5 {[%cal Yf3d2,Yf3g5,

feeling that the bishop is sorely missed from the a8-h1 diagonal.}) 17. Nd2 Bg6
18. e3 a4 19. Qd1 dxc5 {Smacks of impatience. However, white has clearly
neutralised black's hoped for light square initiative in any case, and the
bishop pair and space advantage offers excellent long term prospects. am
reminded of the discussion ( inspired by John Watson ) from my previous column
on 'Combatting the Bishop Pair' in which it was mentioned how often,
apparently in contradiction of the recieved wisdom, black follows up conceding
the bishop pair by going on to open the position. The justification was
two-fold. As well as the fact that the immediate compensation for the bishops
often took the form of a developmental plus, the sort of 'temporary'
initiative which will dissipate if the position remains closed, there was also
the claim that an opening of the position is necessary for knights to find the
kind of outposts essential to their well-being. This is very much the crux of
the matter here. 19...dxc5? is not so much a full opening of the position as
the opening of a diagonal which scarcely contributes to black's knights' hopes
of finding good squares. It is the failure to find outposts which eventually
sees black's pieces driven back in a kind of spatial nightmare scenario.} 20.
