{Although this last round game started early, and I was still rather sleepy, I
was also in a determined frame of mind, especially as a win in the match would
earn us the silver medals.} 1. c4 {Here my opponent thought for a while.
Obviously, he too did not want to play the Grunfeld.} c5 2. Nf3 Nf6 {Here I
started to worry a bit. Was he going to play the gambit line, which I had not
prepared seriously?} 3. d4 {Despite the fact that I achieved a virtually
winning position against Nielsen with 3.Nc3 d5 4.cd Nd5 5.e3, I did not feel
like playing this type of position again.} cxd4 4. Nxd4 e5 {This line suits
Emile's style. Black frequently gets a strong initiative. In my fear, I
remembered a more or less solid line that I had once prepared.} 5. Nb5 d5 6.
cxd5 Bc5 7. N5c3 O-O 8. g3 {8.e3 is more popular. While my opponent was
thinking, I started trying to assess various lines. After 8...e4 White replies
9.Bg2 e3 10.Bxe3 Bxe3 11.fxe3 and once he puts his queen on d4 to defend the
e3 pawn against Ng4, he has the resource Nd1. This cheered me up more than I
can say.} Qb6 (8... e4 9. Bg2 e3 10. Bxe3 Bxe3 11. fxe3) ({The guru of this
variation, Rafael Vahanian, has played} 8... Ng4 {here. In view of the fact
that it is not in my nature to give a pawn so early, I advise the reader to
investigate the subtleties of this approach for himself.}) 9. e3 Bg4 {The old
European custom of saying "Garde" when attacking the opponent's queen has
resulted in her majesty being mistakenly called by this French word in the
parks of Yerevan.} 10. Be2 Bxe2 ({After} 10... Bh3 {the reply} 11. g4 {looks
strong, threatening to win the bishop by Rg1-g3.}) 11. Qxe2 e4 {Allowing the
d5-pawn to be strengthened by e3-e4 is of course out of the question for Black.
} 12. a3 {I played all these moves quite quickly, because I did not see an
alternative.} ({In the event of the immediate} 12. Nd2 {one must take into
account the attempt to disrupt White's plans with} Bb4 {, whilst I did not
consider the move 12.g4, which has been played by Kortschnoj.}) 12... Nbd7 {
More subtle was 12...Re8 with the idea of meeting 13.Nd2 with 13...Qc7,
temporarily preventing b4.} 13. Nd2 Rfe8 14. b4 {Black is less comfortable
with his bishop on f8.} Bf8 15. O-O {After reaching this position, I was very
happy and was looking forward to my first win of the tournament. My optimism
was strengthened by my opponent's lengthy reflections.} Qc7 {Seeing how
nervous Emil looked, I was not so surprised by this strange-looking move. It
bis hard to recommend anything concrete to Black at this point. I can only say
that my computer wants to play Rac8 and then Qd8, which certainly does not
look so bad.} 16. Bb2 Nb6 {Black tries to change the picture. Certainly, White
must now make a choice.} 17. Nb5 {Played after 10 minutes' thought. Of course,
it was possible to play Rad1 and then f3, but this seemed to me rather tame.}
Qd7 18. d6 {After the game, a group of noisy critics roundly condemned me for
this move. Even my dear friend Petya Svidler, who has often acknowledged his
enthusiasm for my play, was among their number. Did I deserve this reaction,
after not taking on f6 and then playing d6? Now, in the cold light of day, I
am prepared to admit my mistake.} ({In self-defence, I can only say that I
underestimated the strength of the move 20.a4 after} 18. Bxf6 gxf6 19. d6 Re5)
18... Nfd5 19. Rac1 Bxd6 20. Nxd6 Qxd6 21. Rfd1 {I will let you into a secret.
My main reason for preferring this position amongst the various alternatives,
was the memory of an easy win against Carlsen, in which we had the identical
material.} Qe6 {Trying to get rid of the superfluous knight. Black's main
problem is the lack of comfortable posts for his cavalry.} 22. Nb3 Nf4 ({
After for example} 22... Qf5 23. Nc5 Re7 24. Rd4 {Black has an unpleasant
position. It is not easy to defend against Rad1 with the idea of a4. Black
decides to avoid these unpleasantnesses at the cost of allowing a strong
attack on his king.}) 23. gxf4 ({In case of} 23. exf4 Qxb3 {White will face
problems with ...e3; Black would get some drawing chances.}) 23... Qxb3 24. Kh1
{After noticing the nice 24...Rac8 25.Rxc8 Rxc8 26.Qg4 I did not look at other
moves.} Qe6 {The most logical.} (24... Rac8 25. Rxc8 Rxc8 26. Qg4 {[%cal Rg4g7,
Rg4c8,Rd1d8]}) ({After} 24... Qa2 25. Rg1 g6 26. Ra1 {Black's king is very bad.
}) 25. Rg1 {I did not even look at 25.Rc7, fearing the activity of the black
pieces.} f6 26. Qh5 {Threatening Rxg7+.} Nd5 ({On} 26... Re7 {I have it all my
own way after} 27. Rg3 {.}) 27. Rg3 (27. Rxg7+ Kxg7 28. Rg1+ Kh8 (28... Kf8 {
loses after simply} 29. Qxh7) 29. Qxd5 Re7) 27... Kh8 {Putting the queen on g8
is the only defence against mate.} 28. Rcg1 Re7 29. Rh3 Qg8 {The fragile
structure after 29...h6 can hardly hope to withstand the pressure of three
heavy pieces, but maybe this was the least evil.} 30. Qf5 {Now Black is almost
without moves.} Rf8 31. Bd4 b6 32. Rg4 {Now Black loses material.} Rc7 33. Rh5
{White's manoeuvres with his heavy pieces are rather nice.} Ne7 34. Qxe4 Rf7 {
It is hardly possible to suggest a good move for Black now.} 35. Rg1 g6 {
In the vain hope of creating an outpost for the unfortunate knight.} 36. Re5 {
To rook heads to e6.} Nc6 {A blunder. It was possible to resist further,
albeit not for long, with 36...Qg7.} 37. Re8 (37. Re8 Rf8 38. Bxf6+ {decides.})

