Moves1.Nf3
ECOA04–A09
Named afterJohannes Zukertort

The Zukertort Opening is a chess opening named after Johannes Zukertort that begins with the move:

1. Nf3

Sometimes the name "Réti Opening" is used for the opening move 1.Nf3,[1] although most sources define the Réti more narrowly as the sequence 1.Nf3 d5 2.c4.[2]

A

1.d4.[3][4][5]

The move has been described by

Sicilian Defense. Other common transpositions are to various lines of the Queen's Gambit Declined (after e.g. 1.Nf3 d5 2.d4 Nf6 3.c4) or the Catalan Opening (after e.g. 1.Nf3 Nf6 2.g3 d5 3.Bg2 e6 4.0-0 Be7 5.c4).[6]

The main independent lines which usually start with 1.Nf3 are the Réti Opening (1.Nf3 d5 2.c4) and the King's Indian Attack (where White plays 1.Nf3, 2.g3, 3.Bg2, 4.e4, and 5.d3, though not always in that order). By playing 1.Nf3 White has prevented Black from playing 1...e5, and many players who want to play the English Opening but avoid the reversed Sicilian lines beginning with 1.c4 e5 opt to start the game with 1.Nf3 instead.[6]

In the

Encyclopedia of Chess Openings
, Zukertort Openings are classified in the coding series A04–A09. 1...d5 is under A06–A09, 1...Nf6 is under A05, and any other Black move is under A04.

Continuations

The Black responses which are given one or more chapters in the

Encyclopedia of Chess Openings are given below, ranked in order of popularity.[8]

1...Nf6

Like White's move, Black's move is non-committal as to opening. 2.d4 is identical to 1.d4 Nf6 2.Nf3 (see Queen's Pawn Game). 2.c4 is a common start for the English Opening or it may be brought back to the Queen's Gambit Declined 2.g3 is a common start for the King's Indian Attack.

1...d5

Black stakes a claim to the center. White has many transpositional options. 2.d4 is again the same as 1.d4 d5 2.Nf3 (see

Reti Opening or English Opening
.

1...c5

Black invites White to play 2.e4, transitioning into the

Sicilian Defense, or 2.c4, the Symmetrical Defense of the English Opening
.

1...g6

White can play 2.c4 for the

King's Indian Defense
.

1...e6

Like White's move, Black's move is non-committal as to opening. White can play 2.c4 for the

Indian Defenses, the King's Indian Attack, or the London System
, depending on Black's reply.

1...f5

After 1...f5, 2.d4 is the

Dutch Defense. 2.e4 borrows ideas from the Staunton Gambit
.
