Spielmann Attack : Pawn Sacrifice

Pin It
Speilmann Attack  :  Pawn Sacrifice
Recently I come across the game in which  White played 5 e4 instead of 5 Nd2 and latter on 6 e4 to chase away the Bishop.

1  d4  Nf6  2 Nf3  c5  3 d5  d6  4 Nc3  Bf5  5 e4!?
Normally played 5 Nd2 g5!  6 e4  Bg6

5 ...Nxe4  6 Qd3



6... Qa5?!

Bad is 6 ... Ng3? 7 Qb5+  After  6 Nxc3  7  Qxf5  8  Qd3  Na4  9 Qb3  Nb6  10  a4 

White has some compensation for the pawn.
7 Ng5!  c4  8  Qf3 

8  Qxc4  Nxc3 is fine for Black.

8 ...Nxc3  9  Qxf5!  Ne4+

The only move in view of the threats on f7 and c8

10  c3 Nxg5  11  Qc8 +  Qd8  12  Qxb7  Nd7  13  Bxg5  Rb8  14  Qxa7  Rxb2






15  Bxc4


Above are the forced moves

15 0-0-0 with an attack was indicated by Kogan, but Drazic move is simpler. White's position is more or less winning. Black should especially investigate 6... c4 which looks like his best bet.

15 ...f6?!  16  Be6  Ne5  17 0-0  Rb8  18  Be2  g6

Black has difficulties finishing his development, he is a pawn down, and to make matters worse his opponent has the simple plan to push his a-pawn all the way

Gruenfeld Defence.

Pin It
M. Taimanov   :   W. Uhlmann
Belgrade  -  1970

1  d4   Nf6   2  c4   g6   3   Nc3   d5   4  Bg5
It is a long-discarded line.

4 ... Ne4   5  Bh4
A relatively recent idea that seems to give Black difficulty. More usual is 5 cxd5  Nxg5  6  h4  Ne4  7  Nxe4  Qxd5  8  Nc3  Qh5 with even chances.

5 ... c5

Also playable 5 ...Nxc3  6  bxc3  c6

6 cxd5   Nxc3   7  bxc3  Qxd5  8  e3  cxd4

In view of what happens in this game, 8 ...Bg7  or  8 ... Nc6!?  ought to be considered.

9 Qxd4

By attacking Black's queen and rook, White forces the exchange of queens. The alternative 9 cxd4 ( 9 exd4?  Qe4+  and 10 ...Qxa4)  allows Black the possibility of capitalizing on the absence of White's QB from the queenside. Now White can use the open queenside files and has pressure against Black's e-pawn, whereas Black's most active piece, his queen, is back in the box.

9 ...Qxd4  10 cxd4
Opening the c-file for action by his rooks. Black now has problems castling because of the pressure against his e-pawn.

10 ... Nc6   11 Bb5  Bd7  12  Nf3   Bg7  13  0-0  e6
A weaking move but necessary in order to be able to castle. If 13...0-0 Black loses his e-pawn

14  Rab1  0-0  15  Nd2!

White's threat is Ne4, aiming at c5, d6, and especially f6 with a strategically won game. To prevent this Black weakens himself further.

15 ... f5

No doubt played reluctantly, for his e-pawn is now very weak and his position precarious. A better try is 15 ... h6  16  Be2  Na5  but after 17 Ne4  White's advantage is clear. The text move prevents Ne4  forever, but it is a major concession.

16  Nb3  b6  17  Rfc1  Rac8  18  Ba6  Rce8  19  Bb7  Nd8



The diagram clearly displays that the c-file is open and White has clear control over it. White can also form a battery on the c-file to exploit the 7th rank benefit. Also, the White Bishop on h4 square has a clear control over the Dark Diagonal.

20  Rc7  Rf7  21  Ba6  Ba4  22  Rbc1  Bf8  23  R1c4! 

Not so useful  23 Bc8  Bd6  24  Rxf7  ( Bxd8?  Bxc7  25  Bxc7  Rxc8)  24 ... Kxf7

23  ...Rxc7  24  Rxc7  Nc6  25  Bc4

Black's e-pawn cannot be saved. The crushing threats are 26 Rc8  wining the e-pawn and 26 Bf6, with d5 in the air.

25  ...Bg7 
26 Rc8

Winning a pawn by force. Black was aware of this possibility but could do nothing to prevent it.

26 ...Rxc8  27  Bxe6+  Kf8  28  Bxc8 

The resulting endgame presents some technical difficulties for White, whose extra pawn is counterbalanced somewhat by Black's potential passed pawn on the queenside and more active king.

