15. Bc2 Qe7 16. d5 {White had done better to mark time also;
the text move would have a meaning only if it were introducing
an attack against the Q side, (c4, and b4). But he intends to
operate on the K wing, and for this d5, is a bad preparation.}

plan of Ng1, and f4.} 18. Ng1 g5 19. g3 Ng6 20. Qd1 Bg7
21. Qf3 a5 {Again preventive play. This time the possibility
of c4, and b4, is to be anticipated.} 22. Ne2 Bb5 23. a4 Bd7
{It is achieved; the White Q side has lost all momentum and
the action just mentioned, to be initiated by c4, and b4, is a
thing of the past.} 24. Rh1 {With this move White plans to
break through eventually with h4, e.g. : 24...b6 25 h4 gxh4 26
gxh4 Nxh4 27 Qh5 f5 28 Kg1, etc. But Black discovers a move,
which not only has a high preventive value, but which also has
the attribute of driving the opponent into quick action.} Qe8
{! The threat is ...Qc8; e.g. ...Qc8, h4 ...Bg4, winning a
knight. White, therefore, has no further time for preparations
and opens the battle for a breakthrough.} 25. h4 Qc8

29. Qf1 {The breakthrough looks like it is succeeding, for if
now ...Bd7, then g4 followed by Qxh3 with a winning attack.}
f5 {The counter-stroke, long since prepared, which decides the
battle for Black.} 30. fxg4 fxe4 31. Qxh3 exd3 {Only now can
the full effect of 28...h3 be discerned. By this move the
white queen was forced from g2 to f1 into the range of the
Black rook.} 32. Bxh6 Rh8 {This game is noteworthy on account
of the comprehensive prophylaxis employed; preventive measures
were taken against c4 and b4 as well as against f4 and later
on h4. A few words about the charachteristics of the
preventive moves selected ; the waiting policy by 10...h6 is
typical of this style of play, for waiting moves form the
beginning of all prophylactic manouvers. The fact that the
preventive move 24 ...Qe8 contains a threat at the same time
by no means detracts from its purity in a prophylaxis, in
which part of the plan is to drive the opponent to acceerated
action.} 0-1

5.Nxe5 {An innovation first tried on this ocassion.} Qe7
{Best; unfavorable would be 5...Nxe5 6 dxe5 Ne4 on account of
7 Qg4.} 6.Nxc6 {If the sacrifice of a pawn does not appeal,
the following line of play, recommended by Dr. Krause, will
serve : 6 Qd3 Nxe5 7 dxe5 Qxe5 8 Bd2.} Qxe4 7.Be2 Qxc6 8.O-O
Bxc3 9.bxc3 Qxc3 10.Rb1 O-O 11.d5 {With this move the White
bishops become jointly active.} Qe5 12.c4 {At this stage the
following continuation is also playable : 12 d6 Qxd6 13 Qxd6
cxd6 14 Ba3, etc.} Re8 13.Bd3 d6 14.Bb2 Qh5 15.Qd2 Ne4 {It is
clear that black under-estimates the hostile bishops or he
would have played 15...Ng4; if then 16 h3 Ne5 and Black
threatens to benefit materially (Nxd3) and theoretacally (f6),
closing the long diagonal) The bishops are made innocuous. But
then the prophylactic style appears only to the few.} 16.Rbe1
Bf5 17.Qf4 Qg6 18.Re3 {the violent move 18 g4 would be refuted
by 18...Bxg4 etc.} Kf8 {In order to hold the rook more
securely covered.} 19.h3 {Not 19 Rfe1 because of ...Ng3
etc. The move in the text is preliminary to the decisive
attack by Rf3 which now would fail on account of ...Bg4.} h5
20.Rf3 Bd7 21.Re1 {The impression is gained that two bishops
have to be taken seriously. But prophylactic measures based on
the elimination - in fact or in effect - of one of the bishops
(see note to move 15) do appear to present a notable
specific.} 1-0