1. Nf3 Nf6 2. c4 c5 3. Nc3 e6 4. d4 ({During my preparation I was mostly
looking at} 4. g3) 4... cxd4 5. Nxd4 a6 {Now I chose to pass over to the
hedgehog defence. More common is 5...Bb4, but it's also more easy to make
mistakes there if you don't know the variation well enough.Another move played
regulary is 5...Nc6.} 6. e4 {Now the game passes over to the Sicilian by
change of move order. I have played the position with the white pieces three
tiimes, but this was my first encounter from the black side.} d6 {A fully
playable move, but} (6... Qc7 {is a more correct move order. Black keeps more
options open and has not yet decided where to put his black squared bishop.
Now White still has to count on ...Bb4.}) 7. Be2 {A good place for the white
bishop. Here it doesn't disturb the coordination. The d-file remains open and
moreoverit protecxts the g4-square, which stops Black from a later knight jump
to g4.} Qc7 8. O-O Be7 9. Be3 O-O 10. Qd2 b6 11. Rfc1 {An interesting stage of
the game. It was no surprise that a rook would land on c1, but chooseing the
f-rook indicates that he is ready to push a4-a5, thus keeping the rook on a1.}
({Instead} 11. Rac1 Bb7 12. f3 Nbd7 13. Rfd1 Rac8 {get's to a normal hedgehog
position and doesn't cause black any immediate trouble.}) 11... Bb7 12. f3 Nbd7
13. a4 {A well timed a4. White was waiting for ...Nbd7 as otherwise black
could reply with ...Nc6.} Rac8 14. a5 bxa5 15. Nb3 Qb8 16. Nxa5 Ba8 {Black has
been forced to defence and White has created a weakness on a6. So White is
slightly better, but there is difficult to find a good way to continue.} 17.
Kh1 $6 {A typical waiting-move. White stays calm and plays according to the
strategy "safety first". In my opinion this move is a little slow and almost
unnecessary. Instead of waiting for black to make mistakes White should
continue the pressure on the queenside. An excellent move would be} (17. b4 $1
{with the idea of Rcb1 and Black is under continues pressure. As the game
develops Black gets time to consolidate and create counterplay.}) 17... Rfd8
18. Bf1 $6 {Once again a dubious move that gives Black some extra time.} (18.
b4 $1 {Should be played.}) 18... Ne5 {Black has completed his development and
all the standard moves. Now for the first time in the game he passes the
boarder of his third row with one of his pieces. White continues to play calm
and relaxed and doesn't see the danger. Even the next move hepls black and the
white pieces starts getting a bit clumsy placed.} 19. Qf2 Nfd7 {Black protects
the b6-square and moreover prepares ...Rf8 followed by...f5 with dangerous
counterplay on the kingside.} 20. Rcb1 {Better late than never they used to
say, but perhaps White would now better concentrate on stopping blacks
breakthrough on the kingside.} Rf8 $1 {A strong move that most probably came
as a surprise to White. Now the plan b4-b5 doesn't work as black will come
first. Instead White is forced to passiviity.} 21. Qg3 f5 22. exf5 (22. Qh3 {
was an interesting alternative, trying to brake the black advancement a little.
}) 22... Rxf5 {Now there is the threat of ...Nxf3 followed by ...Rxf3 winning
the queen.} 23. Be2 $6 {The Bishop walks back to its previous position to
protect f3, but taking the development of the game in consideration it would
have been better playing} (23. f4 {at once, saving a whole tempo after} Ng6 24.
Bd3 {Maybe blacks best option is to give an exchange with} Rcf8 25. Bxf5 Rxf5 {
Ofcourse black has full compensation for the sacificed material, but White has
at least saved some time compared to the game.}) 23... Rcf8 {Reactivates the
threat of ...Nxf3. There is also the idea of ...R8f6 followed by ...Rg6 with a
very strong attack.} 24. f4 {Forced since after 24.Rf1 the b2 pawnis hanging.}
Ng6 ({Perhaps} 24... R5f6 {was a better alternative with the idea} 25. fxe5 ({
After} 25. Rg1 Ng6 {both the f4 and the b2-pawns are hanging giving black the
advantage.}) 25... Rg6 26. Qh3 Nxe5 $1 {and White has no good answer to blacks
threat ...Bxg2. A possible continuation is} 27. Rg1 (27. Bf1 $2 Rxf1+ 28. Rxf1

