Annotated game.
White: M. Taimanov, 2600.
Black: B. Larsen, 2650.
Event: Vinkovci 1970.
Result: 0-1 in 34 moves.
Opening: Nimzo-Indian Defence, Classical Variation, Berlin Variation, E39.
1. d4 Nf6
2. c4 e6
3. Nc3 Bb4
| This move introduces the Nimzo-Indian Defence. There are many systems
available to both white and black according to how each replies to the choices
of the opponent. While some lines have much better reputations than others,
there are no pronounced, "Best", variations. Instead one must choose a system
which suits your style of play. If sifting a variation from an opening book or
database is not easy for you, then instead search for those variations played
by a top player you admire and follow their example. This,
"Repertoire-acquisition", is a clever means of having someone else do all the
hard work on developing an opening repertoire. Ah, and while you might admire
the pioneers of Steinits, Lasker, Capablanca, please remember they have not
been updating their repertoire for a while, and are unlikely to do so in the
near future. Select someone of Elo 2500+ who has been competing regularly over
the last 5 years or so to become your, "Unofficial Coach For Opening Systems".
They will be searching for opening innovations, borrowing improvements from
others, and then incorporating both into their play. Much easier than having to
do it all for yourself, right? This is not a perfect solution but should be a
good start for anyone feeling their approach to building a repertoire could be
in need of an overhaul. ||
4. Qc2
| This is the Capablanca Variation, popular when the Nimzo-Indian Defence was
in the early days of exploration. The idea is to avoid doubled c-pawns should
black play, Bxc3+. The downside is that white might be investing a couple of
queen moves in the opening, and can quickly fall behind in development,
especially over on the kingside. It became unpopular at the top level as
players with the black pieces began to find means of achieving equality with
chances of taking an advantage if white does not accept black has equalised.
However, in the 1990s Kasparov revived it with new ideas and nowadays this
variation is played at the top level again.
The other main choice here is, 4. e3, the Rubinstein Variation. Lastly, for
players with a dynamic sense of play, there is, 4. f3, to be explored, but take
care, there are some very sharp lines demanding tactical awareness lurking
therein. ||
4. ... c5
| The Pirc Variation, trying to exploit the undefended white d4 pawn due to the
white queen having drifted onto the c-file. Instead, 4. ... O-O, or, 4. ... d5,
or, 4. ... Nc6, are the other main choices here. ||
5. dxc5
| Experience reports this capture is the correct way to meet this black central
challenge. Those who enjoy spotting transpositions within openings might feel
their antennae twitching to the scent of a possible change of direction toward
the Queen's Gambit Declined. ||
5. ... O-O
| Black is in no hurry to regain the pawn, it cannot be sensibly defended by
white. ||
6. Bf4
| Instead, 6. Nf3, or, 6. a3, or, 6. Bg5, are the other main choices here. ||
6. ... Bxc5
| Black regains the pawn before white makes mischief with a possible, Bd6. The
white c5 pawn would not be secure, black has, Na6, ganging up on the pawn to
capture it, but why let white push you into such manoeuvring when the simple,
Bxc5, is available? ||
7. Nf3 Nc6
| Or, 7. ... d5, transposing into the QGD territory as anticipated. ||
8. e3
| Or, 8. a3, preparing a possible queenside pawn expansion if black is willing
to allow such a luxury. ||
8. ... d5
9. a3
| Or, 9. Rd1, placing pressure on the centre is the other main choice here. ||
9. ... Qa5
| Re-creating the pin on the white c3 knight and also placing an x-ray attack
on the white a1 rook. A feature of this system is that white falls behind in
development of the kingside, which means black can make plans against the white
c3 knight. Also known here are, 9. ... Qe7, 9. ... Re8, 9. ... Be7, but need a
little more testing at the top levels before they can satisfactorily replace
the game choice. ||
10. Rc1
| A parting of the ways has occurred. Instead, 10. Rd1, or, 10. O-O-O, or, 10.
Nd2, are the other main choices and lead to significantly different middlegame
plans for both players. ||
10. ... Be7
| Blac needs to retreat this bishop to avoid the threatened white, 11. b4,
which would cost black a piece for two pawns. ||
11. Be2
| Instead, 11. Qa4, challenging the somewhat annoying black queen was also to
be considered. ||
11. ... dxc4
| Black has deliberately delayed this capture until white has spent a tempo
developing the f1 bishop. Such is life in QGD-style systems. Instead, 11. ...