d4 is the "base", and as such should be protected as
thoroughly as possible. Be2 "protects" more thoroughly than
Bd3.} Bd7 {A very plausible move. Since White still delays
...dxc5, Black intends his hand with ...Rc8. the right course
was 6...csd4 7 cxd4 and thus to pass into quite other
channels. See Paulsen-Tarrash, 1888 and Nimzowitsch-Tarrasch,
1912.} 7.dxc5 {!!} Bxc5 8.O-O f6 {Black swells in triumph and
throws himself hungrily on the last remaining menber of the
once so proud chain-family, top destroy him. His war cry is
"Room for the e-pawn!" But it happens quite otherwise.} 9.b4
{In order to be able to provide his e5 with an enduring
defence. 9 Qe2 would also have been a defence, but no enduring
one, for there would follow 9...fxe5 10 Nxe5 Nxe5 11 Qxe5 Nf6
and the blockading queen at e5 will be easily driven away.}
Be7 10.Bf4 fxe5 {Again we have the exchange operation which we
have so often discussed; this time however, it is not really
justified, for the new blockader, the bishop at e5, proves to
be a stout fellow.} 11.Nxe5 Nxe5 12.Bxe5 Nf6 {For the

it is true has won a pawn, but black has overcome the
blockade, and now stands ready to march in the center. White
should lose.} O-O 14.Nf3 {! The blockading forces are to be
reinforced by the knight.} Bd6 {14...Bb5 would yield little

15.Qe2 {The manouver 15 Bd4 Qc7 16 Qe2 might be considered
with the intention of following with 17 Ne5. However, this
plan to widen the blockading ring is impracticable, for, after
16 Qe2 Ng4!! 17 h3 e5!, the Black pawns assert themselves
whatever counterchances be taken.} Rac8 16.Bd4 Qc7 17.Ne5 {The
immobility of the e-pawn is now greater than ever. White has
utilized his resources very economically. The possibility of a
successful occupation of the points d4, e5, hung on a hair, on
taking advantage of the terrain (the points d4, e5, c2 and

1. e4 { Notes by Raymond Keene. With two bishops for two
knights, and a central pawn majority, Black probably felt
confident in the outcome of this game. But Nimzowitsch proves
that the opposing centre is a liability because the squares in
front of it are weak, inviting invasion by blockading
knights. The bishops, locked behind the pawns, are never given
a chance. Not strictly true! Nimzowitsch inadvertently allows
the bishops to escape, but then proceeds to dominate them with
his knights on an open board.} e6 2. d4 d5 3. e5 c5 4. c3 Nc6

position, since the the enemy Queen file "bites on granite"
(the protected P at d3). This solidity, however, also finds
expression in the fact that White's e-Pawn can never be
troubled by an advance of Black's d-Pawn; in other words, the
center cannot be opened.} Bg4 {The pin.} 8. h3 Bh5 9. Bg5

bring his Kt to f5 via c4 and e3; on the other hand he
proposes to prevent the embarrasing move ...c4 for as long as
possible without the aid of c4, since this move would leave
the output position in the Queen file (at d4) unguarded.} Qe7

a worthy reception of the enemy Queen at d4, for which point
she is striving. Observr how the first player has succeeded in
combining the defence of the center with his plans for a
King-side attack.} Qd6 28. Qc1 Qd4 {?} 29. Nd5 {! Traps the
Queen. This "trap" was everywhere applauded. That it was
subordinate to the strategic ends which I had set myself in
this game was taken into consideration by no one. The aim of
my strategy was, however, to prevent a breakthrough or any
manouvering in the center and to make possible the ultimate
advance g5 with the attack.} Rxd5 30. c3 Qxd3 31. exd5 {cxd5

which the knight at f4 has played. As a blockader he was
strongly posted and excellently supported (by the bishop at
h2). Again he had a crippling affect on Black's bishop at g7
and rook at h6, etc. Further, his "threat effect" was
considerable, particularly on the points d5 and e6. (The
mobility of White's e-pawn affords a piquant antithesis to the
immobility of Black's pawn at f5.) And lastly, his elasticity
was striking, for he could composedly go on his travels,
leaving the bishop to take his place.} 1-0

which appears my idea of a pawn sacrifice in the opening, not
to obtain an attack, but merely, with gain of a tempo, to
overprotect a strategical point with a view to cramping the
enemy forces.} e6 2. d4 d5 3. e5 c5 4. Qg4 {My innovation.}