28 ...Nb4  29  Nc1  Kf7  30  Bg3  Bf8  31  Bb7  Ke6  32  Bb8  Kd7  33  Bf3 

Not 33 Bxa7  Kc7  34  Bf3  trapping the queen Bishop.

33  ...Bb5  34  Bd1  a5  35  a4  Bc4  36  g4 ;

Attempting to weaken Black's kingside pawn structure and to develop two passed pawns in the cneter. Black therefore avoids 36 ...fxg4  but his kingside pawns become weaker.

36 ...b5  37  gxf5  gxf5  38 Be5  Nc6  39  Bh8  Ba3  axb5

1  e4  c5   2   Na3  Vadim Zviagintsev against Alexander Khalifman in Moscow Ch Rus 2005 game brought Night to the edge. Such move is always creatisized. The Basic rule always suggest to bring the pieces towards the centre.

The diagram clearly shows that the White Knight on a3 is weak and hence White plays 15 c4 to improve the bad knights strength.

Also The White pawn on e5 is well protected by a Rook-Queen Battery, Also, e5 square is under the control of White e4-e5 possiblility also there and it will become a threat.

Sicilian Najdorf : Classical Variation

The 'Najdorf' was first played by Czech International Master karel Opocensky. It was Meguel , in late 1940s, devoted the most effort to investigating and popularizing the line and hence the openign took his name. Other strong players soon recognized the strength of this variation, and it quickly became on of the Black's most fashionable defences. During 1960s it was Popularized by Fischer, and nowadays it is possibly the most fashinable 'defence' to 1 e4 at the highest level, being played by Gelfand, Anand, Shirov, Topalov, Ivanchuk, Svidler, amongst others.

Modern Chess and Its development.

Pin It
The pawns are the soul of chess, creating conditions for both attack and defence; the win or the loss of a game depends on the good or bad position of the pawns. disturbed even his contemporaries.
Philidor

Philidor was of the opinion that one should be like a skilled worker while handling pawns development. He even given importance and priority to the development of pawns than the development of pieces. Adolf Anderson preferred gambits such as Evans Gambit and the King's Gambit which he made emenently respectable. In these openings White offers material to gain time and space. Even pawn sacrifices to help the coordination of pieces were much more soundly based in Anderssens games. Paul Morphy gave importance to the strategic principles of the open game especially gambit openings. He adopted a style in which pieces are developed by opening files and diagonals. Mikhail Ivanovich took the open game to its highest point of perfection. Chigorin contributed a great deal to the theory of certain gambits such as Evans gambit, Kings gambit. He developed new ideas for Black's defence to the Ruy Lopez and these forms the basis of a number of well nown defensive systems. In England chess took another direction, with Howard Staunton as the leading exponent of the English style. Staunton's main concern was to obtain a sound position, and he was content with slight advantage. The development of modern chess strategy begins with the work of Wilhelm Steinitz (1836-1900) For thirty years hes was considered the strongest player in the world. His work began an era in which chess became a scientific game. He was a great subscriber of the Italian school of thought. Later on he started finding new paths. Lasker summerized his views as,
1. There is an 'equilibrium of position'.
2. Sharp attacks can only be attempted when this equilibrium is disturbed, never before.
3. It is fundamental that attacks must only be aimed at the 'weak points' in the enemy position.
4. The defence must be conducted with the utmost economy of means and must not tie down pieces
     unnecessarily.

 He also signified the inportance of the following points.

1.     Weak points
2.     Doubled and isolated pawns,
3.     Explained the value of the Queen side pawn majority.
4.    The superiority of the Bishop pair in open positions.
5.     Pawns protecting the castled king are best at their original position.
6.    He stressed the nedd for a  blocked centre when attacking on the wing. Opening theory was
       enriched by many of his ideas. There are some weaknesses in Steniz's theory but the vast
       contribution he made to the game of chess made him as the founder of modern chess theory. Steniz's successor Dr Siegbert Tarrasch (1862-1934) detailed the chess principles in his books Die Moderne Schachpartie ( Modern Chess) and Dreihumdert Schachpartien ( 300 games of chess ) Emanual Lasker (1868-1941) extended the principles of steintiz giveing a precision. Tarrach's fundamental ideas about 'economy' in chess thinkign, and simplification of all problems which occur in a game, were borught to the highest peak of perfection by the Fosi Raul Capablanca (1888-1942). Richard Reti, Aron Nimzowitsch and Saviely tartakower, the hypermoderns, took as their starting point the teachings of Steinitz which they supplemented by several important strategic principles an above all by a new concept of the struggle for the centre. They demonstrated that the pawn centre is not always necessarily advantageous and may even present a serious weakness if immobile and exposed to flank attacks.