Ne4, or, 11. ... Bd7, could be considered if black wishes to keep the central
tension. ||
12. Bxc4 Nd5
| When employing the Nimzo-Indian Defence, 3. ... Bb4, black was planning
pressure in a variety of ways on the white c3 knight. As the opening morphed
into the middlegame this plan has not been abandoned. In fact, if black is
allowed so to do, the pressure will increase with, 13. ... Bf6, threatening,
Nxc3, forcing white to reply with a pawn capture, resulting in the loss of the
a3 pawn. White is not letting this happen, and since the black knight is going
to be the aggressor in this black plan, then the white defensive response seems
easy to find. ||
13. Bxd5 exd5
| White has given up the bishop pair to relieve the pressure but in doing so
has released the skulking black c8 bishop for action. There is of course in
return now an isolated black d5 pawn which can be targetted once white
completes development. These are the sort of imbalances which club players
should be seeking if they wish to set tests for the opponent. ||
14. Qb3
| Grand Rabbit wishes to humbly suggest that the black d5 pawn is always going
to be a target and that Grand Master should have postponed this queen move in
favour of, 14. O-O. Once the king is safe then slow building of pressure in the
centre seemed a simpler path to tread. Though in fairness to the Grand Master,
Grand Rabbit could only discover this with the use of a 20 - 20 hindsight
microscope.
Now black spots a lovely trick which totally disrupts the white coordination.
||
14. ... g5
| The dividing line between Grand Mastery and Grand Rabbitry is far wider than
one thinks.
New concept for middlegame strategy books - "An attack against an unsecured
centre should be countered with a loosening wing assault", right? This is
actually a well-judged tactical thrust, but would leave many positional players
shaking their heads in disbelief. It is possible to make such apparently
weakening moves and survive, but to do so one must have faith in your ability
to cope with sharp tactics around your own king. There is of course nothing
wrong with, 14. ... Be6, apart from the fact that it is a defensive response,
and Larsen is renowned for playing dynamic chess. ||
15. Bg3
| White calculates the pawn is toxic. If, either, 15. Bxg5, or, 15, Nxg5, black
will reply with, 15. ... Bxg5, leaving white to recapture with the remaining
minor piece. Black then reveals the latent power of x-ray attacks with, 16. ...
d4, the white c3 knight is attacked as is the unprotected white minor piece on
the g5 square from the a5 queen. The surprising, 14. ... g5, would not have
worked had white castled kingside on the previous move because the white queen
would still be on the c2 square. The line would have run, 14. O-O g5 15. Bxg5
Bxg5 16. Nxg5, and while the sneaky, 16. ... d4, does indeed attack the two
white knights, unfortunately, 17. Qxh7+ mate, rather spoils the party.
After the coaching study was over, a suggestion of, 15. Be5 was offered when it
gets rather tricky. The idea is, 15. Be5 g4 16. Qxd5 Qxd5 17. Nxd5 gxf3, and it
appears that black has snatched a piece. Not so, white undermines the black e7
bishop with, 18. Rxc6, when, 18. bxc6 19. Nxe7+, is a pleasing knight mate.
Black can improve on the line just offered, when white hits with, 18. Rxc6,
black retreats with, 18. ... Bd8, but then 19. Nf6+ Bxf6 20. Rxf6 Re8 21. Bc3
fxg2 22. Rg1 Re6 23. Rxg2+ Kf8, and black is a pawn down though opposite
bishops might assist in the fight for a draw.
Black can improve significantly over all this with, 15. Be5 g4 16. Qxd5 Bd8,
when white has problems with the attack on the f3 knight. If then, 17. Qxa5
Bxa5, and if the f3 knight moves the white e5 bishops falls to, Nxe5.
