Fritz_X3D
(2675) - Garry Kasparov (2830)
[D27]
Human vs. Computer / Man
vs. Machine W.C.M.
Match
played in Virtual Reality/3D ... at the Athletic Club
New York, NY; {U.S.A.} (Game # 4), 18.11.2003
[A.J.
Goldsby I]
One of the most critical games of
the entire match. Since the score
is currently tied, to lose would be a
huge disaster for either party.
Garry ... normally ... would be out
for blood, especially against a human
opponent. Many predicted that Kaspy (Kasparov)
would do exactly this - that he would
go 'all out' for a victory. However, I
counseled all my friends and such -
in an email sent out the day BEFORE the game - that Garry would indeed
try very hard. But he also would come
prepared with a line - that in his own
estimation, and not those of the many
commentators - would allow him to
keep (a) "draw in hand."
I have tried to concentrate here on the
general ideas and verbiage of this game.
If you want to see a "theoretical"
discussion, (all the applicable games of
the line that was played in this game);
- I suggest a good book on the Q.G.A.
(You can also see the many excellent
links and other jobs of annotations of
this game that were done on the
Internet.)
***************************************************************************************************
1.d4, {Diagram?}
Surprise number one. Seirawan said
that the machine won in 2nd game with 1.e4.
So why change?
The simple answer was that game two
was NOT clearly in machine's favor ...
and the programmer's knew this.
(The program was relatively OK
coming out of the opening, but I think
it was clear
that Garry probably
misplayed a very strong King-side
attack!) Of course ...
by now ... Garry had pretty
thoroughly analyzed that encounter ...
and may have
come up with some ... possibly very significant ... improvements.
Commentator P. Hoffman correctly
noted that often times it is a very good
strategy to keep your opponent a
little in the dark - and guessing - as
concerns
the opening that you might
actually choose. This also limits the
enormous
preparation that Garry is
very justly famous for.
[ Game two saw the following continuation:
1.e4
e5; 2.Nf3 Nc6; 3.Bb5 Nf6!?; 4.d3
d6; 5.c3 g6!; 6.0-0 Bg7;
7.Nbd2
0-0; 8.Re1 Re8!?; 9.d4, "+/="
{Diagram?}
and the computer had a small but
fairly solid edge.
FRITZ_X3D - GM G. Kasparov;
"Man vs. Machine" W.C.M. (Game #2)
(A chess match played in VR.) /
New York, NY; (USA) / Nov. 2003. ]
1...d5;
Surprise number two. Garry plays
the classical defense to White's QP
opening.
Although I was very shocked by this
move, it does fall in line with what I
had
predicted for this game. (That
Garry would play intelligently
aggressive chess.
He would play a
line that had a lot of preparation behind
it. He would definitely
have something
specific in mind ... possibly even a few
TN's. He would try very
hard for the
win ... BUT! You could almost
guarantee that he would also strive
to keep the draw well in hand.)
Also - Garry's favorite move, at least
when going for the win, has usually
been
1...Nf6. But the programmer's
were aware of this and may have had
a surprise
of their own in the lines
that they had prepared for Garry.
(OVER 2.8 MILLION moves in Fritz's
opening library!!! And many of these
lines
were possibly prepared with
Garry Kasparov specifically in mind!)
Bear in mind that Garry probably had
spent MOST of his preparations in
anticipation of Fritz playing 1.e4 on
the opening move.
[ I was expecting the move:
1...Nf6; {Diagram?}
with possibly a "King's Indian
Defense."
(Garry Kasparov is one
of the world's leading experts
in
this opening.) ]
2.c4,
White immediately pressures the
center and enters the main lines
of the venerable opening known as
the Queen's Gambit.
Of course any simple and/or developing
move could be played by White
at this
point in the game. 2.c4 is not obligatory,
just the most common move
played at
the Master Level.
[ I would be very interested to see
how Garry would have handled a
more simple approach with a move
like: 2.Nf3!?,
{Diagram?}
with possibly a Colle Opening. ]
2...dxc4;
Yet another surprise! Garry plays
the "Queen's Gambit Accepted."
