9. Ngf3 Be7 10. Kf1 $2 $146 {Really? Well, if I were following the game
transmitted live on playchess.com server, I would have thought that White in
fact played 10.0-0, while 10.Kf1 is just a mouse slip by someone relaying the
game. However, before continuing to be harsh and putting a glaring question
mark to the move in the text, let's think what could be White's ideas behind
10.Kf1? White assumes that the king is safe enough on f1, while the rook on h1
will support the advance of White's h- and maybe also g-pawn. This is how he
is going to attack Black's king's residence. Sounds too good to be true? Yes,
it is, and the continuation of the game proved it. A standard play would
include, obviously, castling followed by Nf3-e5 at some point. Here is one
recent example:} (10. Ne5 Bh5 11. Qc2 Nd7 12. O-O Ndxe5 13. Bxe5 Nxe5 14. dxe5

Grandmaster Harikrishna with a score of 2-0 and 1.5-0.5, I had to face the
experienced local superstar Shakriyar in the third round. I had a rest day

tiebreaks. So I was making a note of all the options my opponent would play

dominating position and a clean initiative even after 16...Rc6 and Black lacks
development and co-ordination. So still it remains a mystery why and on what
basis I entered into this variation which is hard for myself to explain.} 17.

d5 3. exd5 {Together with the following move, the most common attack against
the Caro-Kann Defence. (Tarrasch) Two or three years ago the Caro-Kann was
reckoned to be the safest defence with which to obtain a draw. White normally
continued 3.Nc3 dxe4 4.Nxe4, dissolving the tension in the centre and setting
the game on peaceful paths. The Caro-Kann owes its reputation to Capablanca,
who perfected his drawing technique with Black in the aforementioned variation.
As far as the variation 3. cxd5 exd5 4.Bd3 Nf6 5.Bf4 Nc6 6.c3 Bg4 is concerned,
he even evaluated it as favourable to Black, who can achieve a pawn advance on
the queenside in the middlegame. It is interesting to point out that Flohr has
frequently carried out successfully this attack, and also along similar lines
in the Queen's Gambit. However the situation has changed since last year. The
Moscow player Panov introduced a new attack, which has even been named after
him. The Panov Variation has become in the hands of the present World Champion
Alekhine an extremely dangerous weapon and not till a few months before the
start of this match were effective antidotes found for Black. In the present
game White tries to strengthen the Panov System once more. (Botvinnik) In
Verbindung mit dem folgenden Zuge der jetzt gebrдuchlichste Angriff gegen die
Caro-Kann-Verteidigung. (Tarrasch) Vor zwei bis drei Jahren galt die
Caro-Kann-Verteidigung als die am sichersten zum Ausgleich fьhrende
Verteidigung. WeiЯ setzte gewцhnlich mit 3.Nc3 dxe4 4.Nxe4 fort, womit die
Bauernspannung im Zentrum aufgelцst und die Partie in friedliche Bahnen
gelenkt wurde. Die Caro-Kann-Verteidigung verdankt ihre Reputation namentlich
Capablanca, der seine Remistaktik mit den schwarzen Steinen in der erwдhnten
Variante zur Vollkommenheit fьhrte. Was die Variante 3. cxd5 exd5 4.Bd3 Nf6 5.
Bf4 Nc6 6.c3 Bg4 angeht, so schдtzte er sie sogar zu Gunsten des Schwarzen ab,
der im Mittelspiel einen Bauernmarsch am Damenflьgel durchfьhren kann. Man
sollte interessehalber erwдhnen, daЯ Flohr diesen Angriff, auch analog im
Damengambit, mit oftmaligem Erfolg durchfьhrte. Allerdings hat sich die
Situation seit dem vergangenen Jahr geдndert. Der Moskauer Schachspieler Panov
fьhrte ein neues Angriffssystem ein, das auch seinen Namen erhielt. Die
Panov-Variante wurde in den Hдnden des jetzigen Weltmeisters Aljechin zu einer
дuЯerst gefдhrlichen Waffe und erst einige Monate vor Beginn dieses
Wettkampfes fand man fьr Schwarz wirksame Gegengifte. In der vorliegenden
Partie versucht WeiЯ erneut das Panov-System zu verstдrken. (Botvinnik)} cxd5