If instead, 15. Be5 g4 16. Qxd5 Bd8 17. Nd4 Nxe5, white loses a piece. ||
15. ... g4
16. Nd4
| Perhaps, 16. Ne5, would prevent the forthcoming material imbalance from
arising? ||
16. ... Nxd4
17. exd4 Bg5
| Ouch! The black bishop gains an attack tempo on the white c1 rook while
threatening an annoying, Re8+, disrupting any white thoughts of castling into
safety. It seems white must accept either a material loss or suffer problems of
getting the h1 rook into the fight. ||
18. O-O
| If one plays moves like this with sufficient confidence there is a remote
possibility the opponent might think this is a planned positional sacrifice of
the exchange. All the World's a stage... ||
18. ... Bxc1
| Only time will tell if this is a win of an exchange or an ill-considered
bishop sacrifice. ||
19. Rxc1 Be6
| White to play has some hard thinking on how to proceed. Trying to tough it
out with this material imbalance should ultimately fail. There are no
weaknesses in the black position, simple consolidation followed by challenges
will lead to an endgame where the black rook will simply outplay the remaining
white minor piece. This means white must find something in the middlegame, but
what?
Grand Rabbit shall try to unravel the thinking necessary to create something
from this apparent nothingness.
Well, the presence of opposite colour bishops might assist, by definition
neither can challenge or block out the activity of the other.
In fact, if the white dark square bishop becomes powerful the only means to
eliminate it is with a countering return of the exchange.
Combine this with black choosing to advance, pawn g5, and, pawn g4, and the
thought of a mating pattern with the focus on the g7 square should come to
mind.
Yes, the white pieces are far from setting this up, but since slow play is a
defeat waiting to happen, then simply release those creative juices, pay little
heed to material costs, and last but not least, cross your fingers for good
luck.
And if you don't believe there is luck in chess, then how about a quick prayer
to Kaissa, she might just decide to smile your way.
The first requirement will be a bishop either on, e5, f6, or, h6.
Next the white queen must have a very quick entry route over to the kingside,
and when we say quick, that does mean as quick as possible.
The obvious entry square for the white queen is g3, and since the g3 bishop is
thinking of landing on e5, then the vacation of the g3 square is already part
of the plan.
At some point the white c3 knight will need to jump off the 3rd rank to allow,
Qg3.
Lastly, wouldn't it be even better if the white queen could be transported to
g3 and land giving check to the black king?
But how can this happen if there is a black pawn on the g4 square?
Simple, one just invites the black g4 pawn to reside elsewhere.
So a vague plan is emerging.
Firstly, lure the black g4 pawn off the g-file.
Secondly, advance with, Be5, controlling all those lovely weakened dark squares
around the black king.
Thirdly, the c3 knight needs to jump aside,backward, or forward, according to
taste, just get it out of the way.
Fourthly, the queen swings across to g3 with checkmate, if the black kingside
has not made any alterations to disrupt the mating pattern.
Nothing wrong with having a dream, is there?
Fifthly, since white is already an exchange down, losing / offering further
material along the way should not inhibit the creative process.
Sixthly, no consideration of how black could play has been considered while
devising the above Inspirio-desperation.
If there is a refutation to our master-plan then so be it.
All one can do is ask questions of your opponent and be prepared to play boldly
if they seem to be drifting off course. ||
20. h3
| Phase One, invite the black g-pawn to move off the g-file. During the
coaching session a slower plan of, 20. Rf1, to be followed by, pawn f3, open up
the f-file for the rook, and then swing the knight and queen over to the
kingside was suggested. It is a less tactical means of handling the position.
One fact which is difficult to disagree with is that the dark squares must be
exploited, and this slower treatment still plans such activity. Another
suggestion during the session was, 20. Qxb7, intending, Qe7, entering the black
kingside dark squares with a useful snatch of a pawn along the way. Fine, but
perhaps after, 20. Qxb7 Qb6, white has to choose between trading queens and
fight like mad for a draw, or go for the kingside with, 21. Qe7, but then
comes, 21. ... Qxd4, and the black queen is swinging over to the kingside to
defend. Perhaps white could continue with 22. Bh4, thinking of invading with,
Bf6, but, 22. ... Rfe8 23. Qg5+ Qg7, seems to stop all thoughts of a mating net
and black has managed to create a passed d-pawn into the bargain. ||
20. ... gxh3
| Very obliging. Is black impervious to the white machinations? ||
21. Be5 f6
| White achieves Phase Two, a bishop poking itself at the g7 square, only for
black to squish it out, wouldn't one say? What price our master-plan now? Once
you enter the Chess-Casino but start losing the only answer is to increase the
stakes if you wish to emerge with a profit. Again fine strategy, but surely if
white now loses a piece then the debit will be a whole rook, won't it? The
dividing line between, "In for a penny, in for a pound", and, "In for a penny,
in for a pounding", is sometimes very narrow.