I have a database completely dedicated
to Kasparov's games. A search
of that
collection of games showed that - as
far as I can determine - Garry
has
NEVER played the "Q.G.A." ... from the Black side!!!
(I found dozens of examples with
Garry playing the White side of this
particular opening!)
{Admittedly this database is a little
old ... and contains ONLY serious or
slow chess. It does NOT contain
fast games or blitz matches!}
---> I put out a number of inquiries
to some of my friends, and one has
a very
extensive database - which
he maintains religiously. He said that
Garry HAD
played the Black side of
"The Queen's Gambit Accepted," ...
but only a few times. Apparently
at least one (or two) of these were
BLITZ games,
(5-min.) and another
may have been RAPID chess.
(Game in 30 minutes.)
I don't count
these types of games, they do NOT
go into my database of Garry's
{collected} tournament (and also
match) games.
(This would explain
why they were not in my database.)
----> Apparently Garry had played
the "Q.G.A." ... and one of the games
was
versus his main protagonist ...
GM Vladimir Kramnik. (But to repeat
this was a
FIVE-MINUTE or BLITZ/Rapid
game.) And he did win this game.
{As Black.}
Now the question that begs itself is:
"What is Garry up to?"
And, "Why is
Garry playing this particular defense?"
*******
Without going into an extremely deep
analysis of all the possibilities of the
lines of the "Queen's Gambit Accepted,"
I will simply make the following
statement. ----->
I think Garry was heading or hoping for
lines that feature:
# 1.) Wild sacrifices by White in the
opening phase of the game;
{There were a couple of lines popular
about 10-15 years ago. One of these
featured a number of sacrifices by
White. It is entirely possible that
Garry was
going to try and steer
the game into one of these particular
variations.}
# 2.) Very unclear or murky positions ...
and positions that are not very
thoroughly explored by theory;
# 3.) MOST Importantly! There are
many lines in the Q.G.A. that feature
an
EARLY ENDGAME. Even the many
commentators - like Hoffman - have
specifically noted that the computers
do NOT play endings really well.
(The emphasis is on LONG-TERM
planning, pattern recognition, ...
and NOT on tactics. And as Hoffman
duly noted, game three showed
that
the computer is deficient in these
areas. GM Yasser Seirawan also
noted that some lines of the Q.G.A.
feature early endgames as well.)
*******
****************************************************************************************
Another added point is that the
"opening book" of several versions of
this
program, (i.e. Fritz 7.0); featured bad
or old analysis of this particular opening
variation. I feel relatively certain that
Garry - and his team - must have
noticed
this flaw and aimed to exploit it.
****************************************************************************************
[
The 'main line' ... (of The Queen's
Gambit - {Declined})
and the continuation that is certainly
played the most frequently is:
2...e6;
3.Nc3 Nf6; 4.Bg5 Nbd7; 5.Nf3 c6; 6.e3 Be7;
7.Rc1 0-0;
8.Bd3,
"+/=" {Diagram?}
and White maintains a small ...
but a rock-solid and time-tested
edge.
One of the most recent examples I could find was the following game:
GM Giorgi Kacheishvili (2603) -
T.(2)
Petrosian (2259);
BCSA Open (Tournament)
/ Batumi, Georgia; (RUS) 2003.
(White won in 30 moves.);
*******************************************************************************
By playing the moves:
2...c6!?; 3.Nf3 Nf6;
4.e3 e6; 5.Nc3 Nbd7;
6.Qc2,
"+/=" {Diagram?}
Garry could play the Black side of
the same opening ... that was played
in Game # 1. (But with Garry playing
White, not Black!)
So in effect, Garry would be playing
himself!
Apparently Garry discounted this
particular approach, although it was
enormously interesting to me and
other chess fans around the world.
(But duly noting we are amateurs,
and have little or nothing to lose!) ]
3.Nf3,
This is pretty much the normal move
for White in this position.
It also is
good because it:
A.) Controls the
center;
B.) Develops a piece towards
the middle of the board;
C.) It is
also paving the way for a later K-side
castling by White.
(As Fritz indeed
will play in just a few moves.)
