The Reti Opening arises after 1.Nf3 d5 2.c4 and falls under ECO code A09. A quintessential hypermodern opening, the Reti uses minor pieces rather than pawns to contest the center. Black has several ways to respond: moves like 2...c6 or 2...e6 typically lead to transpositions into the Queen's Gambit Declined or Slav Defense, though White can diverge with 3. g3, reaching positions resembling or directly transposing into the Catalan Opening (normally arrived at via 1. d4 Nf6 2. c4 e6 3. g3), or even 3. b3!?. If Black captures on c4 or pushes ...dxc4 and ...d4, the advanced d4 pawn can be annoying for White as it controls c3 and e3, squares where the knight and bishop would naturally develop. White then undermines this pawn with moves like e3, a3 followed by b4, while Black tries to maintain it with ...Nc6 and ...c5. The sharpest continuation is the Reversed Blumenfeld Gambit: 3. e3 c5 4. b4 dxe3 5. fxe3 cxb4 6. d4, where Black holds an extra pawn on b4 but it is weak, and White's central control and development provide adequate compensation, yielding roughly a 52% score in practice. With 7.1 million Lichess games across all rating levels, it is a well-established opening choice.
- Control the center from a distance instead of occupying it: hold back the d- and e-pawns and fianchetto at least one bishop.
- Hit Black's d5 pawn from the side with c4.
- Expand on the queenside, often by playing b4.
History and Notable Players
The earliest known analysis of this opening dates back to Réti–Rubinstein, Karlovy Vary, 1923. The opening is named after Richard Réti. It arises from the Zukertort Opening: d5. Among the most prolific practitioners on the White side are Peter Szekely (90 games), Aleksander Wojtkiewicz (56 games), Lutz Espig (54 games). On the Black side, notable exponents include Igor Khenkin (29 games), Aleksey Dreev (29 games), Michele Godena (28 games).
Réti introduced the system to master play in early 1923, and Hans Kmoch coined the name after Réti's game against Rubinstein at Karlovy Vary that year. Its most famous moment came at New York 1924, where Réti used it to beat reigning world champion Capablanca. A century later, Gukesh won game 11 of the 2024 World Championship with it.
Named after: Richard Réti (1889-1929), the Czechoslovak master and leading hypermodern who brought the system into top-level play.
Notable players: Richard Réti, Alexander Alekhine, Gukesh Dommaraju
Réti used this opening to beat reigning world champion Capablanca at New York 1924, and Tartakower quipped that this 'opening of the past' had become, around 1923, the opening of the future.