"?" This is bad, because it helps my opponent develop and gives him the bishop
pair which goes on to wage a victorious campaign agians the knights. However
White gets a passed pawn and, above all: for the endgame Black's four kingside
pawns are not much better than White's three, so that White is in reality a
pawn ahead. It has to be said that all these relationships were hard to see
through and it was hard to weih up the advantages and disdvantages of the
exchange. So White had to quickly decide on the simple continuation Qd3: which
always meant a good game for him. (Tarrasch) The opinion has frequently been
expressed that players are often stuck at the board with the blunders that
were made in home analysis. It is bad for a player to lay too much trust at
the board on the lines he has worked out previously. This is what happened in
the present game.  Of course it would never occur to me in a normal tournament
game to make this exchange without a specific reason. White's 10th move is the
fruit of insufficiently deep home analysis. Because in the second line I had
worked out (10.Nf3 e6 11.0-0-0? Be7 12.Rxd3 exd5!), Back was more or less
comfortable, I chose 10.Bxf6. In the absence of calculated concrete variations,
I decided that Black would not be able to prevent the exchange of one of his
bishops, which would bring into relief the strength of the passed d-pawn. But,
as becomes clear in the future course of the game, Black will manage to retain
his bishop pair and to blockade the d5-pawn reliably. (Botvinnik) "?" Das ist
schlecht, denn es entwickelt den Gegner und gibt ihm das Lдuferpaar, das in
der Folge gegen die Springer einen siegreichen Kampf fьhrt. Allerdings bekommt
WeiЯ einen Freibauern und vor allem: fьr das Endspiel werden die vier Bauern
des schwarzen Kцnigsflьgels nicht viel mehr wert sein als die drei weiЯen,
sodaЯ WeiЯ eigentlich einen Bauern mehr haben wird. Zuzugeben ist, daЯ alle
diese Verhдltnisse undurchsichtig und die Vorteile und Nachteile des
Abtausches schwer gegen einander abzuwдgen waren. Um so eher aber muЯte sich
WeiЯ dann fьr die einfache Fortsetzung Qd3: entschlieЯen, die ihm immer ein
gutes Spiel sicherte. (Tarrasch) Wiederholt ist die Meinung geдuЯert worden,
der Spieler sei am Brett oft vor den Schnitzern gefeit, die in der Hausanalyse
gemacht werden. Und schlecht ist es, wenn der Spieler am Brett zu sehr seinen
vorher ausgearbeiteten Varianten vertraut. So geschah es auch in vorliegender
Partie.  Selbstverstдndlich kдme mir nicht in einer gewцhnlichen Turnierpartie
in den Sinn, ohne einen besonderen Grund auf diesen Tausch einzugehen. Der
zehnte Zug des WeiЯen ist die Frucht einer ungenьgend tiefen Hausanalyse. Weil
in der zweiten von mir ausgearbeiteten Variante, 10.Nf3 e6 11.0-0-0? Be7 12.
Rxd3 exd5!, eher Schwarz bequem steht, wдhlte ich 10.Bxf6. In Ermangelung
ausgearbeiteter konkreter Varianten entschied ich, daЯ Schwarz den Abtausch
eines seiner Lдufer nicht verhindern werden kann, wonach sich die Stдrke des
freien d-Bauern zeigen sollte. Wie aus dem weiteren Gang der Partie
ersichtlich, wird es Schwarz aber gelingen, sein Lдuferpaar zu erhalten und
den Bauern d5 zuverlдЯig zu blockieren. (Botvinnik)} ({If White now simply