[ Another good - and very sharp
move - is the following:
3.e4!?,
{Diagram?}
with pressure on the center of
the board.
This leads to a completely
different type of game than was
played in this encounter.
I remember annotating several games
with this particular line.
(One
example.)
(A more recent GM
game.) ]
PLEASE NOTE:
I watched the tape of this event
very carefully. It is very clear that
this
is the exact move order of this
game. (Many of the on-line sites
have
an incorrect move order.)
3...e6!?;
Garry now gets a little tricky with
his move order ... but to be honest
it does not really matter (that much)
what move order Black uses!
[ Black can also play: 3...Nf6;
"=" (?) {Diagram?}
{Which would
eventually transpose back to book.} ]
4.e3,
The best move for White,
although other moves are possible
here for the first player.
(Besides the note below, White
can also play a3!?, Nc3, g3,
and also e4 on move four.)
[ In the early days of this opening,
the move: 4.Qa4+!?,
{Diagram?}
was thought to be the best reply.
]
4...a6!?;
Again ... Garry is being very tricky
with his move order here.
In the old days - before hash tables
- the computers would spend a lot
of time, or even lose their way after
little tricks like this. But here Fritz_X3D
hardly pauses before cranking out the
correct ("book") move in this position.
[
It is more usual for the second
player to try the move: 4...Nf6;
{Diag?}
at this point in this line.
{Again - transposing back to book.} ]
5.Bxc4 ,
This is almost guaranteed to be the
best move. It hits all four of the
opening
principles. It re-establishes
material equality. And this piece will
be posted
aggressively on c4 -
pointing somewhat menacingly in
the direction of the
Black King.
[ Playable is:
</=
5.a4!?,
{Diagram?}
(Playable perhaps, but not great.) ]
5...c5!?;
Garry plays with his pawns ...
perhaps hoping to throw the program
off. But Fritz is not interested
in even
attempting to exploit Garry's move
order - and bashes out
its reply
nearly instantly.
[
More normal is:
5...Nf6;
first. (in this position) ]
6.0-0,
The program wisely castles.
This move is also good because
the King is tucked safely away in
the corner
and a Rook is brought
into play from out of the corner.
[ Also playable for the first player
are the moves:
6.Nc3, {Diagram?}
with a good game;
*******
Or even the play:
6.Qe2!?, {Diagram?}
which also gives a nice edge
to the first player here. ]
6...Nf6;
Garry finally develops this piece.
It controls the center, gets a piece
out, and prepares castling.
It also heads back into the main
line for the second player.
[ Garry probably considers the play
of: 6...b5!?;
{Diagram?}
to be much too wild
and too risky for Black in this
position. ]
7.Bb3,
{See the diagram ... just below.}
The favorite move of Garry's (other)
nemesis, GM Vladimir Kramnik.
*************************
*************************
Garry was OBVIOUSLY disappointed
to see this move, I am relatively certain
he was hoping for an entirely different
kind of battle and/or middlegame
position.
At this point Garry put his head in
his hands, one pundit on ICC said
Garry looked,
"as if he wants to cry."
I do not doubt that Garry was both
surprised & shocked -
and probably
more than a little disappointed at
this turn of events. But I think that
what
was really happening was that Garry
was mainly trying to recall his analysis
... he may have had a choice of
several key lines at this particular
juncture of the
game.
Garry is also a good actor. He gave a
small and quick, wry smile, (when this
move
was first played) - that GM
Yasser Seirawan was quick to note.
Yaz duly noted that
this move - Bb3 -
is a favorite ... and was pioneered by
maybe the only player to
defeat
Garry in a set match. (GM Vladimir Kramnik)
Seirawan goes on to note that Garry
is probably thinking something like:
"Did Kramnik help them set the
opening's book up here, or what?"
In the final say, Garry (now) mostly
had the very difficult job of trying to
recall every
game he had ever seen
in this line, and then make a mental
decision of which
variation was the
most suited to his needs.
******************************************************************
[ The most often played
continuation is:
7.Qe2 b5; 8.Bb3!?,
{Diagram?}
This is probably the strongest,
and has supplanted the other
move, (Bd3);
as the main line
at this particular point.
