Double rooks and double threats

by Karsten Müller
9/30/2014 – Chess enjoys the reputation of being a logical game, one reason why the cold calculating power of the computer prevails against the human mind. However, in chess 1+1 does not always equal two. For instance, in double rook endgames the two rooks often can create more threats in one game than one rook could in two. Dangerous double threats!

Stohl: English Defence A18
1.c4 Nf6 2.Nc3 e6 3.e4 d5 4.e5 d4 5.exf6 dxc3 6.bxc3 Qxf6

As Igor Stohl demonstrates, the Mikenas-Flohr Variation of the English Defence is really reliable from Black’s point of view, but at first there is a struggle for equality. Even Aronian, the greatest expert with the white pieces, came to grief when he played the variation with Black against Grischuk.


Rotstein: Old Indian Defence A53
1.d4 Nf6 2.c4 d6 3.Nc3 Bf5 4.Nf3 c6

According to the analyses of Arkadij Rotstein White cannot, just as he is unable to do with 4.f3 e5 (see CBM 161), lay claim to a simple advantage after 4.Nf3 c6. Above all, 5.Nh4 Bg6!? proves to be surprisingly playable for Black.

Antic: Benoni A62
1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.Nf3 g6 7.g3 Bg7 8.Bg2 0-0 9.0-0 a6 10.a4 Re8 11.Bf4

The white bishop move is somewhat annoying for Black, since the natural developing move 11...Nbd7 is now excluded. In his article Dejan Antic analyses the two popular replies 11...h6 and 11...Nh5, but he believes that only the knight move offers certain chances for equality.

Havasi: Modern Defence B06
1.e4 g6 2.d4 Bg7 3.Nc3 d6 4.f4 a6 5.Nf3

It is not at all rare to see this variation with ...a6. Gergö Havasi investigates above all 5...Nd7, since he has reserved the main variation 5...b5 for his next article. White should achieve a comfortable game with natural developing moves – developing the bishops.

Krasenkow: Sicilian Defence B25
1.e4 c5 2.Nc3

Michal Krasenkow thinks that the Closed Sicilian is very playable at amateur level. In his article he presents a repertoire for White, just as he played himself till reaching a playing strength of around 2400.

Postny: Sicilian Defence B46
1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 a6 6.Nxc6 bxc6 7.Bd3 d5 8.0-0 Nf6 9.Re1 Be7 10.e5 Nd7 11.Qg4

The variation attracted the attention of Evgeny Postny because it was recently played by Fabiano Caruana – both with White and with Black. There is a trend away from 11...g6 to 11...¢f8. At the moment the variation appears to be under development and there are as yet no certainties.

Szabo: Sicilian Defence B90
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nb3 Be6 8.f3 h5 9.Nd5 Bxd5 10.exd5 Nbd7 11.Qd2 g6 12.Be2

The position in this diagram has been seen recently on several top level boards. The continuations 12...Bg7 and 12...Qc7 are up for discussion. As Krisztian Szabo shows, as well as a knowledge of variations one should also master a few tricks and manoeuvres.

Müller: King's Gambit C34
1.e4 e5 2.f4 exf4 3.Nf3

In the first part of his repertoire for White with the King’s Gambit Karsten Müller acquaints you with his fundamental idea. It is a setup with Nc3, d4 and g3 and is called the Quaade Gambit (or the Quaade setup). It works excellently against Fischer’s Defence 3...d6 and Becker’s Defence 3...h6.

Breder: Ruy Lopez Four Knights C48
1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bb5 Nd4

The article by Dennis Breder focusses after 4...Nd4 on the reply 5.Ba4. It should be followed by 5...c6 and, as our author shows, in many lines Black can even hope for more than mere equality.

Kuzmin: Queen's Pawn Game D00
1.d4 d5 2.Nc3 Nf6 3.Bf4

Alexey Kuzmin refers in his article to the games of Baadur Jobava, who has recently been employing this variation successfully. Jobava’s special variation comes after the most played move 3...Bf5 in the form of 4.f3 e6 5.g4 Bg6 6.h4.

Marin: Nimzo Indian Defence E53
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 0-0 5.Bd3 c5 6.Nf3 b6 7.0-0 Bb7 8.Na4

The line with ...c5 is very solid and involves a substantial amount of theory, but Mihail Marin manages, starting with 8.Na4, to show how White can set his opponent problems and aim for an advantage.
