White: G.Kasparov
1.Nf3 |
Black: IBM Deep Blue
|
| This is the favorite move of Kasparov's pretender
to the throne - Kramnik. |
|
|
d5
A standard reply staking a claim in the centre |
2.g3
An unusual reply from the World Champion, who would have played d4
against any human player. |
|
|
Bg4
Black develops his light squared bishop before erecting a light squared
pawn chain on e6, d5, c6. |
3.b3
Kasparov gives the computer the chance to double his f pawns with 3...
Bxf3 |
|
Nd7
The computer declines the offer since after 3... Bxf3 Kasparov will
recapture 4.exf3 when the bishop pair and the chance to undermine the Black
centre with a subsequent advance of the f-pawn will give the World Champion
an advantage. The rules of development state that you should develop your
kingside pieces before your queenside pieces. Here the computer rejects
the rules!! |
4.Bb2
Kasparov continues to play in hypermodern style, putting pressure on
the centre from the wings. |
|
|
e6
Strengthening his centre and preparing to mobilise the kingside. |
| 5.Bg2 |
Ngf6 |
| Finally the computer gets around
to developing his kingside. |
| 6.0-0 |
c6 |
| Kasparov was probably disappointed
that his passive opening failed to provoke the computer into the advance
c5 which gains space, but weakens the diagonal h1 to a8 and allows white
to increase the pressure with c4!. |
7.d3
Kasparov finally advances a pawn in the centre and prepares to develop
his queen's knight to d2. |
|
|
Bd6
The computer continues to develop in sensible style. |
| 8.Nbd2 |
|
|
0-0 |
9.h3
The first aggressive gesture by the World champion. |
|
|
Bh5
Computers don't miss threats like that Mr. Kasparov you are going to
have to do better than that!!! |
| 10.e3
Continuing his waiting policy. The computer has played all the natural
developing moves, but will it be able to find a sensible middlegame strategy? |
|
|
h6
10...Re8 looks like a more purposeful move preparing for action in
the centre with e5. Perhaps the computer was afraid of 11.g4 when White
acquires the two bishops after 11.g4 Bg6 12.Nh4 and 13.Nxg6. However Black
would have a very solid position after 13...hxg6 - Grandmaster McDonald. |
11.Qe1
Breaking the pin and once again asking the computer - 'What are you
going to do?' Garry left the room on the 35th floor and went into his private
room. |
|
|
Qa5
A clear mistake. The queen should certainly not be on this side of
the board - IM Pein. |
12.a3
This move rules out 12...Ba3 - a standard theme in these positions
which forces the exchange of the dark-squared bishops - GM McDonald. Garry
is ready to hit the queen or expand on the queenside with b4. |
|
|
Bc7
The computer anticipates the advance e4 threatening e5 forking two
black pieces and so retreats his bishop. However it was better to stand
his ground in the centre with 12...e5 or admit his mistake on the last
move and play 12...Qc7 - increasing his control over the e5-square. Deep
Blue is still unsure what to do, this is not a good move. Qc7 or a rook
to the centre was better. |
13.Nh4!
This is a big move, the threat is 14.g4 Bg6 15.Nxg6 when White has
some advantage due to the fractured Black's pawn structure. |
|
|
g5
With 13...g5 Black prevents the variation in the last note. However
the remedy looks worse than the disease. - GM McDonald. Malcolm Pein felt
that this was horribly weakening but actually the best move. 'It's here
that the computer's lack of positional knowledge is an advantage. Most
humans would reject this because of the weakness of the kingside but it
turns out that Deep Blue's extra space and the inaccessibility of f5 to
the white knights makes the position perhaps only slightly better for White'. |
14.Nhf3
Kasparov retreats his knight, content with the positional weakening
of the computer's king. According to the newsgroups, Karpov calls this
position strategically won for White. |
|
|
e5
Black blocks the dark-squared diagonal since the bishop on b2 is looking
fiercely at his king. However Black has left a nasty hole on f5 which would
be a fine outpost for a white knight - if Kasparov can get one there. |
15.e4
Staking his claim in the centre and consolidating his hold over the
f5-square. |
|
|
Rfe8
Black anticipates an attack on his centre after 16.exd5. |
16.Nh2
Garry has a huge traffic jam to clear to get a knight to f1-e3-f5.
This is a far-sighted move. Kasparov wants to manoeuvre his knight to f5
via f1 and e3 - after first moving his queen and rook. However this will
take a considerable amount of time. Can Black do something fast to exploit
this? |
|
|
Qb6
GM Yasser Seirawan, commentating to the audience at the Equitable Center
said: 'This is a waste of tempo, the queen was fine on a5. Garry is taking
quite some time as he wants to punish the computer for the loss of tempi'. |
17.Qc1
Beginning the plan outlined in the note to move 16. |
|
|
a5
Gaining space on the queenside. |
18.Re1
Freeing up f1 for the knight, but reducing his defence of the f2-square. |
|
|
Bd6
Black immediately tries to take advantage of White's last move by bringing
his bishop to the aggressive c5-square. Watch this piece, its activity
nearly wins the game! |
| 19.Ndf1
'Now I think White's plan looks a bit dubious. Perhaps he should try
19.Nhf1'- GM McDonald. |
|
|
dxe4 |
| 20.dxe4 |
|
|
Bc5
Now Black has unpleasant pressure against f2. |
21.Ne3
The only way to meet the attack on f2. 21.Qd2 This can be answered
by 21...Rad8. In good computer style the f5 weakness is covered tactically
by the weakness of white's f2-square. |
|
|
Rad8
Rad8 completes development. |
22.Nhf1
Recentralising his knight. |
|
|
g4?