( Interesting was: 8.Bd3!?,
which is the older line.
V. Chekhover - H. Kmoch; Masters Tournament,
Leningrad, (U.S.S.R.); 1934.
(GM Artur Yusupov - who now
spells his name Jussupow - played
this line as recently as 2002.) )
8...Bb7; 9.Rd1 Nbd7; 10.Nc3,
{Diagram?}
Once again, the opening is
about center control and getting
your pieces
developed.
(After 10.dxc5!? Bxc5, "~" {Diagram?}
Black looks OK.)
10...Qb8; ('!')
{Diagram?}
Here Black can play his Queen
to nearly any reasonable square,
(c7, or b6). The second player
also have several other moves,
including moving his KB.
( Playable is: 10...Be7; {Diagram?} and Black should {eventually}
equalize ... with correct play. )
11.d5!? Nxd5; 12.Nxd5 Bxd5;
13.Bxd5 exd5; 14.Rxd5 Be7;
{Diag?}
The end of the column.
15.e4 Qb7; 16.Bg5 Nb6; 17.Rad1!? f6;
18.Bf4 0-0!; {Diagram?}
MCO says that this is better than
taking on d5 ... although I imagine
Garry would love to have given this
line a whirl!
( KEY POSITION, # 1.)
(See the variation just below.)
( Maybe Kasparov wanted to
play the line:
18...Nxd5; 19.exd5 0-0; 20.d6,
"~" {Diagram?}
when White supposedly has
active play - but maybe Garry
feels he can keep the material ... and try to
win. )
19.R5d2 Rad8; "="
{Diagram?}
Black has almost certainly
managed to equalize here.
GM Larry Christiansen
(2585) -
GM Robert Huebner
(2615);
(Bundesliga?)/Germany, 1992.
[ See MCO-14; page # 445,
column # 1, and also note # (e.). ]
*************************
White can also play the move:
7.a4!?, {Diagram}
in this position. The idea is
obviously to prevent
Black from
playing the freeing/space-gaining
move, ...b5.
[See MCO-14; page # 447.]
]
******************************************************************
7...cxd4; ('!')
This is one of the more provocative
strategies that Garry could adopt
here.
(White is given an isolated
pawn - but also many open lines
and also a lead
in development.)
But almost no one - that I am aware
of - has pointed out that this line
avoids the most
promising line for
White ...
simply by Garry using an
intelligent order of moves.
[ Another favorite move here for
the second player is: 7...Nc6!?;
"~" {D?}
and Black also gets a good game.
[ See MCO-14; page # 447,
columns # 7 & 8, and note # (g.).] ]
8.exd4,
Practically the only good move for
Fritz_X3D ... in this position.
[ After the moves:
8.Nxd4!? e5!; 9.Nf3 Qxd1;
10.Rxd1 Bg4;
"=" {Diag?}
Black has no problems in this
position, and could even be a
tad better. ]
8...Nc6;
Once again - Black needs to start
developing his pieces,
although
the try ...Be7 was certainly playable.
[ Was the move:
8...b5!?;
{Diagram?}
playable in this position? ]
The next few plays look to be the
best ... for both parties here.
9.Nc3 Be7; 10.Re1 0-0; 11.Bf4!,
The computer played this move very
quickly - almost instantly. It is very
probably the best move, although a
fairly new book I have on this very
tricky opening ... advises White to
try a3 in this position.
[
Interesting was the try:
11.a3!?,
"+/=" {Diagram?}
when White also retains a small
advantage from the opening. ]
11...Na5!;
Garry too finds the sharpest ... and probably the best move.
[ The continuation of:
</= 11...b5!?; ('?!')
12.d5! exd5;
13.Nxd5,
"+/=" {Diagram?}
yields White a very solid edge
out of the opening phase. ]
12.d5!?,
(Probably - '!')
Absolutely one of the sharpest
moves in this position ... and it could
easily
be the best. (Although this is
not 100% certain.)
The computer also whipped this move
out very rapidly - it probably was
all
part of the prepared 'book' for the
program.