careless when, if ever, he recovers it provided his pawn at e5
is maintained as an instrument to cramp Black's game. There is
no idea of attack in 9 h4, its object is solely to pave the
way to the removal of some of the pressure on the p at e5. The
pawn sacrifice comes with the category of sacrifice for the
sake of blockade.} Bd7 {...Bc5 was essaential here so as to
leave the f8 square free for the knight to retreat after h5.}

would have had some difficulties to contend with. The text

1. Nf3 {Notes by Nimzowitsch} f5 2. b3 b6 3. Bb2 Bb7 4. g3
Bxf3 {This exchange appears to be unfavorable, for as will
soon be seen, the Black pawn-formation will lack mobility.}
5. exf3 e6 6. f4 Nf6 7. Bg2 c6 8. O-O Be7 9. Qe2 O-O {The
White bishops are strongly posted but have, as yet, little
effect.} 10. Na3 {This knight is placed into the service of
the bishops. In the sequel it will not only reconnoitre the
ground but lure on thre Black pawns. Its most important
function, however, will reveal itself only on the 13th move.}
a5 {The only way to develop the knight, ...b5 fails against
Nxb5.} 11. Nc4 a4 12. Bd4 b5 13. Ne5 {If, in the course of
play, I had looked upon this knight as an outpost on the K
file, there would have been no reason why I should publish
this game here; but I saw in this Kt nothing but a diagonal
outpost : a vague, up to now undefined diagonal effect
acquires, through posting the knight on e5, a definite aspect
with clear-cut objects of attack, in other words : the
diagonal action now obtains.} Nd5 {After 13...Na6 the
continuation would be, not sacrifices at c6, but simple
development by 14.Rfe1 followed by c4.} c4 bxc4 15. bxc4 Nb4
{With the understandable desire to take advantage of the
knights short stay in the central position (d5) according to
the motto "via the center into enemy land". The scheme,
however, proves disastrous. But with passive play (...Nc7) an
ultimate break-through by d4-d5 would have been decisive.}
16. Bc3 a3 17. d4 N8a6 18. Rab1 Rb8 19. c5 {Normally d5 is the
proper course, but the knights unfortunate position is more
easily exploited by the text-move.} Bf6 20. Rb3 Bxe5 21. fxe5

insecure, is inadmissible, we have emphasized already more
than once.} 9. Be2 {Here 9 c4 was indicated, e.g. : 9 c4 Bb4

now a clear line of fire to the enemy king's wing. Impressed
by this the second player is inclined to underestimate the
fact that the d-pawn is now passed; in fact to overlook it
altogether. And indeed what possible road could this most
carefully blockaded passed pawn play? Why, a reserve blockader
is already atationed at d7! But things turn out quite
otherwise.} 16.Re1 Qd8 17.Bb1 {This attack leads to the
instructive results that the blockading pieces, the bishop at
d6 and knight at d7 are either cut off or killed off.} Re8

the passed pawn is indirectly protected.} Kh8 {Not 25...B or
Rxd5 because of 26 Re1 and 27 Ne7+ etc.} 26.Re1 Qf8 {! If
26...Qg8, the passed pawn would have come into his own in a
most interesting manner; namely as follows : 27 Ne7 Nxe7 28
Rxe7 (7th rank) Qxg3+ 29 Kxg3 Rg8+ 30 Kf2 Rg7. Apparently the
7th rank is now neutralized, but the passed pawn has something
to say to that. 32 d6 Rxe7 32 dxe7 Bc6 33 Be4 Be8 34 f5! Kg7
35 Bd5 and now the pawn at e7 is unassailable. 35... Kh6 36

