Queen Endings: General Principles

Queen endings are perhaps not the most
popular subject among chess players. Possibly
because the task of calculating all the checks
appears so daunting. Indeed, a queen is a
powerful piece in almost all positions let alone
on an almost empty board! Yet, things really
aren't all that bad, especially not in queen
endings with several pawns on both sides. In
this article we will investigate some of the
general

principles

behind

those

queen

endings.
I will not make any observations on Q+pawn vs
Q endings. I refer the interested reader to John
Nunn's Secrets of Practical Chess (Gambit
2007; pp 148-153) which contains a very
practical

explanation

of

the

differences

between rook, knight, bishop and central
pawns

with

the

drawing/winning

zones

involved − the bishop pawn is the most
favourable one by the way.
We will examine the most important principles
by means of several examples. I have tried to
come up with a mix of classical and fairly
unknown fragments, aiming to please both
readers who are unfamiliar with the subject
and those who have a fair command of the
classical queen endings from endgame theory.
We will end our journey with two more complex
examples where most of the principles will
return.

Let us start with an elementary position, merely
to demonstrate that material is not of the
utmost importance in queen endings.
Black is five pawns up but after 1.a6 he has to
reconcile himself with a draw by perpetual
check as White's passed pawn is too far
advanced.

This example is taken from Batsford Chess
Endings, Speelman, Tisdall and Wade,
Batsford 1993 (p.414).
We will see that passed pawns are of the
prime importance in queen endings (only the
safety of the king is more important). Passed
pawns can be pushed forward to promote, they
can enable the stronger side to transfer into a
pawn ending, they can assist in the attack on
the enemy king, they can be assisted by either
queen or king towards the promotion square,
and they can be very useful for the king as a
hiding place for checks. Naturally, it is often
that one or more factors are combined.
In our next example White creates a passed
pawn and wins the game.

common escape for the weaker side in queen
endings). 1...cxb5 2.c6 Qc2 3.Qd5 [3.c7;

Black resigned.
(Maroczy - Bogoljubow, Dresden 1936)

By the way, Maroczy was a great specialist in
queen endings and you will encounter his
name again (and again) when you study queen
endings.

Our next fragment is taken from Maroczy -
Betheder, Hamburg 1930.
Here Maroczy is a passed pawn to the good
and in the realization of his advantage he
demonstrates a useful technique. It is Black to
move:

remember. Maroczy can leave his pawn

A final example with a far advanced passed
pawn.

So far the stronger side has been able to

White cannot escape a perpetual even though
he is allowed to promote to queen!

White to play can draw despite his deficit of
two pawns. 31.Qe8+ Kg7 32.Qe7+ Kg6
[32...Kg8 33.Qe8+] 33.Qxe6+ Kg5 34.Qh3!
[34.Qxe5+? Kh4-+; 34.Qe7+? Qf6-+] and now
the idea is that 34...h4? allows 35.Qf5 mate!
Therefore Black has to give up the g3−pawn
when the resulting position is a draw.
(analysis after − Bosch−Gustafsson, 2004)

Playing for mate is not an uncommon
occurrence in queen endings. Take a look at
the diagrammed position.

If you enjoy this type of exercise − there are
many more in Van Perlo's Endgame Tactics
(New In Chess 2006).

Where there is mate − there is also stalemate.
Again since the queen is so powerful there is
not only always the danger of mate but also of
stalemate. Always useful to remember when
you are the defender. Take a look at the next
position. Doesn't it look as if Black to move is
winning?

A technique well−worth remembering is giving
checks with the queen while approaching the
enemy king as if you are climbing a staircase.
The next game demonstrates how effective
this way of approaching can be.