In his book 'My System' Nimzowitsch explained further strategic ideas concerned with the ,

1.   Blockade
2.   Pawn chain and the manoeuvre.

Hypermoderns gave new life to the development of the game. Later on some of their priciples led them into adopting many bizarre, unnatural and disadvantageous set ups, resulting in unpleasant defeats.

Dr. Alexander Alekhine (1892-1946) made a deep and thorough study of the teachings of Steinitz and revealed an accomplished playing technique along with an outstanding positional insight.

There are contributions by different chess players and genius till Robert Fischer. The chess player should have a knowledge of all these theories and study the contribution to the development of modern chess.

File and Rank : Its control.

Pin It
There are eight files, eight ranks, twenty six diagonals, and trillions of permutations and combinations. This means that your ultimate objective, the checkmate of the enemy king can be achieved in innumerable ways.

Kings Indian Defense

S. Reshevsky                       H. Westerinen

1.  d4                                         Nf6
2.  c4                                          g6
3.  g3                                         Bg7
4.  Bg2                                       0-0
5.  Nc3                                       d6
6.  Nf3                                       Nc6
7.  d5                                         -----

More usual is 7 0-0  a6  8  h3  followed by 9 e4 or 9 Be3

7  ----                                       Na5
8.  Nd5                                     c6!

A good move, which refutes White's entire setup. The point is that White is unable to win a piece with 9. b4 on account of 9 ... Nxd5! and Black's KB springs suddenly to life. Now White's KB becomes less effective and this casts suspicion on his entire system of development.

9.  0-0                                     cxd5
10. cxd5                                  Bf5

Having his knight "traped" after 11. b4 doesnot bother Black at all because he has the adequate reply 11 ...Rc8 12 Bb2  Nc4 with superior prospects.

11  Nb3

11  e4  Bg4  12  f3  Bd3  13  Qe2  Rc8  would deactivate White's KB without  improving his chances.

11  ----                                   N x b3
12  a x b3                               Qd7

With the intention of exchanging bishops by continuing ---Bh3

13.  e4                                     Bh3
14.  Qd3                                  Bxg2
15.  Kxg2                                b5!?

An interestng and enteprising move. Westerinen tries to seize the initiative on the queenside, now that he no longer has to worry about White's KB. His enterprise is commendable, but he runs the risk of giving White strong pressure on the opne lines leading to his quenside. His intention is to drive the knight from c3 where it protects white's centre.
16.  Be3                                 ----

But 16 Qxb5  Qxb5  17 Nxb5 Nxc4  18  Re1  Nc5  19  Rxe7  Nxb3 with advantage for Black.
16  ----                                    b4
17  Ne2                                   e6
18  Ra5                                   ---

This is the only means to keep up the pressure and it prepares to double rooks on the a-file.

18  ---                                    exd5
19.  exd5                                ----

White's pawn at d5, though isolated, restircts the mobility of Black's forces.

19  ----                                 Rfe8

Black's immediate problem is his 1-pawn which is exposed on an open file and under pressure from two directions. His only course is to apply counterpressure against White's d-pawn. The purpose of the text move is therefore, to play ...Re5.

20   h3                                   Re5

White now has full control of the a-file in addition he has a rook on the seventh rank, which makes it impossible for Black to build up the counterattack and , at the same time, restricts Black's mobility. White has the upper hand.

We see in this game the effect of control of an open file; ultimate occupation of the seventh rank. It is not alwyas possible or even necessary to try to open files early in the game in the vicinity of the enemy king, but control of a distant file serves the same purpose, especialy when, as in this case, the opponent has insufficient compensation.

Bad Pawns and Bad Pieces.

Pin It
It is always a dedicated judgment to advance pawns farther than needed merely to develop pieces and to control the centre. Sometimes pawns are not sufficiently advanced and may become backward and drastically reduce mobility; those advanced too far may exceed the reach of other units and thus become indefensible.




Black incurs a couple of weak, isolated pawns as the result of an opening novely by Tal. Such a purely defensive task is surely not what Black hopes for in the Sicilian Defense; but if Najdorf had chosen to avoid those weak pawns, he would have had a life less, passive position, and for Najdorf that is intolerable.