carefully stops, and is correct in his judgement. (Tarrasch) "!" Completely
correct. First, Black puts his bishops on the d-file, after which the d5-pawn
loses all of its power, and then he manages to guard his bishops against
sorties by the opposing knights. (Botvinnik) "!" Schwarz fьrchtet sich nicht
vor dem Freibauern, den er sofort sorgfдltigst stoppt, und behдlt mit seinem
Urteil recht. (Tarrasch) "!" Vollkommen richtig. Als erstes stellt Schwarz
seine Lдufer auf der d-Linie auf, wonach der Bauer d5 seine gesamte Kraft
verliert, danach gelingt es ihm, seine Lдufer vor den Ausfдllen der
gegnerischen Springer zu bewahren. (Botvinnik)} ({Entschieden schwдcher wдre}

rook then have to move again to break the pin? What sort of principles are
that for planning! (Tarrasch) Ein doppelter Fehler: der Turm gehцrt
selbstverstдndlich auf eine offene Linie und nicht auf eine geschlossene; und
dann: was soll geschehen, wenn der Gegner durch den sehr naheliegenden Zug Bg4

nochmals ziehen? Was sind das fьr Prinzipien in der Spielfьhrung! (Tarrasch)} (

correct plan was to regroup by Ne2-d4-f3 and then exchange rooks on the e-file.

the opposing bishops and thus does not hit on this plan at once. After the
text move, Black's position is obviously preferable. (Botvinnik) und

fьr WeiЯ bestand in der Umgruppierung Se2-d4-f3 und anschlieЯendem Abtausch
der Tьrme auf der e-Linie. Leider ist WeiЯ aber noch voller Hoffnung, einen
der beiden gegnerischen Lдufer abtauschen zu kцnnen und verfдllt deshalb nicht
sofort auf diesen Plan. Nach dem Textzug verdient die schwarze Stellung
offensichtlich den Vorzug. (Botvinnik)}) 14... Bg4 {This looks dangerous but
does not really pressurise White. Of course Black does not worsen his position.
In the course of the next moves, Black systematically limits the freedom of
action of the knights. (Botvinnik)   Das sieht gefдhrlich aus, bedrдngt aber
den WeiЯen in Wirklichkeit nicht. Freilich verschlechtert Schwarz seine
Stellung nicht. Im Verlauf der weiteren Zьge begrenzt Schwarz planmдЯig das
Tдtigkeitsgebiet der Springer. (Botvinnik)} 15. Rd2 {This move lacks any
positional sense! How can the rook leave the first rank when the opposing rook
dominates the open file! White should without any embarrassment move his rook
to e1. But perhaps Botvinnik was embarrassed about showing his countrymen such
a spectacle in the first game of the match. (Weaker players will ask: "Why not
simply f2-f3?" that lossens up the position and exposes the king to a check
from the b6-g1 diagonal. Experienced players avoid such moves.) (Tarrasch) Das
ist ein Zug ohne jedes Positionsgefьhl! Wie durfte der Turm die erste Reihe
verlassen, wo der feindliche Turm die offene Linie beherrscht! WeiЯ sollte den
Turm, ohne zu errцten, nach e1 ziehen. Aber wahrscheinlich genierte sich
Botwinnik, seinen Landsleuten in der ersten Partie des Wettkampfs ein solches
Schauspiel zu bieten. (Der schwдchere Spieler wird fragen: "Warum nicht
einfach f2-f3?" das lockert die Stellung und setzt den Kцnig einem Schach der
Diagonale b6-g1 aus. Der Geьbte vermeidet solche Zьge.) (Tarrasch)} a6 {

weak move, because only a few moves later the knight beats a rueful retreat to
its departure point! Knights belong in the centre, where they are even
superior to bishops. (Tarrasch) Auch wieder schwach gespielt, denn wenige Zьge

his major pieces on a closed file! He protects the isolated queen pawn, which
is not even being attacked, for the fourth time! Botvinnik is probably a
victim of Nimzowitsch's erroneous teachings about overprotection. Or perhaps
he wanted to follow my rule: "Rooks belong behind passed pawns."? That however
would be a grotesque misunderstanding, because of course my rule is true for
the endgame and not for the opening. (Tarrasch) White is still marking time.
The immediate 18.Re2 was better, offering an exchange of rooks. (Botvinnik)
Wieder ein eines Meisters unwьrdiger Zug! Auf der geschlossenen Linie massiert