Kd5, and Bc6, and the blockader must die.} 27.d6 {!} Rd7 {Why
not ...Bc8, would not this have led to the winning of the
passed pawn? The answer is no, for the continuation would be
28 Ne7 (By his p-d6 White has provided an outpost atation at
e7) 28...Qh6+ (best) 29 Kg1 Nxf4 and now 30 Nxc8 Rxc8 31 d7

retreat ...Rd8. But in this case the 7th rank will be left
without protection and White wins by Re7. Note that the

regarded as a direct consequence of the passed pawn's
advance.} Rxd6 {A desperate expedient. If 28...Rf7 then 29 d7

has in mind the manoeuvre Nh1-f2-h3-g5, in conjunction with
Qh5, as a method of assaulting the position of Black's
king. When I first read My System I was so impressed by this
game that I deliberately created situations in my next few
games where the move Ng3-h1 was possible, in the belief that
this mystical retreat would somehow result in a miraculous
increase of energy in my position, irrespective of whatever
else may have been happening on the board at the time.}

of this type requires courage - and faith in the inner meaning
of the blockade. The move gives up a tempo (non-development of
a piece) and crates a hole on d5, all this to prevent White's
d4, and so to obstruct his opponent.} 4. Bc4 d6 5. h3 Be6

short of effective moves.} 8. Nd5 {With the object of

this can be achieved only with the help of sacrifices in
material or position.} Nf6 {Mow d5 is under fire.} 9. Nh4

Bxd5 11. Nf5 {The sacrificial operation mentioned in the note
to move 8. White wins back his pawn but remains with doubled
pawns; the sacrifice therefore turns out to be positional. He
had the option of sacrifice in material by 11 Bxd5 Bxh4 12 f4
with attacking chances. All things being equal, either
sacrifice should suffice to secure a draw.} Bxc4 12. dxc4 g6

1. c4 {Notes by Nimzowitsch In this game Black does not
succeed in getting the adverse double complex to advance
(White stays "put") and therefore the symptons of the malady
are not clearly distinguishable. there is compensation,
however, in the observation of atypical secondary sympton, the
helplessness of the White pieces. These pieces would, in the
ordinary way, be quite ready to attack, but the enthusiasm for
an attack is damped by the consciousness that the cO-Operation
of the "pawn-party" cannot altogether be depended upon. As the
incriminated body of pawns is unreliable also in a defensive
sense, (for there always is a danger of its being rolled up by
...c6 and ...d5) the undecided attitude of the pieces (10 Qc2
11 Qd2) is sufficiently explained. And so the hidden weakness
of the pawns is projected to a plane where it is clearly
noticeable by the learner, and the study of the game is made
highly valuable.} e5 2. Nc3 Nf6 3. Nf3 Nc6 4. e4 Bb4 5. d3 d6
6. g3 Bg4 7. Be2 {This is not as inconsistent as it may
appear, for g3 was primarily intended to cover a knight move
to h4 and on the other hand Bg2 would permit ...Nd4.} h6
8. Be3 Bxc3+ 9. bxc3 Qd7 10. Qc2 {White realizes that the
mobility of his center pawns is small as d4 and still more so
d5, would paralyse him on account of the weakness of
c5. Therefore he seeks to adapt the movement of his pieces to
his modest circumstances in space. In this sense he could also
have played 10 Nd2 (to effect a strategic retreat with f3)
e.g., 10 Nd2 Bxe2 11 Qxe2 Ng4 12 f3 Nxe3 13 Qxe3 O-O 14 O-O
with an approximately even position. But 10 Qd2 must be looked
upon as a misuse of the modest space available, for that
square should remain open and the queen, in any event, would
be better placed at c2 with an eye on a4 and the eventual
threat of ...d5 in view. After 10 Qd2 we recommend 10...Na5 11
Qc2 O-O followed by ...Rfe8, ...c6, and ...d5, and Black has
the better position.} O-O {Here too we should prefer ...Na5
(d4? ...Nxc4)} 11. Qd2 {Now in order as Black's castled
positionis in jeopardy.} Nh7 {In order to play ...f5, but this
proves impractical, and the only result is a decentralised
knight on h7.}12. h3 {Nh4 would also have been sufficient.}
Bxh3 {This loses a piece. black had only reckoned with 13 Bxh6
which by the way would also have been strong, e.g., 13 Bxh6
Bg2 14 Rh2 Bxf3 15 Bxf3 gxh6 16 Qxh6 f6 17 Bg4.} 13. Ng1 Bg4

line was strongly recommended in Chess Praxis where
Nimzowitsch writes of 'the triumph of the bizarre and ugly
move' (Siegeszug being translated as 'triumph', but it
actually means triumph in the sense of a Roman triumph --
perhaps 'victory march' is a better translation). This game is
an amusing example of the victory march in progress. Note that
this move seems to plan the exchange of bishop for knight at
great speed. } 3...Qc7 {Modern theory centres around 3...g6,

