Editorial Preface
Wijk aan Zee
has begun! Both the A and the B group are
very exciting with a lot of surprises, especially in the A group.
Let us take a look at the situation a er rounds:
Who would have guessed that Wojtaszek would beat Carlsen
and Caruana in a very convincing way, or that Ivanchuk would
lead the tournament with a fantastic / . The play of Wesley
So and Ding Liren is also both good and stable. The young
Chinese players have been doing very well recently, even in
the best European tournaments.
These are the good surprises, now let us take a look at the
upsets:
Jobava has as usual been playing very attractive chess, but
he’s on a catastrophic score of . / !
The same goes to Aronian, who is probably having one of his
worst ever performances with . / . We should not forget that
Aronian has already won Wijk aan Zee times!
Caruana, who started to well, had a tough time losing to
Wojtaszek on Thursday.
Saric, Hou Yifan and Van Wely are also all having very hard
times, but this was more expected, as it is not easy to play
against players who are more than
points higher rated
than you.
In the B group things are also very mixed up, but the favorites
are still leading: Navara, Wei Yi (who is only -years old but
already has an ELO of
) and the Dutchman Erwin l’Ami are
all on . / .
A huge surprise was the loss of Jan Timman to Anne Haast.

Two best games of the past week

games continued with .Qb

Best rating:
Fabiano Caruana got into a suspicious position by
preparation, but some "invisible" mistakes of his strong
Chinese rival allowed him to nicely turn the game to his favor.
.d
Nf
.c g
Caruana would like to play the Gruenfeld
and Ding Liren chooses the g system against it.
.g c .Bg d .Nf
Bg
.O-O O-O .b
An ambitious
line where White tries to hold the tension in the center. The
main move is .cxd . This temporarily weakens the long
diagonal and Caruana directly makes use of it.
...dxc .bxc c
We are still following some theoretical
variation with hundreds of games with it.
.Bb
Qb
...Nc
Caruana follows the recent game of Gelfand. [The
other game continued with ...Bd Black prepares to
develop the knight to c and recapture with the bishop.
This seems to me to be a more accurate response than
Caruana’s choice. .Nd
Nc
If Black manages to finish the
development he might even get some advantage because of
the better pawn structure and the isolated pawn on c . .c
Qa
.Qc
Qxc
.Nxc
Rfc
The isolated c-pawn has the
advantage of having an opened b-file. White might put some
pressure on the b pawn, but it does not seem to be enough
to achieve an edge...
.Rab

followed
by a mass of exchanges and the game became very drawish,

.]
.Nxc bxc
.Nd !
This is the ideal development of the
knight. It is heading to b from where it might potentially
jump to c , a or d and at the same time it closes the b-file
against Black’s counterplay with Rb .
...Bf
This is the novelty. I am not sure if it was a prepared
one. [The previous game continued with ...Bg
.Nb !
Bxe
.Re
Bd
www.chess-newsletter.com
[ ...Rad was very natural, but it runs into the very strong
.Bc ! and suddenly it is not easy to deal with the Ba and
Na threats.; However ...Rfd ! seems to be stronger. The
point is that a er .Bc (It also prevents the deep idea of
White which he could execute in the game
.e ?
which does
not work now because a er
...Bxe
.Bxf
Bxg
.Bxg
Bxf
the f rook is not hanging...) ...a ! works!]
.c (I guess Ding Liren wanted to improve his own game
by playing
.Bd !
The idea is to keep the c square for the
knight. This is quite hard to find over the board, because Black
can save his extra pawn, but the activity turns out to be more
important. White seems to get an advantage everywhere...
...Qa
(On ...Qc
.Qc
Bf
.Be !
Qc
.Na !
If the c pawn falls, White gets an indisputable advantage
with such active pieces. ...Bd
.Rab !c White has more
than enough compensation for the pawn. Black cannot
really move with any of his pieces. The c and e pawns
are doomed.)
.Re !
Very strong computer moves. The
complications favor White in all the lines.

.Nb
Rac
Black wishes to push c ! which limits the
movement of the b knight.A erwards White could forget
about the Nd or Bd -Nc ideas. It also gets rid of the
weakness on c and fixes the white pawn on c , which might
potentially become a target like it happened in the game.
.e !
Very well played! Gaining space and pushing back the
black pieces.
...Be
A forced retreat. The pawn could not be taken
either way... [ ...Nxe ? drops a piece a er .Bxg

Bxg

and White ends up with an extra piece.]
.e ?
This is a very natural move, but it is wrong. It further
pushes back the black pieces, opens the diagonal of the g
bishop, closes the one on g , but somehow it turns out to be a
huge weakening of the pawn structure and this becomes the
most important positional factor. It is very hard to understand
and evaluate the plusses and minuses at first sight, but a
few moves later it all becomes clear. [The right move was
.Rb ! creating a highly unpleasant pin on the b-file with
which it is not easy to deal at all... ...Qa (On

is very strong and Black has no good way to protect the c
