Réti Opening: Advance System
The double-fianchetto Réti: mirror development with the first break deciding everything.
Réti Opening: Advance System belongs in every serious player's toolbox: a system with real teeth, clear ideas and a pedigree stretching back decades.
After 5…d6 the position resolves into an open centre — the central pawns have largely been traded, so open files and piece activity decide the game rather than pawn play.
The Advance System is one of the defining branches of the Réti Opening — the line you reach when both players want the full fight rather than a quiet draw.

Plans & pawn structures
- 1In this open centre, development speed and king safety trump material — get castled, connect the rooks onto the open lines, and look for tactics against the less-coordinated side.
- 2Watch the pawn breaks — both yours and your opponent's. In these structures the player who times the central break better usually wins the game.
- 3Trade correctly: before every exchange ask which piece benefits from the resulting square colours and pawn structure.
Typical middlegame structures
The main line leads to an open centre — the central pawns have largely been traded, so open files and piece activity decide the game rather than pawn play. 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 Advance System
- In this open position Black must match development tempo for tempo — fall behind on castling and coordination and the open lines turn against you at once.
Masters & history
Réti used his opening to beat Capablanca in the legendary 1924 New York tournament, announcing the hypermodern era.