1. e4 {Notes by Nimzowitsch. This game is an example of
overprotection.} e6 2. g3 {Tartakower's interesting
suggestion.} d5 3. Nc3 {More obvious was Bg2 with d3. At c3
the knight is subject to molestation.} Nc6 4. exd5 {d3 and Bg2
would still have been better.} exd5 5. d4 Bf5 6. a3 Qd7 7. Bg2
O-O-O {The d-pawn is covered indirectly, e.g. : 8 Nxd5 Qe6+ 9
Ne3 Nxd4; or 8 Bxd5 Nf6 9 Bxc6 Qxc6 with a superior attacking
game.} 8. Nge2 Nce7 {The following are the component parts of
the strange-looking line of play : (1) e4 clearly must be
looked upon as a strategically important point (= an outpost
on the e-file), (2) consequently the d-pawn which supports
this point is valuable. Over-protection of this valuable pawn
is therefore in keeping with our stratagem of
over-protection. The question arises (3) will the Kt which is
to occupy e4 be able to maintain itself there? It must be
recognized already that such is the case (compare Black's 12th
move). Much weaker at this stage would be 8...Nf6 because of 9
Bg5.} 9. Nf4 Nf6 {Now Bg5 can no longer be played.} 10. h3 h5
11. Nd3 Ne4 12. Be3 {Now White threatens exchanges followed by
Nc5. The prospects of the knight on outpost duty appear to
have shrunk alarmingly, in fact, the whole system 8...Nce7
appears to be practically refuted. But No, it is not so.} Nxc3

difficulty is not so much the problem of the pawn-center as
the fact that White's centralized bishop keeps the g-pawn

merely a developing but also a waiting move. for Black is in
all circumstances compelled to create a new weakness if he
wishes to arrive at a reasonable development, and White van
afford to wait until Black decides to play ...a6 or
...b6. Therefore 13 O-O, which looks like a developing move,
was in a reality a tentative waiting move} b6 {The alternative
13...a6 also had its drawbacks. Entirely bad, however, would

of creating a weakness by ...a6 or ...b6 a Steinitz would no
doubt have tried 13...Be7, e.g. : 14 Nd5 Bd8 15 c4 O-O 16 Bc3

Black's game could have been held, as shown by 9...Nc5 and
perhaps later even with 13...Be7 and 14...Bd8 (though this
required the defensive powers of a Steinitz). Also 10...Ne5
possessed strength. Giving up the center is not necessarily a
catastrophe.} 1-0

