Here mate is achieved by winning
time to get the bishop aiming at g8:

I l:txh7+! 'iti>xh7 2 'iVhS+ 'iti>g8 3
.idS+. Note that if Black had a
bishop rather than a rook on f8 it
would already be mate. As it is he
can last three moves longer: 3 ... :n
4 'ii'xti+ 'ifi>h8 5 'ii'hS mate.

From a recent tournament game.
White played 1 fxeS, uncovering an
attack by the rook on the black
knight on f6. If he thought he was

doing well he was in for a rude
shock as l ... l:txh3+ 2 gxh3 'ifxh3
mate followed.

Despite being a rook down White
can win as follows: I l:td8+! when

I ... l:xd8 2 ..tc3+ mates in two
moves or l . . . 'ife8 2 .ig5!! and
Black has no way to prevent a fatal
check on f6. Finally if l...l:te8 2
.!:.xeS+ 'ifxe8 3 .ig5!! 'ii'd8 (he has
to stop 4 .if6) 4 .ixd8 .!:txd8 5
'ife5+ 'iti>g8 6 'ii'g5+ and White
picks up the rook and wins easily.
An incredible example of queen and
bishop co-ordination.

The bishop and queen
in a king hunt

We end with two further exam­
ples of the queen and bishop acting
against different squares in order to
achieve mate. In both examples the
enemy king has been driven out of
his defences.

Campos Moreno - Adams
Cala Galdana 2001

Here Adams played the crafty
26 .• .'ifc7 when White should have
adopted a defensive stance with 27
1i'd2, for example 27 ... 'ifb6+ 28
'ife3. But he failed to see the danger
to his king and played the aggress­
ive 27 lLlaS? when 27 ... 1i'a7+! was
fatal: 28 �g3. If 28 �e1 1i'e3 mate
28 .. Jlg8+ 29 �h3 i.c8+! and
White resigned. White has his own
threat of 'ifxd6+ �d8; 1i'd8 mate,
so Black has to do everything with
check.

There are two variations:
30 �h4 1i'f2+ 3 1 g3 1i'xh2 mate

or if 3 1 �hS llgS+ 32 �6 1Wh4
mate.

30 g4 i.xg4+! 3 1 fxg4 (or 3 1
�g3 i.e6+ 32 �h4 1i'f2+ 33 �hS
1i'xh2 mate) 3 1 . ..1i'e3+ 32 �h4 (or
32 �g2 l:lxg4+ 33 �h1 1i'f3 mate)
32 ... 'iff2+ 33 �h3 1i'f3+ 34 �h4
1Vxg4 mate.

Kasparov - Ponomariov
Linares 2002

a b c d e f g h

a b c d e f g h

An epic battle from the
penultimate round of the great
Linares 2002 tournament. For the
frrst time Ruslan Ponomariov was
playing in a world elite tournament
and he was lying equal first with
Kasparov. At least until he fell into
the bind in the position above.

Black's defences along the d file
are holding firm, but Kasparov
cleverly exploited an undefended
diagonal on the kingside with 36
i.e2! rerouting the bishop to hS.
Already there is the threat of 37

Further evidence that Legall's
mate has evolved into a strong
tactical device. Here Short played
14 lbxe5! Black now loses a piece
after I4 .. . .i.xdi IS lbd7+ c;i{g8 I6
lbxf6+ gxf6 I7 �xdl . If instead
14 . . . .i.xe3 I S lbd7+ wins just the
same. So he had to make do with
14 ... dxe5 but eventually lost after
15 'ihg4.

This position is from another
game by Capablanea, who forced
mate as follows:

l. .. lbtl+ 2 ¢'gl

If 2 :X£2 l:e 1+ 3 l:fl llxfl mate.
2 ..• lbh3+ 3 ¢'hi
It seems as though the game will

end in repetition after 3 ... lbf2+ 4
�gi but. . .

3 .•• llg2! 4 .i.xg4 llgl+! 5 l:xgl
ibn mate.

2l ... llxa2! 22 �xa2 'iVa5+ 23
�b3 .i.xe5

Now 24 dxcS 'iVa4 is mate, but
my opponent confidently played 24
llal attacking the queen. Evidently
he thought this refuted the attack,
but after 24 ... lbb6! he resigned. It
is mate in one with 25 llxa5 .i.c4 or
in two with 2S .i.d3 .i.a4+ 26 �a2
.i.c2.
