Indirect knight trade

by Oliver Reeh
7/29/2016 – Tactics can seem deceptively simple, particularly when seeing an engine analysing grandmaster games. Strange, however, how difficult it is to find the right move and to calculate variations properly when playing yourself. It is easier if you solve tactical puzzles regularly. In the ChessBase Magazine and his tactics column Oliver Reeh helps you to do so.

Opening surveys

Havasi: Reti Opening A07
1.Nf3 d5 2.g3 c6 3.Bg2 Bf5

 

In the second part of his suggested repertoire based on 3...Bf5 Gergö Havasi investigates white setups with d3. In the starting position White can prepare the advance e2-e4 or first play c4. Black generally equalises.

 

Breutigam: Reti Opening A09
1.Nf3 d5 2.c4 d4 3.b4 f6 4.Na3

 

 

Although Black should theoretically have no problems with the knight move, the statistics show a high success rate for White. In Martin Breutigam’s article the alternatives to 3...f6 are also looked at.

 

Iotov: English Opening A21
1.c4 e5 2.
Nc3 d6

 

The move 2...d6 is linked to a simple plan: ...f5, ...Be7 and ...Nf6; as long as ...Nc6 has not been played, ...c6 (more rarely ...c5) also remains an option. White can play with or without d2-d4, but according to Valentin Iotov he should not be able to get much out of it.

Postny: English Opening A29
1.c4 e5 2.
Nc3 Nf6 3.Nf3 Nc6 4.g3 Bb4 5.Nd5 e4 6.Nh4 0-0 7.Bg2 d6

 

With 5...e4 (instead of 5...Bc5) Black injects some sharpness into the opening. At the candidates tournament in Moscow there were successes for both sides. According to Evgeny Postny, however, the balance should not be disturbed.

Terekhov: Sicilian Defence B48
1.e4 c5 2.
Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Qc7 6.Be3 a6 7.Qd2 Nf6 8.0-0-0 Be7 9.f3 b5 10.g4

 

From the diagram Black can play the “old variation” 10...0-0 or with 10...Nxd4 choose the “new variation”. In his very extensive article Andrey Terekhov examines both and also sets a few test exercises.

Szabo: Sicilian Defence B76
1.e4 c5 2.
Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 0-0 8.Qd2 Nc6 9.0-0-0 Bd7 10.g4 Rc8

 

Anyone not wishing to play 9...d5, can choose the move order which leads to the diagram. As Krisztian Szabo shows in his article, by doing so Black takes a great risk. With best play on both sides White can certainly gain an advantage.

Petrov: Sicilian Defence B82
1.e4 c5 2.
Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.f4 e6 7.Bd3

 

Neither 6.f4 nor 7.Bd3 is very popular, but as Marian Petrov demonstrates in his contribution, Black needs to know what he is doing if he is not to rapidly fall behind. Probably 7...Nbd7 is the best reply.

Gavrikov: Sicilian Defence B85
1.e4 c5 2.
Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6 6.Be2 a6 7.0-0 Be7 8.f4 0-0 9.Be3 Qc7 10.a4 Nc6 11.Kh1 Re8 12.Bf3 Na5

 

According to Viktor Gavrikov Black can equalise with 12...Na5; he is planning ...Nc4 and ...e5. The knight move has been slightly less analysed to death than e.g.12...Rb8 and 12...Bf8, but nevertheless leads to typical Scheveningen positions.

Bronznik: Chigorin Defence D07
1.d4 d5 2.c4
Nc6 3.Nf3 Bg4 4.Nc3 e6

 

In the 3rd part of his series on the Chigorin Defence, Valeri Bronznik examines two queen moves which are intended to exploit the absence of the opposing light-squared bishop from the queenside: 5.Qa4 and 5.cxd5 exd5 6.Qb3. Black needs to know what he is doing and play accurately.

Ris: Queen's Gambit D24
1.d4 d5 2.c4 e6 3.
Nf3 Nf6 4.Nc3 dxc4 5.e4 Bb4 6.Bxc4 Nxe4 7.0-0

 

The main line of the Vienna Variation (6.Bg5) has been analysed to great depth; the gambit 6.Bxc4 is a viable alternative. Robert Ris cannot prove an advantage for White, but nor does he see how Black should safely equalise.

Marin: Semi-Slav D45
1.d4 d5 2.c4 e6 3.
Nc3 c6 4.Nf3 Nf6 5.e3 Nbd7 6.Qc2 Bd6 7.b3 0-0 8.Be2

 

This time Mihail Marin examines variations in which Black plays ...e5 – either immediately or after preparatory moves. The judgement of our Romanian author is a cautious one: he cannot say definitely that there is an advantage for White, but he would rather have the white pieces.

Kuzmin: Queen's Gambit D63
1.d4 d5 2.c4 e6 3.
Nf3 Nf3 4.Nc3 Be7 5.Bg5 0-0 6.e3 h6 7.Bh4 Nbd7 8.Rc1 c5

 

It is slightly surprising that Black is able to play 8...c5 at this juncture. Alexey Kuzmin calls it the Radulski Variation because the Bulgarian grandmaster who passed away at an early age (1972-2013) played this way. But in the meantime Kramnik too has adopted the variation in his repertoire.

Krasenkow: Grünfeld Defence D85
1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Bb5+ c6 8.Ba4 0-0

 

Michal Krasenkow introduces an easy to learn plan against the early check by the white bishop. The Polish grandmaster bases this on typical Grünfeld moves, which can easily be assimilated