[ Garry may have expected a line
or continuation something like:
12.Bc2!? b5;
{Diagram?}
The TV commentator, GM Yasser
Seirawan commented on this
particular position in one of his
"variations" during the game. He
felt the computer would be quite
happy with this position. While
this might be true, I think Garry
came
well-prepared for this line
as well.
13.d5 exd5; 14.Qd3 g6!; 15.Nd4!?,
"~" {Diagram?}
Here the official {book}
verdict is that ...
"White has very good play."
(From a book on this opening ... that is less than 3 years old.)
This must be someone's analysis.
But no source is listed, and I could
find NO relevant matches in ANY
database.
KEY POSITION, # 2.)
{After 15.Nd4.}
After days of research, I think this
must have been one of the key
positions that Garry had been
attempting to reach! ]
12...Nxb3;
13.Qxb3, {See the diagram just
below.}
The correct reply. White gets his
Queen out and prepares to bring his
other Rook to the center of the board.
[
</= 13.axb3?
exd5; "=/+" {Diagram?}
favors Black. ]
*************************
(The
actual game position after White plays 13.Qxb3.)
*************************
(White has a lot of pressure here.)
Garry now went in for a fairly long
think, consuming over 20 minutes
of precious clock time.
13...exd5!; {Diagram?}
A surprise ... at least for the panel
of commentators.
Garry had been thinking for a fairly
long time here. And during this time,
GM Yasser Seirawan had stated, most
emphatically and repeatedly, that the
ONLY real move here for Garry was
...Nxd5 - preparing the same sacrifice
that Garry had used against Kramnik.
(And to be honest, several experts -
like WGM Susan Polgar - also agreed
with Yaz on this matter.)
Yet while Seirawan was so busy talking,
Kasparov was deep in analysis.
And Garry is not stupid. He has probably
played many 'test' games against the
computer. He knows that the computer
is more than capable of finding the
best
move ... over and over again! It
does not get tired and will not care how
many
times it has to search to find the
best move. Therefore, Garry probably
decided
that giving the computer the
Queen in this position was not the
best choice.
[
All the commentators practically
GUARANTEED that Black would
sacrifice his Queen in this position
with the continuation of:
13...Nxd5!?;
{Diagram?}
This idea was originally an idea
of the
ex-Latvian, GM A. Shirov. (Who now lives in the country of
Spain.)
14.Rad1 Nxf4!?; 15.Rxd8
Rxd8; "~"
{compensation}
{Diagram?}
and Black has good play for
the Queen.
Kasparov used this line to beat
Kramnik in a "Botvinnik Memorial"
Tournament. (In 2001.) But I must
emphasize that this was blitz,
(maybe rapid); and
not slow
chess. ]
White's next move is a consequent
play - and the best move for White.
14.Rad1 Be6; ('!')
While this is practically forced, for
me it would have taken a lot of
courage
to play this move. For after
...Be6; Black's entire Queen-side
is completely
decimated.
[
Less attractive is: 14...Bc5!?;
15.Bg5,
"+/=" {Diagram?}
and White is clearly better.
]
15.Qxb7!,
The best move - and apparently
still a part of the program's prepared
lines ... for it zapped this stoke out
almost instantly as well.
White obliterates Black's Queen-side,
and only PERFECT play by
Kasparov
will prevent him from losing.
This had all been played about a
dozen times before - but not all of
these
contests were at the GM
level of play. Probably the most
significant game
was: GM V. Kramnik - GM V. Anand; Melody Amber "Tourney of Stars"
(rapid-competition, 10th round)
Monaco, 2001.
{The game was a very hard-fought
draw in nearly eighty moves.}
[ The machine could have also
considered playing the move:
15.Nd4!?,
{Diagram?}
which also might lead to an
opening
advantage for White. ]
15...Bd6!;
(TN?)
{Diagram?}
Garry thought for a while ... and
comes up with a large improvement
over known 'book' theory.
However, a friend with one of the
largest private databases in the world
told me that this is originally an idea
of GM Josif Dorfman, and that he ...
(he = Dorfman); has actually used it several times before.
{Whether or not Garry was aware of
this, I am not really sure. He seemed
to be working very hard at the board.