It is now a case of finding inspiration or it will be resignation to
resignation soon. ||
22. Ne4
| Phase Three achieved, the 3rd rank has been cleared, but there are now two
white minor pieces up for capture, aren't there? Another gain of Phase Three,
vacation of the c3 square by the white knight, also opened the c-file for some
very useful rook activity, assuming there are actually any white pieces
remaining on the board with which it could coordinate. ||
22. ... fxe5
| The alternate capture is an immediate disaster as the following sample lines
might demonstrate:
(A). If, 22. ... dxe4 23. Qxe6+ Kh8 24. Bxf6+ Rxf6 25. Qxf6+ Kg8, 26. Rc3,
forces black to give up the queen with, 26. ... Qxc3, to avoid, Rg3+ mating.
(B). Or if, 22. ... dxe4 23. Qxe6+ Kg7 24. Rc7+ Kg6 25. Qg4+ Kh6 26. Qg7+ Kh5
27. g4+ Kh4 28. Bg3+ mate, is a dark square joy to behold.
(C). Or if, 22. ... dxe4 23. Qxe6+ Kg7 24. Rc7+ Qxc7 25. Bxc7, is a decisive
material advantage for white.
(D). Or if, 22. ... dxe4 23. Qxe6+ Rf7 24. Rc7 Rac8 25. Qg4+ Kh8 26. Bxf6+ Rxf6
27. Qg7+ mate, more dark square neatness.
(E). Or if, 22. ... dxe4 23. Qxe6+ Rf7 24. Rc7 Qxc7 25. Bxc7, is a decisive
material advantage for white.
The theme of black giving up the queen to eliminate an invading white rook will
occur again as the potential complications, confined to the notes because black
won't comply, are unravelled. ||
23. Qg3+
| Phase Four complete, albeit at the extra cost of the white bishop. In return
white now has a queen and knight floating around in the kingside, with possible
rook lifts to c3 and maybe c7, depending how play goes. Black to play must now
be precise or suffer the consequences.
Clue: Black is a rook up, surely more than is necessary for victory? ||
23. ... Bg4
| Brilliant!
Having just witnessed the disasters awaiting black had, 22. ... dxe4 23. Qxe6+,
been played, it might not be a surprise to find the following few sample lines
demonstrate the white master-plan was equally dangerous had black miscalculated
here:
(A). If, 23. ... Kh8 24. Qxe5+ Kg8 25. Qxe6+ Kh8 26. Qe5+ Kg8 27. Rc3,
threatening a ruinous check on g3, so black could reply, 27. Qxc3, but now, 28.
Qxd5+ Kh8 29. bxc3, gives white a decisive material advantage.
(B). Or if, 23. ... Kh8 24. Qxe5+ Kg8 25. Qxe6+ Kh8 26. Qe5+ Kg8 27. Rc3 Rf7
28. Rg3+ Kf8 29. Nd6, attacks the black f7 rook while keeping the option of,
Qh8+, winning the black a8 rook. If now, 29. ... Rd7, then 30. Qf6+, mates next
move.
(C). Or if, 23. ... Kf7 24. Ng5+ Ke7 25. Qxe5 Rf6 26. Rc7+, might be inviting,
26. ... Qxc7, but, 27. Qxc7+ Ke8 28. Nxe6 Rxe6 29. Qxh7, threatening that
ruinous h8 check, so, 29. ... Rd8 30. Qxh3, and the white kingside connected
passed pawns will be difficult to stop, white must be winning this.
(D). Or if, 23. ... Kf7 24. Ng5+ Ke7 25. Qxe5 Rf6 26. Rc7+ Qxc7 27. Qxc7 Bd7
28. Qe5+ Be6 29. Nxe6 Rxe6 30. Qc7+ Kf6 31. Qxb7 Rg8 32. g3, and black cannot
keep the many loose pawns, a7, d5, h7, and h3, white should win this one with
careful technique.