1.e4 {AN INGENIOUS EXAMPLE OF MY SYSTEM by Aaron Nimzowitsch -
Anderssen started the sacrificial style, Morphy and Gruenfeld
the pure attacking style, Steinitz the positional style,
Tarrasch the scientific style, Lasker the style of styles,
Capablanca the mechanical style, Alekhine a style as brilliant
as sunlight. But it is a generally known fact that originality
and modernism were introduced by me as my own personal
inventions and enthusiastically imitated (without being fully
understood) by the whole world of chess. For the ridiculously
small sum of ten marks, the reader can confirm all this in my
monumental work, My System, published by B. Kagan. Before my
time, chess was so naive and undistinguished! One or two
brutal opening moves, each one involving a vulgar, obvious
threat, a common, banal sacrifice, a painfully elementary,
bestially raw checkmate - such, more or less, was the course
of chess games before my heyday set in. Then I appeared on the
scene and the chess world paid heed. The hegemony of matter
was shattered at a stroke and the era of the spiritual
began. Under my creative guidance, the chessmen, hitherto
nothing but highwaymen, pirates and butcher boys, became
sensitive artists and subtle instruments of immeasurable
profundity. But why waste words!--accompany me, dear reader to
the dizzy heights of the following game.} e6 2.h4 $1 {My very
oldest and latest thought in this opening. To the chess addict
nurtured on spineless convention, this move comes like a slap
in the face--but calm down, dear reader; after all, you cannot
be expected to understand such moves. (Forgive me - it is not
your fault, until now no one has opened your eyes and ears.)
Wait just a little while, and there will pass before you a
miracle of overprotection of more than earthly beauty. (I
assume that I rightly surmise that you are quite familiar with
my great theory of overprotection.)} 2...d5 { Black of course
has no suspicion of What is coming and continues serenely in
classical style. } 3.e5 $1 {A move of elemental delicacy. (We
detest, as a matter of principle, such words as "power" and
"strength"; in the first place, such banal expressions make us
uncomfortable; and, in the second place, we like even less the
brutalizing tendency which such words imply.) Wherein lies the
beauty of 3.e5? Why is this move so strong? The answer is as
simple as it is astonishing. The move is strong because it is
weak! Weak, that is, only in the traditional sense! In
reality, that is to say, it is not the move but the Pawn on e5
that is weak--a tremendous difference! In former times, it is
true, it was customary to reject any move which created a
weakness. Today, thanks to me, this view is obsolete. For,
look, my dear reader, the fact that the Pawn on e5 is weak
obliges White to protect the Pawn more and more until at last
the state of overprotection arises as it were of itself. But,
as we have seen (cf. My System), overprotection is practically
equivalent to victory. Hence it follows automatically that the
"weak" move, 3.e5, is a certain road to triumph. The rest is
more or less a matter of technique. } 3...c5 { All according
to a famous precedent.} 4.d4 {Here it is quite clear that it
is more profitable for White first to provoke c5 and then play
d4, rather than the other way round, which is the customary
course. For, if White first plays d4, there follows c5 and
White's d-pawn is under attack. But my clever transposition of
moves changes the situation completely. For now Black's c-pawn
is suddenly attacked by White's d-pawn!} 4...cxd4 {What else
can Black do?} 5.h5 $1 {All very clever, original and
decisive! Of course the ordinary run of people who envy my
every spark of genius but cannot follow my line of reasoning
for even three paces, outdo themselves in sneering at me with
the poison-dripping epithet, "bizarre." The text move creates
confusion in the whole Black army and prepares for the
annihilating invasion by the Queen 18 moves later.} 5...Qb6
{Naturally not 5...Nc6 6 Bb5! etc. Why should Black play the
French Defence only to allow the Ruy Lopez Bishop move after
all?!} 6.h6 $1 {An avaricious dullard would never hit on this
deeply conceived Pawn sacrifice.} 6...Nxh6 {After 6...gxh6,
White has an even more comfortable game.} 7.Qh5 $1 {The reason
for this becomes clear after next move.} 7...g6 {Black
threatens to begin a successful siege of the weakling at e5
with Bg7. But White forestalls this.} 8.Qh2 $1 {To every
fair-minded observer, this move must come as a revelation! All
the previous manoeuvres now become clear! White has completed
his development brilliantly and proceeds to overprotect
e5. Against this, Black is helpless.} 8...Nf5 9.Bd3 {Note the
splendid cooperation of White's forces: while the e-pawn and
the King Bishop completely blockade Black's position, the
development of the overprotective forces takes place behind
the broad backs of these sturdy blockaders.} 9...Nc6 10.Nf3
{As a rule this is a routine move. But here it is strikingly
original and as such occupies a place in the treasury of my
intellectual property.} 10...h5 {Old stuff!} 11.b3 {A deep
trap, as will soon become apparent!} 11...Bg7 {How Black must
have rejoiced when he anticipated his formidable opponent in
the occupation of the long diagonal. But...} 12.Bf4 $1 {...how
bitterly disappointed he must have been to realize that 11.b3
had only been a trap and Bb2 had not been intended at all. The
position of Black's Bishop at g7 is now quite
pointless. 11...Be7 would have been relatively better.}
12...Bd7 13.Nbd2 Rc8 {Black no longer has any good moves!}
14.Ke2 $1 {Again, an extraordinarily deep move. White sees
through Black's plans, and in addition he prepares a
particularly powerful continuation of his strategy of
overprotection.} 14...Nb4 {Just what White was waiting for.}
15.Ne1 $1 {This was the point of his previous move! Black is
now forced to exchange off the attacking Bishop at d3. But,
with that, even White's King Knight enters the fray with
fearful effect at d3, while the square f3 becomes available to
the Queen Knight. Surely a grandiose piece of strategy. The
fact is that I'm a marvellous player, even if the whole chess
world bursts with envy.} 15...Nxd3 16.Nxd3 $1 {Naturally not
16 cxd3? which would have been quite inconsistent. The Pawn on
c2 is unimportant, and Black only wastes precious time by
capturing it.} 16...Rxc2 17.Rae1 $1 {White continues his
overprotection without much ado.} 17...a5 {This counterattack
has no punch. Black would naturally like to get a passed Pawn
plus a Rook on the seventh, but it is too late for that.}
18.Kd1 $1 {Now the menaced Rook must scurry back, for capture
on a2 would be much too dangerous.} 18...Rc6 $1 {At last,
Black gets the right idea: overprotecting his Pawn at e6. But
it is already too late.} 19.Re2 Ke7 {Introduced into
tournament play by myself. See note to White's 14th move. The
King overprotects e6.} 20.Rhe1 Re8 $1 21.Nf3 $1 {Completing
the overprotection of e5 and thus deciding the fate of the
game. Black has no defence. Note the aesthetic effect created
by White's position.} 21...Bf8 {Now Black threatens to
complete the overprotection of e6 by playing Ng7. But White
has prepared a brilliant combination.} 22.g4 $1 {Much stronger
than the obvious Bg5+ etc.} 22...hxg4 23.Qh7 $1 {Now one
clearly realizes the masterly understanding of position which
went into White's eighth move (Qh2!).} 23...gxf3 {Had Black
continued overprotecting by 23...Ng7 there would have followed
24.Bg5+ f6 25.Bxf6+ Kf7 26.Ng5 mate. Black's basic error was
that he started overprotecting much too late.} 24.Bg5# {One of
my best games! I am proud of it if only because Herr
Systemsson is one of the strongest Scandinavian players. The
game made an overwhelming impression on the players and
spectators as well as on my opponent. The game has become
famous in Denmark as "the immortal overprotection game."} 1-0