But this could have been just for show.}
*************************
[ All the commentators agreed that
the 'book' continuation was ...Bc5;
at this point. For example:
15...Bc5!?; 16.Be5 Qe7;
17.Qxe7 Bxe7; 18.Nd4 Rac8;
19.Bg3,

*************************
16.Bg5,
This pin looks to be the best move
for White in this position.
Up until this point, the computer
had played almost all of its moves
nearly
instantaneously. (But I think
this must have been the last move
that was pre-
programmed into the
computer's opening book. Because
after this move, the
computer begins
slow down and "think.")
[ 16.Bxd6!?
Qxd6; 17.Qb3 Rab8;
"<=>" ]
16...Rb8;
('!')
The most active move Garry could
play here ... and very nearly forced.
Black has few viable alternatives,
some moves - for Black, here -
will lose horribly.
And at long last, Garry seemed to
have finally gotten Fritz_X3D out
of its
prepared lines - it settled
down and had a nice 'think.'
[ After the (inadvisable) moves:
</= 16...Be7?!; ('?')
17.Nxd5! Nxd5;
18.Bxe7 Rb8; 19.Qxa6 Qxe7;
20.Rxd5, '±' {Diagram?}
White is clearly much better.
(Fritz probably wins here ...
without any undue difficulty.) ]
Now the computer <thought> for
close to five minutes. At this
point Garry even
asked the (FIDE)
Arbiter if the machine's clock was
even running!
17.Qxa6,
This move is practically forced,
and is certainly the only move to
yield White
any advantage at all.
GM's Ashley & Seirawan even
wondered why the machine was
taking so long
to play this seemingly
obvious move. The reason was is
the computer has to sift
through a
number of alternatives, and examine
dozens of lines ... even if they do
not
represent best play. (A human GM
would probably play Qxa6 nearly
instantly.)
[

17.Bxf6!? Rxb7; 18.Bxd8 Rxd8; 19.Re2 Bc5;
"~"
</= 17.Qa7!? Qa5!; 18.Qd4 Bc5;
"<=>" ]
17...Rxb2;
{See the diagram given, just below.}
This must be the only good move
here for Black. (And its not bad.
Black grabs a Pawn and lands a
Rook on the 7th rank.)
*************************
*************************
[ After the moves:
</= 17...Rb6?!;
18.Qe2 h6; 19.Be3, '±'
{Diagram?}
White is clearly much better.
(And would probably win without
too much trouble from here.) ]
Play now proceeds down a fairly
narrow and a relatively forced
path ...
for both parties.
18.Bxf6!?,
(TN) {Diagram?}
This initially looks to be very
promising - and was even the
first choice of
GM Yasser Seirawan.
(Originally Seirawan thought Garry
would have to re-capture with his
Knight-Pawn in this position.)
But this move might take some of the
pressure off Black ... and could allow
him to equalize. But at the same time,
Re2 had been played before ... and
White was only able to draw. So it is
an open question if - or how - White
is
able to actually increase his edge
in this position.
It is also entirely possible ... that this is
the best move ... and that the computer,
which can search over FOUR MILLION
positions PER SECOND, (and thus can
look nearly 10-15 moves deep in some
positions); ... has found some resource
for Black that has been otherwise over-looked by all the pundits!
[ Probably better was the following
continuation, ...
but this is NOT
100 per cent certain:
>/= 18.Re2 Rxe2; 19.Qxe2,
"+/=" 19...Be7; 20.Qd3 Qa5; "<=>"
{D?}
and yet Black had good play and
drew shortly.

Kharlov has worked for Garry's team

the past ... and it is highly possible
that Garry knew the "in's-and-out's"
of this whole line!)

18...Qxf6!;
The best move ... and a surprise for
the group of commentators.
(The first time around, Yaz said if
White captured on f6, then Black
would have to re-capture with the
Pawn.)
[ Not nearly as good was the line:
</= 18...gxf6!?; 19.Qd3, "+/="
{Diagram?}
and White may be able to exploit
Black's fractured
pawn structure. ]
19.Qxd6,
The best move for White.
