This line from the Leningrad System still remains playable for
Black. The most frequent replies 9.Nd2
and 9.Qd3
are hardly a challenge to it; the most interesting is the
exchange sacrifice 9.b3, but there is no need to accept it. |

After 3.Nc3
the option of d2-d4 remains open and if Black wants a
Sveshnikov, he must reply 3...Nf6;
after 4.Bb5
White then plays a sort of Rossolimo plus
Nc3/Nf6.
According to Leonid Kritz he achieves a paper-thin advantage in
the variation with 4...g6.

In the Apollo Variation which is dealt with, the similarity to
the Scheveningen System cannot be overlooked. But the slight
differences tend to favour Black and so what we have here is not
a critical variation. |

Liviu-Dieter Nisipeanu has had a few nice successes with 7.Nde2.
In his article the author presents a detailed analysis of all
the lines. Usually the structures which occur are less typical
than those in other lines of the Najdorf. |

In the second and final part of his repertoire for White based
on 7.Bb3
Igor Stohl investigates above all the moves 7...Nc6
and 7...Be7
as well as 7...cxd4, with their many transpositions. |

The same position is also reached after 5...h6 6.Bh4
dxc4 7.e4 g5 8.Bg3
b5 9.e5. So if one can make the variation playable, it will form
a weapon against two different systems at the same time. Martin
Breutigam shows that promising positions can be reached. |

in the side lines 8...N7b6
and 8...Bb4
9.Rc1

This side variation has above all been played successfully by
top Chinese player Bu Xiangzhi. There may be no way to prove
conclusively an opening advantage for White, but most players
are content enough with a little pressure. |

White tries to prove that compared with the 5.Qb3

is not so well placed. Perhaps it is then possible to get a
mini-advantage. |

In the side variation 7...e6 too, you get what is mostly there
for Black in the Schlechter Variation: a playable position which
is almost level. |

In the position in the diagram our author examines the moves
6...Bxd2+
and 6...Be7.
Although something can be said in favour of the exchange, Mihail
Marin does prefer the retreat. It is not easy for White to
obtain an advantage. |

White plays 8.h3, because it is always a useful move and then
unlike with 8.e4 the line 8...a6 would be favourable (9.dxe5
dxe5 10.Be3!).
But the sequence of moves which leads to the diagram seems to
give Black sufficient play. |

With this setup, which is related to the Averbakh System, White
is planning an immediate kingside advance by means of g2-g4; the
development of the
Ng1
is temporarily delayed. |