Not the Najdorf Variation! That line has developed to such an extent that it
bears little resemblance to the system popularized by Najdorf so long ago. Pehaps it no longer suits his style?!

11   Na4             e5

White's plan is clear : to further weaken Black's pawn structure on the queenside and via the open files, to attack the pawns directly.

To be considered is 12 ...c5  13  Bg5  14  Nc3  Bc6 with scarcely perceptible advantage for White, but not a hint of play for Black.

13   c3               0-0

Since 13 ... dxc5 does not win a pawn, that move would simply lose tempo.

14   cxd6           Bxd6

Black's two weak pawns, particularly the c-pawn, stifle his pieces. Not great subtlety is needed here; the pawns are clearly vulnerable targets for which Black has no discernible compensation. However, Najdorf is always dangerous, and so Tal sees no reason to complicate matters.

Because he has to tend his weak pawns, Black cannot become active. Little by little, White's pieces occupy better positions and Black's become more passive.

Obviously White's Pieces are bette placed. he has a rook on the seventh rank, Black's queen is tied to the defense of the king, and Black's Bishop is a defensive piece only. Meanwhile, Black's weak pawns are about to fall.

Tsunami In the Opening.

Pin It Once Tolemy went to Socratice and said,"Sir, I want to learn Geometry from you. I wish to learn it as fast as i can. You know I am a king and hence I do not have more time to spend on it.

On which Socratice replied, "Mr. Tolemy, always remember that life can be led through two ways one is Royal way and other is difficult way. There is an option either Royal way or difficult way. You have a choice. But as far as education is concerned there is no choice. there is only one way and that is 'difficult way' You have no option.

Dear friends, While going through the jungle of chess variations, different tactics and strategies, and Manoeuvres we have to adopt the difficult way. Very tactical devices such as discovered check, pin, fork, x-ray, clerance, double attack, blockade, sacrifice etc are employed. To learn these devices we have to follow the difficult way and not Royal way. The sacrifice is an essential element of a combination. But it is by no means every error that is punished by a combination, i.e. with the essential use of a sacrifice. An erroneous move can sometimes be refuted by a forcing manoeuvre on its own.

Mate With Two Bishops.

Pin It Sometimes we reach the situation where endgames become very tedious and we feel we should stop game here and declare draw. But playing such games and practicing for it is more interesting than any other endgames.

Here is one of the most facinating endgames. Mating with two Bishops requires the king is to be shifted to the edges of the board, not only to the edges of the board but to the corner of the board.

Is it simple to force the king to move to the corner of the board. If you think it is not possible then check it out how it works.

Once you got the idea try placing two Bishops and Kings on the board and practice it.

















1 Kf2 Kd4 2 Bf3 Kd3 3 Be5 Kd2 4 Be4 Kc1 5 Ke3!

While trying to force the king to move to the corner be careful is will have a space to move otherwise it will be a stalemate.

It is very important that the kings opposition is to be maintained every time the opponents king move.

Weak Pawns.

Pin It The pawn, wrote Philidor, is the soul of chess Although he wrote it some two hundred years ago, and although it remains valid today, many amateurs do not realize just what it means and how they can profit by understanding it.
The pawn formation that results from the opening is the Principle determinant of the further


course of the game. The position of the pawns largely indicates where the other forces are best disposed, and it is the clash of unbalanced pawn structures that makes chess a fight. that is why symmetrical pawn structures usually lead to drawish positions.

Furthermore, given the sophisticated technique of today's masters, weak pawns are excellent targets, and the loss of a single pawn can mean the loss of game. Therefore, good players avoid weak pawns assiduously.

What is a weak pawn? A pawn that is exposed to attack and also difficult to defend is weak. there are several varieties : Isolated, doubled, too advanced, retarded. An isolated pawn, because it is separated from the neighboring pawns and cannot be supported by them, requires defense by pieces. these pieces are called passive since they must function below their full potential. A doubled pawn is limited in mobility; its weakness is usually felt in the endgame because a group of pawns that includes a doubled pawn is less likely than a healthy group to produce a passed pawn. a pawn that is advanced too far runs the risk of being cut off from the rest of its army and becoming isolated. A pawn not advanced far enough can get in the way of the other pieces and may become backward and vulnerable.

Weak pawns can be tolerated in certain cases, particularly when you have, or are sure to get, equivalent compesation, like a strong attack or at least the creation of an equally weak pawn in the opponent's camp. Best, of course, is to avoid them.

Security of the KIng's Bunker.

