It is no longer typical to see top-level players

playing 

only

for the attack. In fact, Korchnoi

at the time of this game was one of the best

in the world, and his 

forte

was defense.

Many fine players would attack him ingen-

iously, only to break up on his rock-like for-

tifications. Still, World Champion Karpov

crushes him in only 27 moves with a mating

attack! In a classic manner against Black's

Sicilian Dragon defense (so named probably

because of the "tail" of control Black's bish-

op makes from g7 to a1), Karpov plays the

St. George attack, castling queenside and

prying open the h-file to slay the dragon.

14. Boris Spassky vs. Tigran Petrosian,

Moscow, 1969

Spassky won the world championship from

Petrosian in the match that produced this

game. In this English Opening that becomes

a Queen's Gambit, you'll see that once again

White gets a 

strong center

and quick 

devel-

opment

of his pieces. As early as 13. Rd1,

you can sense that Black is in danger. His

king has no piece defenders; his forces seem

passive while White's are aggressively coor-

dinated. As often happens in such situations,

White breaks through with a pawn push in

the center, in this case 15. d4-d5!. It clears

the board for White's more active forces.

Petrosian, one of the best defenders of all

time, tries repeatedly to trade queens, but

White wisely rebuffs these offers, which

would take much of the power off the board.

White's d-pawn becomes a star, advancing

all the way to the 7th rank. Because of this

queening threat, White is able to sacrifice his

queen for one of Black's defending rooks. In

the final position, it's hopeless for Black

because White will either promote his pawn

to a queen or capture whatever Black uses to

block on d8.

15. Robert Fischer vs. Reuben Fine,

New York, 1963

Nine years before winning the world cham-

pionship, Bobby Fischer played this Evan's

Gambit (a variation of the Giuoco Piano)

against his famous elder. Bobby sacrifices

two pawns in order to get his pieces out

quickly. Then he plays 14. h2-h4!, sacrific-

ing another pawn to force the Black queen

away from the g7-square. After that, Black's

king will be stuck in the center and in danger

of the h4-d8 diagonal. Bobby's final move,

17. Qg3!, forces Fine to resign, because he

must move his queen from the critical black

diagonal h4-d8. Even on 17. … Qxg3, White

ignores the capture of his own queen and

plays 18. Bf6 mate! 

16. Lajos Portisch vs. Johannessen,

Havana, 1966

During the first half of this game, a Queen's

Gambit Slav,  the great Hungarian grand-

master Lajos Portisch locks up the center

with a d4-e5 structure by move 14. This

gives him a "beachhead" on e5 and makes it

hard for Black to counterattack in the center,

which is the standard antidote for an attack

on the wing. The next stage starts with 16.

h4. Portisch announces his intention to

attack on the kingside. He refrains from

castling his own king into safety because he

knows it’s safe enough in the center, at least

for the time it will take him to break through

with his attack. When Black tries to trade off

pieces with 17. … Bxf3, Portisch sacrifices a

knight for an unstoppable attack with 18.

Bxh6 and then calmly moves his king to the

second rank to bring his other rook into the

game. His Rxh4 was another brilliant sacri-

fice that crushes any hope of defense. In the

final position, Black resigns because White

will simply play 26. Rxh6+, winning the

Black queen. If 26. … Qxh6, then White

plays 27. Qxh6+ and will mate on h7.

At any time during a game

when it is your move, you may

change the position on the board

by adding a piece or pieces,

removing one or more pieces, or

even changing any of the

pieces—for example, from a

knight to a queen. Obviously,

ENGLISH

7. Edward Lasker vs. 

George Thomas, London, 1910

This masterpiece, a Dutch Defense, features

a famous example of the king’s walk to

mate. Edward, an American distant cousin of

the great world champion Emmanuel Lasker,

gets his pieces activated against Black's

kingside while the English champion

Thomas 

develops

(gets his pieces off the

back rank and into play) too slowly. By 10.

Qh5, White is already threatening an all-out

blitzkrieg. His brilliant queen sacrifice 11.

Qxh7 is followed by a devastating 

discov-

ered double check

, 12. Nxf6++. Then

Black's king has to walk the plank, all the

way across the board to g1, the normal spot

for the White king! Here he breathes his last.

8. Wilhelm Steinitz vs. A. Mongredien,

London, 1862

This game starts out as a Center Counter

(also called Scandinavian Defense). Black

loses too much time developing his pieces,

while White gets his into play aggressively.

Indeed, White's army dominates the all-

important center of the board as well as the

king's side. This sets the stage for a mating

attack. White's two-move maneuver 13. Rf3

and 14. Rh3 is called a 

rook lift

, and is a typ-

ical attacking strategy. This rook then sacri-

fices itself on h7 in a way that allows Steinitz

to bring his other rook quickly into the fray.

White is a rook down, but all of his forces

take part in the assault, while the Black

queen's rook and bishop seem to be waiting

for the next game. They don't have long to

wait.

9. Aaron Nimzovich vs. 

S. Alapin, Riga, 1913

Another French Defense. In this one, the

great Latvian player and writer Nimzovich

(after whom the Nimzo-Indian Opening is

named—see page 6) plays an opponent who

wastes time stealing a pawn with 9. … Qxg2.

"Nimzo" plays a punishing 12. O-O-O!, sac-

rificing his knight. He finishes up with a

convincing queen sacrifice that forces

checkmate. 

10. Jose Capablanca vs. Herman Steiner,

Los  Angeles, 1933

The handsome Cuban World Champion Jose

Capablanca had a deceptively simple style.

Here we see him playing the old-fashioned

Four Knights' game and opening up his

opponent's kingside pawn protection by

move 11! His first rook sacrifice, 17. Rxf6!,

can't be refused and forces Black's king into

a deadly crossfire. With 23. Qxb7!, Capa

offers a second rook, which can't be taken

immediately because of 23. … Qxf6? 24.

Qb4 checkmate. But Black is forced to take

the rook a move later and mate follows on

the same square. 

11. Mikhail Botvinnik vs. Paul Keres,

The Hague, 1948

Botvinnik won the world championship a

record three times. His opponent here is pos-

sibly the strongest 20th-century chess player

who did not become world champion. The

opening is a Nimzo-Indian. White's 

doubled

pawns

are potentially a long-term weakness,

but in the short term they control a good

many all-important central squares. White

plays cleverly to keep a grip on the position

and breaks through on the queenside with his

pawn-push 17. c4-c5. This gives him a

chance to bring his queenside rook into

action. He swings it against the kingside,

sacrificing it on g7 to win. In the final posi-

tion, Black's king will be mated by the White

queen, supported by the bishop on c1. Where

did Black go wrong? Take a look at his

"unemployed" queen and rook on a8 and b8!

12. J. Banas vs. P. Lukacs, Trnava, 1986

In a Four Knights' Game, Black gets his king

into safety by castling and takes advantage

of White's awkward piece placement by sac-

rificing his knight with 9. … Nf3+. Then he

allows White to take his bishop on c5. But by

that time, White's king is surrounded. In the

final position, after 13. … Ng4, White's only

effective defender, his knight on e3, is forced

from its square, allowing … Qg2 mate.

13. Anatoly Karpov vs. 

Victor Kortchnoi, Moscow, 1974

Twentieth-century chess perfected defense.
