{In our first encouter I gambled playing the Petroff with Black, and was lucky
to escape. Now I was obviously in the much more comfortable situation, but
with no real intention to gamble anymore.} 1. c4 c6 {So the Slav. I was
expecting the Schlechter variation likely to happen, as it was a pet line of
my opponent against Levon Aronian in the earlier stage of the GP in Riga.
Still, I wasn't quite prepared for that, as lately my opponent had been trying
almost any opening, most notably 1...e5.} 2. Nf3 d5 3. e3 Nf6 {Aronian has
gotten this very position 6 times against Yu Yangyi, and in all of them he
started with 4.d4 and after 4...g6 tried different setups. However, after 5.d4
other moves were a concern for me, that's why I prefered to start with 5.Nc3.}
4. Nc3 g6 5. d4 Bg7 6. Be2 O-O 7. O-O Ne4 $5 {A surprise. My opponent had
tried before:} (7... a6 8. a4 (8. h3 e6 9. b3 Nbd7 {1/2 (63) Aronian,L (2756)

1.d4 player, after 7...Ne4 I was already out of the book}) 8. Nxe4 {I chose
this not so popular option, mostly because I was hoping for 9...f5 which I
will try to explain later. Obviously there are some alternatives, which are
more pretending to an opening edge.} (8. Qb3 Nxc3 9. bxc3 b6 {I just didn't
want to play this Grunfeld-like position, even if it looks comfortable for
White.}) ({Also I totally forgot about} 8. a4 {which had been played by Bu
Xiangzhi, and annotated by Anish Giri in some episode of NIC. Possibly if I
had recalled that game, I would have gone for 8.a4.}) 8... dxe4 9. Nd2 c5 {
He played it quickly and it was obvious he was in his prep.} (9... f5 {In this
manner my opponent had played against Wei Yi in the World Cup. I remembered
this game because I made a bet about the final result of it with a friend of
mine. Even though Yu had a disastrous position after the opening, he managed
to outplay Wei Yi in the middlegame, so that I lost an easy cash.}) 10. dxc5 f5
11. Rb1 {After some thought I went for this, because I wanted to get my rook
and black-squared bishop back to business. There are other moves, but only
with a rather modest engine's plus, which is a rarity in standards of the
Schlechter variation.} (11. Nb3 Qxd1 12. Rxd1 Bd7) (11. Qc2 $5) 11... a5 12. a3

depth, suggests the following variation:} Nd7 15. Qb4 Nb8 16. Qb3 {with a
repetition :)}) 14... Qxd1 15. Rxd1 {I was pleased with my position.
Temporarily I'm a pawn up in a safe endgame, where I'm playing for two results
only. However, Black is very solid, and the position objectively is close to
equal.} Nd7 16. Kf1 {Awaiting and getting the king closer to the action.} h5
17. Bd2 $5 {Not seeing a way to make a progress, I decided to sacrifice back a
pawn to activate my pieces.} Rxa3 {Actually the engine doesn't mind this pawn,
and suggests some slow play instead,} ({like} 17... Kf7 18. Bb4 Ne5 19. Na5 Bf6
) 18. Na5 Nxc5 $6 {Even though it felt perfectly natural I was pleased when he
played this.} ({Instead he could have gone for} 18... Ne5 {playing for
activity. The comp evaluates everything close to the infamous 0.00. One
exemplary line is} 19. Nxb7 Bd7 20. Na5 Ba4 21. Ra1 Bxd1 22. Rxa3 Bxe2+ 23.
Kxe2 Rc8 $11) ({or even} 18... Kf7) 19. Bb4 Ra2 20. Bxc5 Rxa5 21. Bxe7 Rf7 (
21... Re8 22. Bd6 {just looks less sensible for Black, as his light-squared
bishop is tied to the b7-pawn.}) 22. Bb4 (22. Rd8+ Kh7 23. Bb4 Ra8 {is the
same.}) 22... Ra8 23. Rd8+ Kh7 24. Bd6 $1 {Basically the only try, with a
hidden tactical idea.} Rd7 $2 {And he fell for it.} ({The way to solve all
problems was} 24... Bf6 25. Re8 Rg7 $1 {and as Black is going to trade all
rooks, White's advantage is kept to the minimum:} 26. c5 Rg8 27. Rxg8 Kxg8 28.