(E). Or if, 23. ... Kf7 24. Ng5+ Ke7 25. Qxe5 Qb6 26. Rc7+ Kd8 27. Nxe6+ Qxe6
28. Qxe6 Kxc7 29. Qe7+, and black must be careful here. Clearly, 29. ... Kc8,
losing both the f8 and a8 rooks will not happen. Instead after, 29. Qe7+ Kc6,
there would follow, 30. Qc5+ Kd7 31. Qxd5+ Kc7 32, g3, and white should win
with good technique, but much time will be involved to take the point. Lastly,
after 29. Qe7+ Kb6, there is, 30. Qc5+ Ka6 31. a4 b6 32. Qb5+ Kb7 33. Qxd5+ Kc7
34. g3, and again white should win with good technique, though this again will
take much time.
(F). Or if, 23. ... Kf7 24. Ng5+ Ke7 25. Qxe5 Qb6 26. Nxe6 Qxe6 27. Rc7+ Kd8
28. Qxe6 Kxc7, is a transposition into variation (E) just given.
(G). Or if, 23. ... Kf7 24. Ng5+ Ke7 25. Qxe5 Qb6 26. Nxe6 Rg8 27. Ng5+ Kd7 28.
Qxd5+ Qd6 29. Qf7+ Qe7 30. Rc7+ Kxc7 31. Qxe7+, white has a decisive material
advantage.
(H). Or if, 23. ... Kf7 24. Ng5+ Ke7 25. Qxe5 Qb6 26. Nxe6 Rg8 27. Ng5+ Kd7 28.
Qxd5+ Ke7 29. Re1+ Kf6 30. Qf7+ Kxg5 31. Re5+, and white has three different
mates, if, 31. ... Kh6 32. Rh5+ is mate, or, 31. ... Kh4 32. Qh5+ is mate, or,
31. ... Kg4 32. Qf3+ Kh4 33. Rh5+ is mate.
(I). Or if, 23. ... Kf7 24. Ng5+ Ke7 25. Qxe5 Qb6 26. Nxe6 Rg8 27. Ng5+ Kf8 28.
Nxh7+ Kf7 29. Rc7+ Kg6 30. Qg5+ is mate.
(J). Or if, 23. ... Kf7 24. Ng5+ Ke7 25. Qxe5 Qb6 26. Nxe6 Rg8 27. Ng5+ Kf8 28.
Nxh7+ Kf7 29. Rc7+ Qxc7 30. Qxc7+ Kg6 31. Qg3+ Kxh7 32. Qxh3+ Kg6 33. Qe6+ Kh7
34. Qxd5, and white has a decisive advantage.
(K). Or if, 23. ... Kf7 24. Ng5+ Ke7 25. Qxe5 Qb6 26. Nxe6 Rg8 27. Rc7+ Ke8 28.
Ng7+ Kd8 29. Qe7+ mate, looks useful.
There will of course be more lines to discover, happy hunting.
Apologies if there are tactical oversights in any of the above, it all came
from an aging unreliable old-fashioned bio-degradable analytical engine closer
to Cabbage than Babbage. ||
24. Qxg4+
| This capture deflects the white queen onto light squares while the black king
is about to hide on the dark square corner, away from all the nasty threats
proposed in the previous comments. And considering all the threats seemed to be
solely in white's favour, perhaps a donation of a bishop to evade the worst is
not such a high price to pay? ||
24. ... Kh8
25. Ng5
| Another interesting shot introduced during the coaching was the
crazy-looking, 25. Qd7, abandoning the white e4 knight to whatever fate black
chooses. The greedy, 25. ... dxe4, is met with, 26. Rc7, threatening two mates
with, Qg7+, or, Qxh7+. The only way to stop these twin horrors is, 26. ...
Qxc7, but after, 27. Qxc7 exd4 28. Qe5+ Kg8 29. Qxd4, and white is still
fighting.
Black can avoid all this, after, 25. Qd7 Qb6 26. Rc7 Qg6, the black queen
switch to the kingside prevents immediate ruin and also cheekily threatens a
mate of her own on the g2 square, almost certainly proving the never-quoted
maxim: "Sometimes the best form of attack is defence." Once the black queen
guards all on the g6 square, white can try, 27. Ng5, but after, 27. ... h6 28.
Nxh3 Rad8 29. Qa4 exd4, the passed black d-pawn is ready to keep advancing,
black must be winning here.