meinen Satz: "Die Tьrme gehцren hinter Freibauern." haben befolgen wollen? Das
wдre allerdings ein groteskes MiЯverstдndnis, denn dieser Satz gilt natьrlich
fьr das Endspiel und nicht fьr die Erцffnung. (Tarrasch) WeiЯ tritt noch immer

will lose the d5-pawn . When the game was resumed on the 30th November, White
prolonged his pointless resistance by another three moves. (Botvinnik)  Damit
ist das Endspiel entschieden, obwohl die Krдfte vorlдufig noch gleich sind.

dieser Stellung wurde die Partie abgebrochen. Falls WeiЯ versucht, die
Kцnigsflьgelbauern zu retten, so ist leicht zu erkennen, daЯ er den d5-Bauern

nutzlosen Widerstand noch um drei Zьge. (Botvinnik)} 38. Kd4 Bf1 39. h4 Bxg2

passed pawn. After Kc6 or Kd6 it cannot advance and after d5-d6 it is stopped
by K-e6-d7. But Black can easily create an unstoppable passed pawn, best of
all by h5 and g5.  In game 11 (Vol. 5 [Rauzer-Botvinnik, Leningrad 1933])
Botvinnik charmed us all with his brilliant moves; but the present game also
shows that he is capable of making really bad ones, and even a lot of them in
a single game. Flohr has demonstrated considerable superiority. After this
single game, my prognosis for Botvinnik in in the match is very unfavourable.
Readers will perhaps find my criticism of this game very strong and perhaps
regret my use of the term "really bad moves". But a master can have a bad game,
and on occasion that happens to all of us; it can also happen that his
attention slips and that he gives away a piece; that is human and a human
being is not a machine. But there are certain moves which a master should
absolutely never make and these are the domain of the woodpusher. Botvinnik's
genius is capable of bearing him to the heights of chess Olympus, but also to
the depths of the chess underworld. (Tarrasch) White resigned because Black
even wins by simply sacrificing his bishop for the pawn and then pshing
through one of his kingside pawns to the queening square. (Botvinnik)  Und
WeiЯ gab auf, denn er kann seinen Freibauern nicht zur Geltung bringen. bei
Kc6 oder Kd6 kann er nicht vor und bei d5-d6 wird er durch K-e6-d7 gestoppt.
Schwarz aber kann sich leicht einen unaufhaltsamen Freibauern verschaffen, am
besten durch h5 und g5. - In Partie 11 (Heft 5 [Rauzer-Botvinnik, Leningrad
1933]) hat Botwinnik durch seine genialen Zьge entzьckt; die vorliegende
Partie zeigt, daЯ er auch fдhig ist, Stьmperzьge zu machen und zwar in einer
Partie eine ganze Anzahl. Flohr hat eine bedeutende Ьberlegenheit bewiesen.
Nach dieser einen Partie stelle ich fьr Botwinnik in dem Wettkampf eine sehr
ungьnstige Prognose. Die Leser werden meine Kritik dieser Partie sehr scharf
finden und vielleicht den Ausdruck "stьmperhaft" bemдngeln. Aber ein Meister
kann Partien schlecht spielen und das passiert gelegentlich jedem; es kann
auch vorkommen, daЯ seine Aufmerksamkeit erlahmt und er eine Figur einstellt,
das alles ist menschlich und der Mensch ist keine Maschine. Aber es gibt
gewisse Zьge, auf die der Meister nicht verfallen d a r f; diese bilden das
Reservatrecht des Stьmpers. Botwinniks Genius hat eben die Fдhigkeit, sich zu
den Hцhen des Schach-Olymps aufzuschwingen, aber auch, zu den Tiefen der
Schachunterwelt hinabzusteigen. (Tarrasch) WeiЯ gab auf, weil Schwarz selbst
dann gewinnt, wenn er einfach seinen Lдufer gegen den d-Bauern opfert und
anschlieЯend mit seinen Kцnigsflьgelbauern zur Dame lдuft. (Botvinnik)} 0-1
