Miguel Illescas:

Backward pawn on c7

When white takes c4xd5 and black
recaptures with e6xd5 in the queens gambit,
we reach the well known Karlsbad structure,
where black usually plays c7–c6. But
sometimes, black delays or is not able to
play c6, and white manages to advance his b
pawn to b5, leaving the c7 pawn backwards.
In this article we will have a look at this type
of positions, which usually are in white's
favour. Let's start with a fantastic game by
Magnus Carlsen, where the World champion
shows a deep understanding of this type of
position.

Carlsen : Aronian (2015)

With this check black is forced to develop
the knight to c6, a square where black would
like to place the c7 pawn, in order to
neutralize white's activity on the c line and
not less important, to give proper support to
the central pawn on d5.
8...Nc6 9.e3 0–0 10.Be2
If 10.Bd3 Bg4 is annoying.
10...Be6 11.0–0

Open ing phase is over and both sides need
to imagine a long term plan.
11...a6
A typical move, to control b5, thus the dark
squares bishop may land on d6 without
being annoyed by the white's knight.
12.Rfc1
Bringing this rook, White shows his
intention to concentrate his efforts on the
queenside.
12...Bd6 13.Qd1

The job has been done and the queen
retreats, allowing the maneouvre Nc3–a4–
c5.
13.Qb3?! Ne7, when the pawn b7 is tabu and
the white queen is badly placed.
13...Ne7
A standard move, allowing black to play c6
if needed, and looking for better prospects
for the knight. I like howewer the way black
played in L. Portisch : Sosonko (Wijk aan
Zee 1975): 13...Rae8!? 14.Na4 Nd8! 15.Nc5
Bc8! and black hold to a draw in a long
battle.
14.a3!?
Simple chess by Magnus, who prepares b2–
b4. A typical plan was seen in Taimanov :
Kotov (Zürich 1953): 14.Na4 b6 15.Nc3
Rfd8 16.Qf1 c6 17.Na4 Rdb8 18.Rc3 a5

Bd6 27.Rb1 b5? 28.Nc5 Bc5 29.Rc5 and

white got the advantage and won the game
20 moves later.
14...Rfd8
I don't like this move, since I have the
feeling that this rook belongs to e8.
The game Jobava : Efimenko (Rijeka 2010),
continued with a more active play by black,
which deserves attention. 14...c5!? 15.dc5
Bc5 16.Na4 (16.Nd5 Bd5 17.Rc5 Qb2; 16.e4
Ba7! 17.ed5 Rfd8 and black is fine) 16...Ba7
17.b4 d4 18.Nd4 Rad8 19.Qf1 Bd4 20.ed4
Nf5 21.Nc5 and a draw was agreed.
15.b4
Black lost the battle on the queenside and
needs to create play on the other flank.
15...Nc8?!
Too optimistic. Maybe Aronian thought he
could jump to c4, but Magnus will not allow
it. More logical looks 15...Ng6 16.Na4 b6
17.Nb2 h5 18.Nd3 h4, with some
counterplay.
16.Na4 b6
Black cannot allow the enemy knight to
jump to c5, but now c6 and a6 become
vulnerable.
17.Nb2! Ne7
It si clear that black's plan has failed.
18.Nd3 Ng6

19.a4!
Excellent positional chess. The threat is a4–
a5, and black would be forced to close with
b6–b5, leaving a6 too weak.
19...a5 20.b5

We reach a standard position. The weakness
on c7 is definetely fixed, and the pawn on d5
will need permanent piece support.
20...Re8 21.Rc3
A typical idea: white doubles on the c line
increasing the pressure. Black will need to
keep the bishop alive on d6 at all cost, and
the exchange sacrifice on c7 will have to be
watched all the time.
21...Bf5 22.Rac1
White may jump to e5 at any moment.

after 23...Bg4! 24.Nd2? black has 24...Be2
25.Qe2 Qd4!
23...Rd7 24.g3
Killing the activity of the black pieces.]
24...Nf8 25.Bg4!
Standard play: white eliminates the enemy
pair of bishops, and makes even weaker c6
and d5.
25...Nh7
25...Ne6 covering c7 was another idea.
26.Bf5 Qf5

27.Qf3!
Black queen is too active.
27...Qg5?!
Magnus said that black should avoid the
queen's exchange, but I am not so sure.
White's queen will be very dominant on f3.
After 27...Qf3 28.Nf3 g5! 29.Nfe5 Rde7
white is better, but black remains solid.
28.h4 Qe7 29.Rc6!
The rook will prove very powerful here.
29...Nf6 30.Nf4! g6?
Aronian prevents Nh5 but weakens his
kingside with this move. It was not good for
black 30...Bf4 31.Qf4 Rc8 32.Rb6; But it
was possible to stay passive. 30...Ba3
31.R1c2 Bd6 White is better. Magnus
pointed a possible plan involving the transfer
of the knight from d2 to c3.

Carlsen had to foresee the following
variation: 31...g5 32.Nd5! Nd5 33.Qd5 and
white is winning: 33...Ba3 (If 33...Bg3
34.Qf5 Bd6 35.Nc4 Qe6 36.Nd6 Rd6 37.Qe6
Rde6 38.Rc7) 34.Qf5! Bc1 35.Rh6 with a

white knight landing on g5 or e5. 33...Ng7

Qg5 37.Kf1 Rf8 38.Nf3 Qg4 39.Ke2 Rdf7
40.Rc7! etc.
36.Nc4! Rf8?
The last mistake in a difficult position.
36...Qd8! was the only move to stay alive.
After 37.Nd6! (Also good is 37.f4!; But not
37.Ne5? Be5 38.Qg6? Kh8 39.Qh6? Rh7)
37...cd6 38.Qg4 white is much better.

Anand : Ljubojevic

This game was played at a rapid tournament.
That is why it is even more impressive to see
Anand's technique.

connected with the moves 11...c6, planning
a7–a5 or the inmediate 11...c5.

White plans to take on a6 and jump to b5 so
black's answer is kind of forced.
16...a5
This wing is closed, but we reach the typical
position with an ugly backward pawn on c7.
17.Bf1!
Anand wisely prepares the transfer of his
bishop to g2, from where it will make
pressure on the weak pawn on d5.
17...Rad8 18.g3 h5!?
Ljubo will try to create some play on the
kingside.
19.Bg2 h4 20.Ne2

the c file.

Black had a unique opportunitie to create
real counterchances with 32...Qd7! 33.a4 g5!
34.Ne2 Re8 and white has somehow lost
control of the kingside.
33.Qd1 Reh8 34.Nd3

Topalov : Sasikiran

In this game we will see the importance for

the opponent to do his plan.

Be7 and black is fine.
11.b5!? Ne4?!
Black is paying no attention to the
opponent's idea.
11...a6! was probably necessary: 12.Qc2 Be7
