Réti Opening
The hypermodern masterpiece: White attacks the centre with pieces from a distance, leading to rich manoeuvring battles.
Réti Opening is one of the most compelling entries in the Encyclopaedia of Chess Openings — and a line that repays every hour you sink into it.
After 6…c5 the position resolves into a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated.

Main variations (12)

Advance System
A05The double-fianchetto Réti: mirror development with the first break deciding everything.
Cannstatter Variation

A16The Nimzo-Indian-style transposition — full central tension from move four.
Plans & pawn structures
- 1The centre is still fluid: decide early whether to lock it with a pawn advance or dissolve it with an exchange, because that choice picks the whole middlegame plan for you.
- 2Trade correctly: before every exchange ask which piece benefits from the resulting square colours and pawn structure.
Typical middlegame structures
The main line leads to a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated. No files have opened yet, so this is a manoeuvring struggle: improve your pieces and prepare the pawn break that will open the position on your terms.
Traps & tactical motifs
Every sharp opening has its traps — study the forcing lines around the centre and the f7/f2 squares before playing this in rated games.
Watch the typical motifs: pins against the pinned piece, knight forks after the natural captures, and queen sorties to a2/g2-style squares.
How to Play Against the Réti Opening
- As Black, strike at the fluid centre immediately with your own central pawn or piece pressure, before the opponent locks it into a shape that favours them.
Study plan & who it's for
Solidly intermediate. The main lines require real study, but the payoff is positions you can play for a lifetime. Best investment for White players around 1400–2000.