[
Of course not the silly:
</= 19.Nxd5?? Bxd5; 20.Rxd5??,
20...Bxh2+; "-/+"
{Diagram?}
and White loses the Queen.
(As GM Y. Seirawan pointed
out in his commentary.) ]
19...Qxc3[];
{Box,}
This was forced - Garry had to
regain the piece in this position,
or lose horribly.
20.Nd4!,
The correct move - White ditches
the weak button on the a-file ...
and heads for high ground and
the safety of a draw.
[ Possible was:
20.a4!? Ra2; "~"
{Diag?}
with an unclear position. ]
The next few moves are all pretty
much forced in this position, now
the team of
commentators were
beginning to see that the game
could be drawn.
20...Rxa2; 21.Nxe6 fxe6; 22.Qxe6+ Kh8; {Box?}
{Diagram?}
Practically the only good move.
[ Simply horrible is:
</= 22...Rf7??; 23.Qxd5,
"+/-" {Diag?}
... and now White is winning.
]
23.Rf1,
('!')
{See
the diagram given here ... just below.}
White - of course! - must protect
the sensitive f2-square. But Rf1
was not the
only move, I had
seriously considered Re2 for
White in this position.
I think the computer's move - here,
at this particular juncture - is best.
The machine even thinks to keep
all of its King-side Pawns ... and
perhaps turn its attention to White's
isolated d-Pawn in the near future.
*************************
The
actual position in the game ... just after White played 23.Rf1.
*************************
******************************************************************************
[
Variation # 23W1.)
Also apparently playable was
the move Re2, viz:
23.Re2!? Rxe2; 24.Qxe2 d4!?;
25.Qe7 Qc8; 26.h3,
{Diag?}
White must give some 'luft' to his
King in this position.
( Of course the computer would
NEVER play:
26.Rxd4?? Qc1+; and White will be mated. ("-/+")
)
26...Rd8; 27.Qe4 Qd7;
28.Rd3 h6; "=" {Diagram?}
... This position (also) must be
drawn. (Similar to the game.);
*************************
Variation # 23W2.)
Very interesting was Qf7!?,
but this is (hardly) no better
than the
game, e.g.,
23.Qf7 Qc8; 24.Qxd5 Raxf2; 25.Re7 Qa6;
26.h3 Qb6; 27.Kh2 h6; "~"
{Diagram?}
but I cannot see either side
winning this with best play.
*************************
Variation # 23W3.)
It seems that the capture, (with
the Queen); on d5 ...
was good enough to draw as well.
For example:
23.Qxd5!? Raxf2; 24.h3,
"~" {Diagram?}
and once again we have a situation
similar to the actual game.
(A draw is obviously in sight.);
*************************
Variation # 23W4.)
It is also possible that taking with
the Rook here would have
been
acceptable as well:
23.Rxd5!? Raxf2;
{Diagram?}
The correct capture.
( Not </= 23...Rfxf2???; 24.Rd8+,
("+/-") {Diagram?}
and mate next move. )
24.Red1,
{Diagram?}
One of the safer alternatives.
( But not: </= 24.h3? Qg3; "/+"
{Diagram?}
and Black is clearly better. )
Now after the moves:
24...Qc2; 25.Qg4 h6!?;
26.h3!?, "~" {Diagram?}
a draw is probably the correct
outcome of this position. ]
******************************************************************************
Now one might expect Black to
play something like ...Ra5 and
try to protect his
d-Pawn. Garry
comes up with something much
better.
23...Qc5!; (Maybe -
'!!')
The best move ... with one play
Garry actually accomplishes several
different things:
# 1.) Puts the Black Queen on a
better square.
(Nearer the center,
and protects his Rook on f8.)
# 2.) The Queen now protects the
Black Pawn on the d5-square.
# 3.) Garry sets up some really nasty
threats to White's f2-square.
[
Possible was: 23...h6!?
]
24.Qxd5!,
This move had already been
completely discounted by
GM Yasser Seirawan ...
but it
is definitely the best move for
Fritz_X3D in this position.
{White re-establishes material
equality ... and the game winds
down to a draw.}
(Seirawan - at one point in his
commentary - said this pawn ...
absolutely could NOT be captured!