Black is holding his own.}) 33. Bxf3 h4 $11 {and White has some pressure, but
it should peter out to a draw.}) 25. Rxd7 Bxd7 {He looked magnificently in my
eyes thinking we were about to agree to a draw, but missed my next move
altogether.} 26. g4 $3 {Two exclams for the combo of strength of the move,
surprise effect and the punch on the most controlled square (g4) in the
position. Now he sank into deep thought for over 30 minutes.} fxg4 {Relatively
best.} (26... hxg4 27. Rxb7 Bc8 28. Re7 $1 {Here for some strange reason (in
contrast to the game) this is crushing.} Kh6 29. c5 $18) (26... Ra1 {During
the game I thought this may be the best for Black.} 27. Rxa1 Bxa1 28. gxh5 gxh5

this position. A deeper investigation is required}) (26... Bc6 27. gxf5) 27.
Rxb7 Bc8 28. Re7 $2 {I saw I was winning the pawn, but the position becomes
drawish.} ({A better attempt would have been} 28. Rc7 $1 {After that I didn't
see how to proceed after} Kg8 29. c5 Be6 {and indeed there isn't anything
concrete, but I have the choice between prospective possibilities like} 30. Re7
(30. Kg2) (30. Bb5) 30... Bd5 31. Bb5 {and White is pressing.}) 28... Kh6 $1 (
28... Ra1+ 29. Kg2 Re1 30. Be5 Rxe2 31. Rxg7+ Kh6 {and I didn't see a
follow-up, but had a feeling there might be some ideas connected with the
unsafe position of the black king.} 32. Rg8 Be6 33. Rh8+ Kg5 34. Re8 Bd7 $1 (

and it is very drawish, but obviously after a bit of suffering.}) 29. Bf4+ g5
30. Bxg5+ Kxg5 31. Rxg7+ {I had clearly overestimated my position. Black's
active rook and prospects of kingside play are sufficient for equality.} Kh4

Unbelievable!} ({Black had to free his rook from the pin with} 32... Ra1+ 33.

objectively it's just a draw.}) 33. Bxg4+ $1 {It was clearly a terrible moment
for Yu. Not only he blundered the tactics on the very same square again (and
again on the most secured in the position!), but also it made him flying home.
A disaster... I didn't really believe in 32...Kh3 because I thought that 33.
Kg1 is winning as well, and even dared to say in the interview after the game
that 32...Kh3 is the biggest mistake my opponent had ever made. Only on my way
back to hotel, I did realise that after the exchange sacrifice is just a
fortress.} (33. Kg1 Ra1+ 34. Bf1+ Rxf1+ 35. Kxf1 Be6 36. Rg5 Bxc4+ 37. Kg1 h4

had been extremely bad for me, as I had scored 0.5 out of 4, and now had to
meet Magnus two times in a row. Fortunately there was a free day in-between,
so I allowed myself to forget about the tournament for a while. I was also
largely surprised by quite some interest of my supporters in Poland, who
believed in a positive score for this game, possibly more than I did!  Der
Turnierstart war extrem schlecht für mich gewesen, denn ich hatte 0.5 aus 4
und musste nun zweimal nacheinander gegen Magnus antreten. Zum Glück gab es
dazwischen einen freien Tag, daher erlaubte ich mir, das Turnier eine Weile zu
vergessen. Ich war auch ziemlich überrascht von dem beträchtlichen Interesse
seitens meiner Fans in Polen, die an das positive Ergebnis in dieser Partie
glaubten, womöglich mehr als ich!} c6 {The surprise was in the air, but the

But this was a real shocker. I have always found it difficult to believe in
this system, even though I have given it a try a few times myself. Magnus
might have been inspired by L'Ami's chessable course on the Caro Kann, where
among others this variation was included. I was lucky enough to have a quick
look on a short & sweet version (a free and limited one) of the course before
the tournament, so at least I wasn't completely caught unaware.  Aber das war
ein echter Schocker. Es ist mir immer schwer gefallen, an dieses System zu
glauben, obwohl ich es ein paarmal selbst versucht habe. Magnus war womöglich
inpiriert von L'Amis chessable-Kurs zu Caro Kann, der unter anderem diese
Variante beinhaltete. Ich hatte das Glück, vor dem Turnier kurz einen Blick
auf eine Short&sweet-Version des Kurses (gratis und begrenzt) zu erhaschen,

