Petrov's Defence

In the Russian Defense is an opening of the chess game; it is one of the open-ended games.

The Russian defense begins with the moves:

1 e2- e4 e7 - e5 2 Sg1 -f3 - f6 Ng8

After the simple 3 Nb1 - c3 they can pass on the triple jumper game into the Four Knights Game. When black 3 ... Nc6 pulls - - the Two Knights game at reunification After 3 Lf1 - c4 to variants of the game and give runners.

Background

The Russian defense was named after the two Russian chess masters Petrov (1794-1867) and Jaenisch ( 1813-1872 ). These have performed the first accurate study of this opening. The Russian defense has always been considered solid, forcing blacks but in many playing to great accuracy. It is, however, already ausanalysiert far by their popularity in the current world leaders and includes, for example the standard repertoire of Vladimir Kramnik, Michael Adams, Viswanathan Anand and was - in its active time - one of the main weapons of the long-standing world chess champion Anatoly Karpov.

Main variants

• The proximal third Sf3xe5 (ECO code C42 ) is the Classical System of the Russian defense. The Zwischenzug 3 ... d7 - d6 leads to 4 Ne5 -f3 Sf6xe4 often further 5 d2 -d4 d6 -d5 6 Lf1 -d3 Bf8 - e7 ( Black avoids a potential tying his knight on e4. The runners are later depending on the situation, the fields or f6 h4 available. Alternatively, if more risky because it is sharper 6 ... Bd6 playable. ) 7 0-0 Sb8 - c6. 8 c2 - c4 Nc6 - b4 9 Bd3 - e2 10 a2 -a3 0-0 or 8 Tf1 - e1 Bc8 - g4 9 c2 - c4 now undermined the knight on e4.

From the year 2000 5 Nb1 - c3 be established?

This variant has the advantage that white to 5 ... Se4xc3 6 d2xc3 free figure game for the farmer gets double and can quickly occupy the central lines with its heavy figures. White should place his knight to d4, but before play Lf4 because the aggressive black knight to Dd2 and 0-0-0 then can no longer sell to the c-pawn, but would leave hike his knight after e6. White thereby inhibits c7/d6 the black pawn complex. 6 ... Bf8 - e7 7 Lc1 - f4 0-0 8 Dd1 -d2 - d7 Sb8 9 0-0-0 Sd7 c5 10 Nf3 -d4 describes this. 7 Lc1 -e3 0-0 8 Dd1 -d2 - d7 Sb8 9 0-0-0 Sd7 e5 10 h2 - h4 oriented on white pawn storm on the kingside.

• The system introduced by Wilhelm Steinitz 3 d2 -d4 (ECO code C43 ) has the answers ... 3 4 Sf6xe4 Lf1 -d3 d7 -d5 5 Sf3xe5 Bf8 - d6 6 0-0 0-0 and 3 e4 e5 4 e5xd4 ... Nf6 -e4 d7 -d5 5 Dd1xd4 6 e5xd6 Se4xd6.

Original, though double-edged, is the gambit introduced by John Cochrane and further developed by David Bronstein and Alvis Vītoliņš

• 3 Sf3xe5 d7 - d6 4 Se5xf7 Ke8xf7 5 d2 -d4

And White obtained for the material loss ( knight against two farmers ) took the initiative in the center and attack prospects due to the poor king position of black.

Opening Traps

An early letdown

This typical opening trap leads to an early game loss:

3 Sf3xe5 Sf6xe4?

Man on a Ledge train, which was played by the Austrian International Master Friedrich Volkmann many times before. Black must play exactly 4 Dd1 - e2, immediately loses example

4 ... Ne4 - f6?

Because after 5 Ne5 - c6 Black must give his lady. The right train is 4 ... Qd8 - e7. After 5 De2xe4 d7 - d6 Black will regain the Springer. 3 Sf3xe5 Sf6xe4? is then only a dubious pawn sacrifice.