He even referred to this button as:
"A POISONED PAWN!")
*************************
[ White cannot play the other capture:
</= 24.Rxd5?!,
('?') 24...Qxf2+!!;
{Diagram?}
Definitely the best move.
(Seirawan only looked at:
</= 24...Raxf2!?; 25.Rxc5?? Rxf1#.)
25.Rxf2 Ra1+!;
("-/+") {Diagram?}
and White can give back his
Queen and both Rooks ...
before he gets mated.
*******
I actually expected the move:
24.Qe3!?,
"~" {Diagram?}
but what the computer played
is much, much better. ]
*************************
24...Rfxf2!!;
A super-shocker!
(Black leaves his
Queen hanging ... and grabs a ... NOT-so-free Pawn.)
And it is almost funny.
Many GM's were predicting that Garry
would have to draw the ending of
"Rook-plus-three-Pawns vs. Rook-plus-two-Pawns," but with Pawns
only
on just one side of the board.
Garry finds something even better.
(Although to be honest, Yasser had
predicted the capture on f2 here.)
[ The ending after the moves:
24...Qxd5; 25.Rxd5 h6; 26.g3,
'±' {Diagram?}
is technically only a draw
... but Fritz
(X3D) could
make Garry suffer for a
really long time. ]
25.Rxf2!,
I am sure this is best.
[
Variation # 25W1.)
Many commentators were saying
that it was a mistake to play Qd8+
in this position. But that is simply
incorrect, as the following analysis
will show.
25.Qd8+!? Rf8+;
{Diagram?}
This is forced.
(</= 25...Qf8??;
26.Qxf8+ Rxf8; 27.Rxf8#)
The next few moves are forced.
26.Kh1 Raf2;
{Diagram?}
This is virtually forced.
(Of course not: </=
26...Rxd8 ???; 27.Rxd8+ Qf8; 28.Rdxf8#)
27.Rxf2 Qxf2; 28.h3 h6;
29.Qe7, "=" {Diagram?}
and the position is completely
balanced. (As in the game.).
*************************
Variation # 25W2.)
Naturally - White could NOT play:
</= 25.Qxc5?? Rxg2+;
{Diagram?}
White can only watch what happens
now, as he is unable to protect
the
key squares, and all of Black's
moves come with check.
26.Kh1 Rxh2+;
{Diagram?}
Now White only has one legal
move in this position.
27.Kg1 Rag2#.
{Diagram?}
and White has been mated.
Of course the computer would have
NEVER fallen for this ...
unless there
was a short-circuit or something!! ]
The next few ply are best. (forced)
25...Qxf2+; 26.Kh1 h6;
Black makes an 'escape square' ... for his King, and guards against
any
possibility of a back-rank mate.
At this point - it is obviously a draw.
The computer is ignorant of this and
plays on until the team of 'handlers'
step in and recognize that Garry is
correct - and the game is drawn.
27.Qd8+!?,
This is probably the simplest
method. (And also best.)
[ After the move:
27.h3, "="
{Diagram?}
it is also time for smiles, a shaking
of hands,
and the signing of the score-sheets. ]
27...Kh7;
"="
{See the diagram just below
{See the diagram just below the variation.}
Draw agreed.
[ After the continuation of:
27...Kh7; 28.Qd3+ Kg8!?;
{Diagram?}
A possible winning attempt?
( The continuation of:
28...Kh8; 29.Qd8+ Kh7;
30.Qd3+,
30...Kh8; ("=") {Diagram?} is an obvious draw.
)
29.Qd5+! Kh8; 30.Qd8+ Kh7;
"=" {Diagram?}
... it is very obvious that neither
side can make any progress.
After
the same position has been repeated
three times, either
party can claim
the draw. ]
*************************
(The final position after 27...Kh7.)
*************************
***************************************************************
An extremely exciting and
very well
played game by BOTH man and
machine.
Well done!! In my opinion,
this is easily the best game of the
entire match - both
sides played without any mistakes.
This is easily one of the best draws
I have seen in the last 50-75 years.
Both sides played practically
perfectly! (BRAVO!)
