Petroff Defence

-release the e-file for the rook with

the multi-purpose move Qd4 which

also controls a1-h8 diagonal

-play f2-f4

-clear the e file in order to maintain

the nemy king in the center

-use the lack of coordination in

Black's camp. ;

B) 4...Ne4 5.Qxd4

B1) 5...f5

Black wants to sharpen the game

as in the Schliemann Defence or

the Latvian Gambit. White has to

keep his coolness and to trust his

positional advantages:

-better control over the central

squares

-better king since Black just

weakened his king's position

especially the a2-g8 diagonal.

6.Be3 Bc5 7.Qd3

B1a) 7...d6 8.Nbd2 Bxe3

9.Qxe3 d5

Once that this pawn structure

arise on the board Black's worse

minor piece is Bc8. White should

aim to unbalance the position by

exchanging the black knights for

a knight and bishop, reaching a

positin with better knight versus

bad bishop.

( 9...dxe5?! 10.0-0-0 Qf6

11.Nxe4 fxe4 12.Qxe4± )

10.Rd1

A good exmple of how White

should keep the momentum

instead of castling to quickly.

Black's central setup is suported

by d5 , so White will act

imeddiately before Black

consolidates with Be6 and c6.

0-0 11.c4 c6 12.cxd5 cxd5

1.e4 e5 2.Nf3 Nf6 3.d4

Instead of moving the knight twice with 3.

Nxe5 ,White goes for a quick

development which is the most important

feature of open games.

Nxe4

[ 3...exd4

From strategical point of view this is

White's dream. Black loses a tempo to

exchange his only central pawn, while

Nf6 will become vulnerable to a pawn

attack e4-e5. On the long run White

creates a king side pawn majority,

which unbalances the game right from

the begining, compared to the

symetrical pawn structures usually met

in Petroff Defence.

4.e5

A) 4...Qe7

After such moves White has to castle

short quickly and to tak absolute

control over the central files.

Nge5 ;

A2) 9...Ncxe5 10.Nxe5 Nxe5

11.Qe4 c6

The only move, Black has to

defend the central square d5 where

White's pieces can easily land, the

threats were Nc3-d5 or Rd1-d5.

12.Be3 Qe7 13.Rae1²

White has a huge lead in

development and more then

enough compensation for the

pawn.

To do list:

13.Bc4 Nxf2 14.Qxf2 dxc4

15.Nxc4 Qe7 16.0-0² ;

B1b) 7...Na6 8.a3 d5 9.b4

Bxe3 10.Qxe3²

Once that Black's immediate

threats were repelled White

remained with:

-a passed supported pawn on

-a better light squares bishop

-the threat to spoil Black's pawn

structure with 11.Bxa6.

To do list:

-pay attention to Black's pawn

moves a7-a5, c7-c5 and f5-f4

-try to chase Black's most active

piece Ne4

-create pressure against d5. ;

B2) 5...d5 6.exd6 Nxd6

In such positions were the central

pawns are liquidated, White has

the initiative since it has a certain

lead in development and the active

queen. If Black wants to finish his

own pieces development, it will be

usually forced to make

concessions regarding the material

balance (losing the pair of bishops)

or the pawn structure.

White should look for possibilities

to create black double pawns on

c7 and c6 or to use the weak

squares created by Black attempts

to activate his pieces.

White will use the central squares(

e4,e5,d5,d4) as activating squares

for his minor pieces especially for

the knights.

After the opening White gets a long

moves will increase th pressure

along the d-file. )

8.Qf4 Kritz,L: 'Die weiße Dame hat

auf f4 ein sehr gutes Feld gefunden,

wo sie nicht angegriffen werden

kann. Da die Bauernstruktur völlig

symmetrisch ist, hat derjenige

Vorteil, der die besser platzierten

Figuren hat, um Initiative zu

entwickeln. Das ist hier natürlich

Weiß, weil seine Springer besser

stehen.' Kritz,L: 'Weiß hat einen

kleinen Vorteil, weil seine Dame

auf f4 unantastbar steht, der

schwarze Springer auf d6 dagegen

die schwarze Entwicklung stört.'

aiming for.

15.Nd5 Rfe8 16.Be3 Rab8

17.Nxe7+ Qxe7 18.b3²

One of White's goals in this

position is to trade all the

pieces and to win the pawn

endgame by placing Kc5. His

task is easier now since the

bishop is userior to the knight in

positions with pawns on both

wings. )

11.Nxf5 Qxf5 12.Qxf5 Nxf5

13.Bd3 Nfd4 14.Be3 0-0-0

15.0-0-0²

To do list:

-bring the undeveloped rook on

-place the bishops on adjacent

diagonals on e4 & e3

- keep a rook on the board as

play coordinating piece

-restrict the knights activity by

slowly advancing the pawn

-create weaknesses in the

enemy camp as the bishops

have better mobility. ;

After the opening White gets a

next moves will increase th

pressure along the d-file. ;

B2b) 8...Nf5!

A natural move preparing the

development of Bf8 discovered

by Karpov's coach Igor Zaitsev.

9.Bb5 Bd6 10.Qe4+

This is an improvment of

Kasparov's next idea.

pair of bishops.

Rdf8 16.Bc3

The pawn structure is

symetrical, but White has a

better pieces setup. In the

following line I tried to give an

exmple of how White should

use the initiative and to get a

long term postional advantage

like the pair of bishops.

h6 17.Ne4 f6

In order to restrict the activty of

Bc3 and to release Nf5.

18.Rxd7 Kxd7 19.g4 Nd6

defense against the strong

threats Ne6 and Bxc6.

15...Nh6 16.h3²

To do list:

-restrict the activty of Nh6

-try to gain one of the pawns h7

or f7 with the help of the threats

Bd3 & Ng5

-create a free pawn on the king

side using threts against Nh6. ;

B2c) 8...Be7 9.Be3 Be6

From now on White will focus on

exchanging Nf3 for Be6 in good

conditions. For this purpose the

long castle is indicated since

White's attack on the king side

will gain momentum in the

absnce of Black's light squares

bishop.

At first sight it seems like a

the queen side , but White

has the lead in

development and it will be

able to exploit the weak

dark squares around the

black king. For this goal it

has to complete the knight's

manover Nf3-g5-e4-f6-d5.
