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

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 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

 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
21.  Rfa1                                Rae8
22.  Rxa7
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.

1    e4              c5
2   Nf3             Nc6

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?!

3     d4                cxd4
4     Nxd4            e6
5     Nc3              Qc7
6     g3                 a6
7     Bg2              Nf6
8.    0-0               d6
9     Re1              Bd7
10   Nxc6            bxc6

If 10 ,,,Bxc6  11  Nd5  Qd8  12  Bg5  with pressure. the weakening of Black's Queenside pawns has begun.

11   Na4             e5
12   c4                --

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.

12   ---               Be7

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.

15   Bg5             Be7

15 ..Bb4 can be satisfactorily met by 16 Re3  Ng4  17  Rd3  Be6 18  h3  etc.

16   Qc2             h6

17   Be3             Rab8
18   Rac1           Rfd8
19   h3               Nh7
20   Bc5             Be8

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.

21  Red1            Rxd1

22  Rxd1            Ng5
23  Bxe7            Qxe7
24  Nc5              Ne6
25  Nxe6            -----

Better than 25. Nxa6 Rb6  26  Bf1  Nd4  with sufficient play for the pawn.

25  ----              Qxe6
26  b3                b3
27  Qc3             -----

Putting pressure on the e-pawn with the intention of following up with Bf1 attacking the a-pawn. Black's defensive problem is very difficult.

28  h4               f6
29  Rd3             Kh7

Unsatisfactory is 29 ...c5  on account of 30  Rd5  c4  31  bxc4  Bf7  32 c5  Rb1+  33Kh2  Bxd5  34  exd5, and the two passed pawns would win easily.

30   Bh3            Bg6

31   Rd7            ----

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.
31   ----            Qf8
32   Qxc6         Rxe4

If 32 ...Bxe4  33  Qxa6  Qc5  34  Qxf6   Qc1+  35  Bf1   and wins

33   Qxa6         Re1
34   Kh2           f5

No relief is offered by 34 ... Be4   35  Bg2  Bxg2   36  Kxg2   Qb4   37  Qxf6  Qe4+   38  f3  Qc2  39  Kh3  Rh1  40  Kg4  and wins.

35  Rd6           Bh5
Finally Black Resigns.