1. e4 { Notes by Raymond Keene. } e6 {Before concluding this
discussion of Nimzowitsch's handling of the French Defence
from the Black side we must mention his original treatment of
the Orthodox variation -- which has points in common with his
own defence and his interpretation of the Winawer.} 2. d4 d5
3. Nc3 Nf6 4. Bg5 Be7 5. e5 Ng8 {!? This unusual move, or
rather the strategic conception underlying Nimzowitsch's
interpretation of this move, contains in itself the
quintessential Nimzowitschian paradox: provocation and
prevention, under one roof, as it were. White will naturally
wish to administer sharp punishment for the 'insult' involved
in returning the knight to its initial square,
e.g. Levy-Heidenfeld, Dublin 1968: 5...Ng8 6 Be3 b6 7
g4?!. But such violence may later react to White's
disadvantage, especially if he continues in like vein. As to
prophylaxis: with White's pawn chain established on dark
squares and with White in possession of a 'territorial plus'
on the kingside Black must over-protect the kingside light
squares (f5/g4/g6) to forestall a kingside pawn avalanche by
White along the lines of (eventually) f2-f4/g2-g4 and
f4-f5. Bizarre though it may appear 5...Ng8 achieves far more
in the direction of the said over-protection (since the knight
can redeploy via e7 or h6 to f5) than does 5...Nfd7. The
disadvantage, of course, is the 'anti-development' of a piece,
but so long as Black avoids a premature ...c7-c5 the position
will remain closed and virtually impervious to breakthrough;
and, after all, is d7 such a marvellous square for the Black
king's knight? } 6. Be3 b6 7. Qg4 {?! In a detailed discussion
of the whole 5...Ng8 variation (Chessman Quarterly, 1970) the
Irish International John Moles recommended 7 h4! giving as a
reasonable continuation: 7...h5 8 Be2 g6 9 Nf3 Ba6 10 Qd2 Bxe2
11 Nxe2 Nc6 followed by ...Qd7 and ...O-O-O. Perhaps White is
slightly better, although Black's set-up is extremely tough. }