Take a look at the diagrammed position from
Sokolov - Yusupov, Montpellier 1985.
Black has an obvious positional advantage. He
has a passed pawn and both his queen and
king are far more active than those of his
opponent.
In this example we will encounter a few
techniques we have already seen: hiding
behind the enemy pawns, a king march,
supporting your passed pawn, threatening to
transpose into a pawn ending, threatening the
enemy king.
Still, there is even one more new element to be
added: snatching the weak enemy pawns.
1...Qf6! 2.Qh7 Kf4! 3.Kd3? [3.Qd3 is met by
the centralizing 3...Qe5] 3...Qa6+ [3...Qe6 is
also strong.] 4.Kd2 Qa2+ 5.Ke1 Qa1+ 6.Ke2
Qb2+ 7.Kf1 Qc1+ 8.Ke2 If 8.Kg2 then
8...Qd2+ 9.Kg1 (9.Kf1 Kg3 10.Qc7+ Qf4+-+)
9...Kg3!? (9...d4; 9...Qd4+) 10.Qc7+ Kxh3
11.Qh7+ Kg3 12.Qc7+ Qf4 13.Qc3+ Kxg4
winning. 8...Qe3+ 9.Kd1 [9.Kf1 Kg3] 9...Kg3
and now White is helpless, for when his queen
moves from the h−file he will lose both his
pawns. The remaining moves were 10.Qh6 d4
11.Qh7 d3 12.Qc7+ Kg2 0-1

It is interesting that in Yusupov−Gerusel,
Moscow 1981, a fairly similar queen ending
arose (with colours reversed) which was also
won by Yusupov. See p.186 of Beliavsky and
Mikhalchishin's Winning Endgame Strategy
(Batsford 2000).
For the interested trainer/reader this book
contains many more practical examples of
queen endings (and all other endings).

background image

To recapitulate what we have seen so far:

-

Passed

pawns

are

often

more

important than material. (In queen
endings a queen can support a passed
pawn all by herself − as opposed to
say a rook)

-

Safety or vulnerability of the king can
be decisive (think of mate, stalemate
and perpetual check)

-

The stronger side can often transfer
into a pawn ending.

-

A king march is a useful technique (to
threaten mate, to support a passed
pawn, to win pawns or even to hide
behind enemy pawns)

-

Activity and piece cooperation are
vital.

I will end this article by two longer examples
where many of these issues return. First a
deservedly famous example with Maroczy
behind the white pieces.

1.Qh4! Note that White's king is a lot safer
than Black's and that White's queen is more
active. Material is equal though and there are
no passed pawns yet. 1...Kg7 2.Qg4+ Kf7

well aiming for activity. 5.Qe7+ Kg6 6.Qf8!

White's passed pawn is only two steps away
from promotion. The first question is whether
Black has a perpetual:
1...Qf3+ 2.Kg1 Qg4+ 3.Kf2 Qf4+ 4.Ke2 Qg4+!
The greedy 4...Qxh2+? allows the king to
escape, for example 5.Kf3 Qh3+ 6.Kf4 Qh2+
7.Kf5 Qh3+ 8.Ke5 Qg3+ 9.Ke6 and wins.
5.Ke3 Qg5+ The only move to draw. So as not
to allow the king to escape the corresponding
squares for the white king and the black queen
are: e3−g5, e2−g4 and e1-h4. Piket now
repeats moves before deciding (after the time
control at move 60) whether to make a final
winning attempt by giving up the d4−pawn.
6.Kf3 Qf5+ 7.Kg3 Qg5+ 8.Kh3 Qh5+ 9.Kg3
Qg5+ 10.Kh3 Qh5+ 11.Kg2 Qg4+ 12.Kf2
Qf4+ 13.Ke1 Qh4+ 14.Ke2 Qg4+ 15.Kd2!

16...Qf4+ Black can also draw by means of
16...c3 17.bxc3 Qxc3+ 18.Kd1 but he has to
display some accuracy: 18...Qd4+ 19.Ke2
Qg4+ 20.Ke3 d4+! 21.Kd3 Qf5+ 22.Kxd4 Qd5+
23.Ke3 Qg5+! and now White cannot use the
king march because of mate: 24.Ke4 Qg4+
25.Ke5 Qg5+ 26.Ke4= (26.Kd6?? Qd5#;
26.Ke6?? Qd5#). So interestingly after White
has given up pawn d4 Black can give up pawn
d5 to guarantee the draw. 17.Kc2 Qf5+
17...Qxh2+ 18.Kc3 d4+ 19.Kxc4 Qxb2 also
draws.(as does 19...Qc2+). 18.Kc3 Qd3+
19.Kb4 Qd4 More risky, but still sufficient is
19...c3 20.Kc5! cxb2 (20...c2? 21.Kd6+−)
21.Qe8+ Kc7 22.Qxc6+ Kd8 23.Qb6+ Ke8!
24.Qxb2 Qe3+!. 20.Ka5 [20.f7?? Qxb2+