Black in view of Whites vulnerable king and uncoordinated pieces.}) 25. Bg4 Nh4

compensation and White is forced to passivity with Rg1.} 27. Rg1) 26... Nc5 27.
Bd4 {At this moment I had 10 minutes left for 14 moves until the time control
standing for a difficult choice. After considering the matter for 7 minutes I
decided not to go for the complications that are to follow after 27...e5.} ({On

A safe move that gives White an exchange, but Black gets an easy-played
position. Maybe it was better to play the more natural} (27... e5 {but in my
timetrouble I didn't get enough time to calculate the consequences and
therfore choose not to take any risks.} 28. fxe5 Rf3 $1 {A strong move thats
wins the white quuen. But as White will get two rooks in exchange it is not
the material but rather the badly placement of White's king that gives Black
the advantage.} (28... Ne6 {is also interesting, but White seems to be fine

seems to me that Black has the advantage after} Nb3 $1 {after which White's
best reply is to give back an exchange on a1. Black gets a material advantage
and good winning chanses. But taking my time trouble and all the complications
in account I think that the game was the best practical decision.}) 28. Bxf5
Rxf5 29. b4 Ne4 30. Nxe4 Bxe4 31. Re1 $2 {Here the rook get under attack at
once and White will be forces to give back the exchange. Better was} (31. Rb2 {
to keep b4 and g2 protected. Black will win the f4-pawn with good compensation,
but White is probably able to keep the position when defending correct.}) 31...

ptotection of the g2-pawn, but Black has all his forces active.}) 32. Re2 $2 {
The crucial misstake. White could still hold on with} (32. Qg4 $1 {after which
Black has some coordination problems to solve.}) 32... e5 $1 {The key move,
that makes the white position fall to pieces.The diagonal down to g7 is now
covered, freeing the knight from g6. In the same time the bishop on d4 is
threatened and the f4-pawn as well. White is lost.} 33. Bc3 {In the
timetrouble White tries to come in to an endgamewith some survival chances,
which he also succeds in. Even though it's not enough it was most probably the
best chance.} (33. fxe5 {loses at once to} Rg5 {and White must give up the
quuen while Blacks attack is to continue.}) 33... Nxf4 34. Rxe4 {The idea of
white's play. He sacrifices back the exchange to ease the pressure on g2.
Indeed he is a pawn down, but not totally without chances, especially when
taking the time trouble into account.} Qxe4 35. Qf3 Qxf3 $2 {A bad practical
decision that makes Black's position more difficult to play and is giving
White counterchances. Generally exchanges favour the side with material gains,
but what is now happening is a pawn race between the White b-pawn and black's
e-pawn where White's prospects arn't so bad. Instead Black should have played}
(35... Qc2 $1 {with continuous pressure. The White queen cannot create any
danger along thye diagonal, but black threatens to to decide the game
immediately with ...e5-e4.}) 36. gxf3 Ne2 37. Bd2 ({Here White could have put
in} 37. Nc6 {but most probably it leads to the same after 37...Bh4. But now
the option of ...Nd4 is eliminated.}) 37... Rxf3 ({Here} 37... Nd4 $1 {was a
strong alternative killing all white's hope of any counterplay.}) 38. Nc6 ({

{Once upon a time in - 1988 the youngsters Gelfand and Smirin created a
memorable game (see - below the annotations after move 15th.). It was
published in the ex-Soviet chess magazine "Shahmati v SSSR" with remarkable
comments -which quoted an opinion of the genius TAL that soon should be find
refutation to the Black's "Hedgehog" structure. I think that Short's play in
this newest game we are going to study proves that White chances are really
better. In the run of the battle we shall mention the very interesting Stohl's
comments about other previous topic games.} 1. e4 ({To our typical middle game

opinion. During 1988 we (the chess readers behind the "iron curtain") saw for
the first time a White's plan for "<<" with a4-a5 supported by Ra1 and Nd4 -
b3 x Pa5. For us, then was impossible to read other foreign - than soviet

winning is hard to say from this point, there is still much dificult play
ahead but Leko was able to convert his advantage. After looking at his games
against the two colombians GMs, Alonso Zapata and Gildardo Garcнa I have the
impression that young Leko, apart from his outstanding theoretical knowledge
has made a great progress in his positional understanding of the game.} Bf2 40.