21. dxc5 bxc5 22. Kg2 Qb6 {Black's plan is to attack White's
e-pawn until f2-f4 becomes necessary and then to eliminate
White's advanced knight (...Bxg5) at a moment when White
cannot recapture with his bishop. (Nimzowitsch) } 23. f4 {?!
Playing it at once saves Black a lot of trouble. } 23...Bxg5

beautiful combination, one of the most impressive I have ever

overpowering. 32 Rdxd2 is also unplayable since the knight
hangs. } 32...Rxd2 33. Bxd2 Rd8 {Threatening ...Rd3xg3. }
34. Qe2 {On 34 Bc1 Nimzowitsch planned 34...Rxd1 35 Qxd1 Qf2
36 Ne2 Kc8! 37 Qa4 Qf3-+. If 37 a4 Nce7 followed by ...Nd5 and
...Ne3 and White is paralysed. A wonderful variation. }
34...Rd3 35. Nf3 Qd8 36. Rf1 Qd5 37. Rf2 h4 {! The climax of
the combination. White loses his queen. Observe the remarkable
paralysis that has seized White's pieces after the inspired
pawn sacrifice on move 32. } 38. gxh4 Ncd4 39. cxd4 Nxd4
40. Qxd3 cxd3 41. Nxd4 Qxd4 42. Kg3 Qe4 {?? With 42...Qa1!
Nimzowitsch could have crowned his outstanding
combination. White cannot prevent the loss of the a-pawn and a
black victory is assured. After the text Saemisch succeeds in
protecting his a-pawn and, unbelievably, Black's advantage is
insufficient to win. After further serious errors by White
Nimzowitsch did eventually win from this drawn position on

1. c4 {Notes by Nimzowitsch} c5 2. f4 {This move may give a
bad impression, but as we will see soon the wrong thing isn't
the move but the impression!} Nf6 3. d3 d5 { Otherwise 4.e4
would have followed, giving Hansen a solid position} 4. cxd5
Nxd5 5. e4 {You may compare this position to my Dresden
variation: 1.c4 c5 2. Nc3 Nf6 3.Nf3 d5 4.cxd5 Nxd5 5.e4 The
two positions have in common the d3 pawn and the opened d
column, but in the game the Black's best resource ...Nxc3
followed by ...g6 isn't playable. Consequently, Mr. Hansen
opening is ingenious and praiseworthy.} Nf6 6. Be3 {!} e6

follwed by Be2 was much more solid. For instance: 9. ... Nh5?
10.Kf2 and then 11.g4. With this move, White demonstrates not
to have a good intuition for solid positions (a player like
F. Saemisch wouldn't even think about a move like d4!)} cxd4
10. Nxd4 Bb4 { White's position is already trembling} 11. Nxc6
Bxc6 12. Qxd8+ Rxd8 13. e5 { White has lost most of his
powerful center and has to face his weakness on white squares}

final with opposite colours Bishops} Bxc3+ 15. bxc3 Nxc3
16. Bc4 {Now 16.Bxa7 is impossible due to 16. ... Nd5 and f4
is undefendable. (Obviously not 17.g3? Nxf4 18.gxf4 Bxh1)} Rc8
{The most suitable strategy against a an expanded formation!
Leaving everything "hanging" and increase the pressure}
17. Rc1 Bxg2 18. Rg1 Rxc4 19. Rxg2 b5 20. Rgc2 { Or 20.Rg7 Ke7

Knight!} 21. Rxc4 bxc4 22. Rxc4 Kd7 23. Bxa7 Rc8 {The triumph
of the solid position! The smart White player has earned back
all he could (his opponent's material advantage), but now he
has got a "fluttering butterfly" in f4, an "unleashed dog" in
a7, and two "lost sheep" in a3 an h2, while the King is
sitting at proper distance on his throne... The end is
terryfing!} 24. Re4 { After 24.Rxc8 Kxc8 the "butterfly'"
would have stopped fluttering} Rc1+ 25. Kf2 {If 25.Kd2 then