Pin It


Pawns at their original positions are considered to cover the king best, as they protect all neighbouring squares, which makes it more difficult for the attacker to exchange pawns and break open files for his rooks.



Threat of Back Rank Weakness :

However the arangement of pawns in a line also has its drawbacks, e.g. it is frequently necessary to take into account checkmate threats through back rank weakness.














Any advance of these pawns useally weak the castling positio, and since the pawns cannot move back, this weakness is irreparable and long lasting. Take a look at the following diagram,
















The advantage of this structure consists of the fact the king has an empty h2 square to escape to a so-called hole and safe oneself in case of back rank weakness.
However, the structure has some disadvantages. The h3-pawn is a good target for tactical blows. The attacker can sacrify the piece to destroy the kings bunker.

Advance with g-pawn :

When you make a move with the g-pawn , there arises a pawn arrangement similar to the wedge. Such an advance can be both voluntary and forces. In both cases it results in a significant weakening of the f3- and h3-squares. Also, the diagonal a8-h1 and f1-h3.

However there is a fianchetto bishop on g2-square protecting the weakness, the castling position usually is quite safe. The opponent always try to exchange this piece.















Advance with f-pawn :

The f-pawn is pushed ahead no less often. In this case the g1-a7 diagonal and especialy the e2-square are weakened. Besides the pawn on f3 occupies the square which is more suitable for knight.

At the same time the placement of the pawn on f3 is a positive factor in the endgame, as it allows the king to reach the cnetre quicker.















There are situations when two pawns are advance f3 and h3. then the whole complex of squares near this king is weak. In those cases attacks along the a7-g1 and b8-h2 diagonals are especially dangerous.

Besides there is a 'hole' on the g3-square which frequently is a very convenient outpost for the opponent attacking pieces.


The pawn cover of the king can include double pawns. Which can be both rather strong and hopelessly weak

1. The doubled pawns provides a rather reliable barrier for the king. But these barriers also have their weakness.

a) When h2 pawn moves to g3-square, it weakens the H-file.

b) when f2 pawn moves to g3-squares it weakens the a7-g1 diagonal.

Doubled Isolated Pawns : The doubled isolated pawns arising after an exchange on the squares f3 or h3 are especially unpleasant for the defensive side. Such pawn are not only weak in themselve but in addition expose the g-file, the a8-h1 diagonal and the f3-square respectively the g-file and the h3- square.

2. Finally the kings pawns can also looks like a chain. such cover is considered to be very weakened too, as the a8-h1, a7-g1 and h3-f1 diagonals are easily accesible for the oponents pieces.

In both cases advanced pawns can be easily attacked by the opposite sides. On the top of that the position in the left diagram has the weakened 2nd rank.

Seven Rules of Development.

Pin It Before going to the seven rules of development we should see the attributes/elements of the chess strategy. These are ,


1. The Centre
2. Development and arrangement of pieces.
3. Pawn structure.
4. Strong and weak square and points.
5. Open lines and diagonals.
6. Advantage of the Bishops pair
7. Position of the King.


Keeping these seven elements in the mind one has to do the development of chess pieces.

The seven Rules of Development :

1. Do not make more than two or three pawn moves ( First develop your central pawns)
2. As soon as possible develop your Bishops and Knights.
3. Your pieces should occupy or attack the central squares.
4. Do not move with the same piece twice if it does not give you any direct profits.
5. Do not go for opponents pawn if it does not help the development of your pieces.
6. Do not hurry to bring out yur queen until your king has castled.
7. Develope your pieces in such a way that they prevent the development of your opponent.

All these above rules are conditional so I never call them as rules but just the guidelines.

Decoying

Pin It



The act of decoying plays important role when one piece is overworked and engaged in defending one, two or three pieces or one , two or three squares. If such piece is decoyed then the square or pieces it is defending becomes vulnerable.

Here Black Plays 1 ... Re1  2 Rx e1  Qd4+

White queen will have to capture the Black queen or Black queen will capture it and subsequently the white queen will get decoyed.


                                                      Its indirect control over the e1 square will get removed.




In this position Black queen is guarding Black Rook which is attacked by White Queen and Two Black Bishops are also defended by the Same Black Queen. If this Black Queen is deflected or decoyed the Black rook and the Bishops will become vulnerable. or defenceless.

1  Qc4+   Kb8   2  Rxd7 Black Queen is compelled to move.





White Rook on d1 is guarded by Queen on f3. Think of decoying this queen on f3.

1 .... Qc6

drawing the queen away from defending the rook at d1, and at the same time attacking the rook at b5, forced White to resign.