{This was the Semi-Finals of the World Cup 2021. The first two games in the
Classical segment had ended in draws. The first rapid game of 25+10 had also
ended in a draw. This was the 2nd rapid game and Magnus having the white
pieces was naturally quite ambitious.} 1. e4 c5 2. Nf3 d6 3. Bb5+ {This is a
typical Carlsen move where he doesn't go into deep and sharp theoretical lines
of the open Sicilian, rather with Bb5+ he is able to keep the game in
positional territory and at the same time keep pressure on his opponent.} (3.
d4) 3... Bd7 {Duda's main aim in the game as he explains on ChessBase India
was to exchange as many pieces as he could and keep the game simple. A draw in
this game was a good result for him.} 4. Bxd7+ Qxd7 5. O-O Nf6 6. Qe2 (6. Re1 {
is the main move in the position. Qe2 is the second most popular.}) 6... Nc6 7.
c3 e6 {A standard idea to meet d4 by White with cxd4 cxd4 and d5.} (7... e5 {
is a move that you would like to play in order to stop d4. However, you cannot
nip that move in the bud for long. White goes} 8. Rd1 $14 {and d4 is coming up.
}) (7... O-O-O) 8. d4 cxd4 9. cxd4 d5 (9... e5 $2 {is a positional error
because you want to place the pawns on the opposite colour of your bishop on
f8 and not on the same colour.}) 10. e5 Ne4 (10... Ng8 {is also possible here.
It seems like an undeveloping move, but the idea is to reroute the knight to
f5 via e7.} 11. Nc3 Nge7 12. Be3 Nf5 $11) 11. Nbd2 Nxd2 12. Bxd2 Bb4 $5 {
Following the strategy of exchanging pieces. This is an interesting moment in
the game. On one hand Black has the better bishop because the central pawns
are not on the same colour as the bishop here. On the other hand, Black is low
on space and exchange of pieces is to his advantage.} (12... Be7 {Duda made an
important point here. He said that a few years ago, this position would have
been round about even or even slightly better for Black. But in recent years,
space advantage has assumed more importance for the engines. The fact that
Magnus Carlsen has played this opening in such an important game shows his
trust in this position as White.}) 13. Bf4 (13. Bxb4 Nxb4 $11) 13... O-O 14.
Qd3 Be7 {Getting ready to chop off the knight on g5 and also clearing the b4
square for the knight.} 15. a3 (15. Ng5 Bxg5 16. Bxg5 Rac8 $11) 15... Rac8 16.
g3 {Magnus's plan starts to become clear. He wants to play h4, Kg2, switch his
rook to h1 and launch an attack on Black's king with Ng5 ideas. For Duda, the
problem is that his position looks very nice on the surface, but he needs to
come up with a concrete plan for activity.} Na5 17. b3 {Stopping Nc4.} Qc6 18.
Bd2 {The knight on a5 is attacked and has to be defended.} Qb6 19. Rfb1 {
This looks slightly uncomfortable, but moving your pawn to b4 is not a great
idea as it gives up the c4 square and Rab1 loses the a3 pawn.} a6 {This is
part of Duda's plan. As we will see, this move is useful to play Qb5 in future
to dislodge the strong queen on d3.} 20. Kg2 Nc6 21. Re1 {Magnus realized that
Duda wants to offer a queen trade with Qb5, that's the reason why cleared the
b1 square.} (21. a4 {Trying to stop Qb5 gives up the b4 square.} Nb4 $15) 21...
Qb5 $1 (21... f6 {is not a good move in the position. You shouldn't be
touching your pawns on the kingside if not provoked.} 22. exf6 Rxf6 23. Ng5 $1

a3 is weak.}) 22... Rc7 23. h4 Rfc8 24. Ra2 (24. Ng5 Bxg5 25. hxg5 Nxd4 $19) (
24. Be3 Na5 $17) (24. Rh1 {was possible.}) 24... a5 $5 {Duda tries to be
slightly more ambitious here. If White goes a4, then Black gets the b4 square.
Otherwise Black will go a4 and try to fix the weakness on a3 and get the c4
square for himself.} (24... Qb6 25. Rd1 $5 (25. Qd3 Qb5 26. Qb1 $11) 25... Nxd4

inferior position.} (27. g4 {This does look too risky, but White has to
unleash himself on the kingside.}) 27... Na7 $1 {The knight is going to b5
where it will attack the a3 pawn as well as the c3 square.} (27... f6 $2 28.

bring it to e1.} Qc4 $5 {Duda's idea is to play Qb3 to offer a trade of queens.

c-file open.}) 30. Re3 {Magnus stops it.} Nb5 31. Rd3 {Defending the d4 pawn.}

from where the bishop will attack the d4 pawn.} 32. Rb2 Bd8 $1 (32... f5 {

thought for a bit before executing his move Rxc6, and that's when Duda saw
that Rc5 is also possible. Although this move does not change the evaluation
of the position - black is still better. However, it does make Black's task
quite difficult.} Bxc5 (37... Qa6 38. b5 $18) 38. dxc5 R6c7 39. Nd4 Qc4 40. f3

Ghosts as they say!}) 39. Nd2 Nxd2 40. Rxd2 Qc6 41. Qe2 $1 {The point of this
move is to play g5 when h5 won't be possible.} Rc3 42. Ra2 $2 {This is just
too passive.} (42. g5 $1 {Good or bad Magnus had to go for this.} h5 43. Qxh5

other drawback of Ra2 is that now White cannot go Qg4 as the rook on a2 is
hanging.} 45. Qxc4 (45. Qd2 Bb6 $19) 45... dxc4 (45... Rxc4 $19 {With the king
coming to g6, this position is lost for White. But when you are playing a game
which is of great importance, sometimes you just want to be extra sure that
you are winning and hence, your conversion is not the smoothest.}) 46. d5 $5 {

not be clear as to white this move is so strong. The main idea is to break the
kingside pawn structure for White and also fight for the h8-a1 diagonal.} 50.

f2 or f1 it can quickly move to d2 and win.} (50. Kf2 $1 f6 51. exf6 (51. gxf6