An alternate line for white which doesn't quite work is, 25. Qd7 Qb6 26. Rc7
Qg6 27. Ng5 h6 28. Qh7+ Qxh7 29. Nxh7 Rg8 30. Nf6 Rxg2+ 31. Kh1 Rg7, preventing
that white mate threat of, Rh7+, and black has also gained a decisive material
advantage on the way. ||
25. ... Qd2
| A powerful move which takes the sting out of the white attack. The white c1
rook is attacked and there is now a double attack against the undefended white
f2 pawn. ||
26. Rc7
| White might as well try for something in the far side of the board, you never
know if the opponent will find the best continuation. Going defensive is
depressing, 26. Rf1 hxg2 27. Kxg2 Qf4 28. Qh5 Qf5, and the black queen again
saves the day after which black will consolidate the kingside before starting
to push white back. ||
26. ... Qxf2+
| Mistakes are just sitting there waiting to happen. The materialistic, 26. ...
Rg8, trying to pin and win the white g5 knight, allows, 27. Nf7+ mate. ||
27. Kh2 Qxg2+
28. Qxg2 hxg2
| The liquidation has given black a decisive material advantage, no relaxation
yet though, there is just one last white trick to be appreciated and avoided.
||
29. dxe5
| White is hoping the combined forces of 7th rank rook, active knight and
passed e-pawn can create something from nothing much. ||
29. ... Rac8
| Forcing the white rook out of the way to allow a 7th rank invasion of his
own. Once the black g2 pawn is protected there will be a very strong black
threat which white must counter. ||
30. Rxb7
| White refrains from capturing with, 30. Rxh7+, in order to keep a sneaky trap
available. The idea is, Nxh7, then retreat the knight to f6 where it is
supported by the white e5 pawn, and white will have amazingly conjured up a
threat of, Rh7+ mate. ||
30. ... Rc2
| Black now sets up the threat of, Rf1, and, pawn g1=Q+, winning. White must
immediately prevent this, which means the optimistic plan of, Nxh7, with, Nf6,
is too slow and has to be abandoned. ||
31. Nf7+
| The knight blocks the f-file, and also manages to create some possibilities
which black must make sure remain confined to the notes. ||
31. ... Kg7
| Apparently stepping into a discovered check, but careful examination reveals
there are no useful knight moves which can create problems for black. Had the
white knight f7+ invasion actually contained venom, then black could simply cut
and run for a draw by repetition with, 31. ... Kg8 32. Nh6+ Kh8 33. Nf7+ Kg8
34. Nh6+, and a firm handshake with mutual smiles of relief. ||
32. e6
| White now has a 7th rank rook, a very active knight and a 6th rank pawn which
has to be contained by just a black rook and king. Should be enough, but take
care, this amount of white activity should create threats needing to be
prevented from becoming reality. ||
32. ... Kf6
| White now makes one last attempt to pull a rabbit from the hat. ||
33. e7
| White is offering the f7 knight, black has four replies to sift through:
(A). If, 33. ... Rxf7 34. e8=Q Rxb7 35. Qf8+, is uninspiring, analysis should
stop here and search for something better, and if there is nothing better in
the other first move options, then come back to this line for further analysis.
(B). Or if, 33. ... Kxf7 34. exf8=Q+ Kxf8 35. Rxh7 Rxb2 36. Rxa7, again
uninspiring, leave alone and return for further analysis only if the remaining
first move options find nothing better.
(C). Or if, 33. ... Rg8 34. Nd6 g1=Q+ 35. Kh3 Rh2+ mate, is acceptable, this
will do, but on a point of principle, can this idea be refined to be more
precise?
White might lengthen matters in this variation with, 33. ... Rg8 34. Kg1 Rc1+
35. Kf2 g1=Q+, and the mating chase takes a few more moves.
(D). Or if, 33. ... g1=Q+ 34. Kxg1 Rg8+ 35. Kh1 Kxf7, is clearly winning, but
doesn't look as efficient as variation (C), as no immediate mating chase is
available.
We guess we all know what Grand Master is about to play, right? ||
33. ... g1=Q+
| Perhaps, 33. ... Rg8 34. e8=N+ Rxe8, was available for the sake of annoyance,
but black still has the unstoppable plan of hitting the white back rank with,
Re1, and then, g1=Q+, winning. ||
34. Kxg1 Rg8+
White resigns, 0-1