'This move gave me a lot of pleasure' - Kasparov. Black really weakens
his position, seduced by the weakness of f2. An incredible move though
-only a computer would rip open his own kingside in order to attack!! |
| 23.hxg4 |
|
|
Nxg4 |
| 24.f3
If 24.Nxg4 Bxg4 25.Ne3 Bh5 26.Bc3 with advantage - Kasparov. |
|
|
Nxe3 |
| 25.Nxe3 |
|
|
Be7!!
Missed by Garry and of course everyone else. The Bishop gives up a
dominating post to take up an even better one. In raw tactical terms, when
the bishop is on c5 White can unpin in one move with Kh1. On g5 the bishop
pins the knight to the queen and Garry must contort with Re2 and Qe1 to
get out of the way. This introduces some more possibilities based on the
fact that the Re2 is then vulnerable to the Bh5. |
26.Kh1
Breaking the pin of the black queen on the e3-knight. At this point
Garry had a couple of long thinks. He was acutely aware that tactically
he might be vulnerable. In fact after the game he said he saw all the way
to 32.g6 and assessed it as OK. He is obviously in tune with machines,
everyone from beginner to GM was stunned by 28...f5. |
|
|
Bg5
The pressure on the e3-knight is now very unpleasant. |
| 27.Re2 |
|
|
a4 |
| 28.b4 |
|
|
f5
Only a computer would dare! A spectacular move, which attempts to overwhelm
White in the centre. Black threatens 29...fxe4 and so White's reply is
almost forced. Black has to 'do or die' as 28...Nf8 29.Qe1, frees White's
knight on e3 to go to c4 or f5, and looks clearly good for White. |
29.exf5
IM Maurice Ashley, also commentating at the Equitable Center, in his
own inimitable style exclaimed that Kasparov was going to be playing 'rope-a-dope'. |
|
|
e4
This is the computer's stunning idea, but.... |
| 30.f4
This is all forced. Kasparov sacrifices the exchange!!! He strives to
beat off the Black attack and in the long-term take advantage of Black's
weak dark-squares and king position. |
|
|
Bxe2
Taking the material. If 30...Bxf4 then 31.gxf4 Bxe2 32.Qg1 Kh7 33.Re1
Bh5 34.Qh2 Bf7 35.Ng4 h5 36.Qh4. 'When I played b3 I was not sure what
to do with my bishop. Now (after ...f5) it found a job. It was multidimensional,
it controlled the diagonal, and it came to c3.' - Kasparov. |
| 31.fxg5 |
|
Ne5
Black plays for the attack. If 31...hxg5 32.Nd5 wins on the spot 32...cxd5
33.Qxg5+ mates. |
32.g6
This is better than 32.gxh6 when Black will obtain a decisive attack
after 32...Rd6. |
|
|
Bf3 |
33.Bc3
A key move preventing Rd2. White controls all squares from d5-d1 but
33.Qe1 was interesting but only for a correspondence game, it could have
been suicidal against a machine when in time pressure. Garry had less than
30 minutes. If here 33.Qe1 then Bxg2+ 34.Nxg2 Qb5 35.Qxe4 Nc4 36.Qf4 Nxb2
37.Qc7 is winning. The danger of playing against a computer is illustrated
by the variation 33.Qe1 Bxg2+ 34.Kxg2 Nf3 35.Qc3 Rd2+ 36.Kh3 Rh2+ 37.Kg4
h5+ 38.Kf4 Qc7+. |
|
|
Qb5
33...Qc7!? planning to bring the queen over to the kingside runs into
34.Qb1! with the idea of 35.Qa2+. |
34. Qf1
Offering the exchange of queens, after which the passed pawns become
the decisive factor in the position as White no longer has to be afraid
of an attack against his king. 'I was happy to exchange queens, there was
no chance to lose' - Kasparov. White's structure with the knight on e3
and pawns on f5 and g6 is almost impossible to shift. |
|
|
Qxf1
Black does best to avoid the exchange of queens with 34...Qb6. After
the exchange of queens White has it all his own way. |
| 35.Rxf1
|
|
|
h5 |
| 36.Kg1 |
|
|
Kf8
Black can only wait while White improves his position and prepares
to advance his passed pawns. Deep Blue dithers - it's a classic anti-computer
position with no activity readily available, and no clear plan. |
| 37.Bh3! |
|
|
b5 |
| 38.Kf2 |
|
|
Kg7
It's hard to understand this. Perhaps Deep Blue thought its h-pawn
might be vulnerable. This walks into a pin and simplifies Kasparov's task
by allowing him to break though on the kingside with his next move. |
| 39.g4
Kasparov looked very confident. |
|
|
Kh6 |
40.Rg1
This threatens g5+ and so forces Black into a mass exchange on g4 after
which the passed pawns become unstoppable. Murray Campbell now took over
as program controller from Feng Hsu. Kasparov had 3 minutes and 54 seconds
left when he made his 40th move. |
|
|
hxg4
The clarification of the position frees White's pawns and gives him
a won position. |
| 41.Bxg4 |
|
|
Bxg4 |
| 42.Nxg4+ |
|
|
Nxg4 |
| 43.Rxg4 |
|
|
Rd5 |
| 44.f6
It's termination time!! |
|
|
Rd1 |
45.g7
Time to pull the plug. Murray Campbell resigned for the computer at
18.46 Eastern time. |
|
|
Black Resigned |
| 1 |
0 |
| After 45...Kh7 46.f7
White will soon have a new queen. |
