Reti Opening
1.Nf3
A repertoire for White · ECO A04–A09
The Reti Opening (1.Nf3) is the ultimate flexible start: develop first, strike at the center when it suits you. Named for the hypermodern pioneer who used it to beat Capablanca, it lets you steer every game toward structures you know better than your opponent.

Key ideas
- Develop with 1.Nf3 and g3 before committing a single central pawn — information first, structure second.
- Pressure d5 from the flanks with c4 and the Bg2 — the hypermodern recipe in its purest form.
- Choose your transpositions: Catalan-style, English-style, or pure Reti — always on your terms.
- Play the double fianchetto with b3: two raking bishops and a middlegame plan that repeats forever.
Typical plans and structures
Against ...d5 setups White plays c4 and b3, exchanging or undermining the center and working the long diagonals; the thematic Ne5 with f4 or the d4 break arrives once Black's setup is fixed. Against King's Indian-style defenses, White claims the center after all with d4 at the right moment — a tempo up on known theory. The course teaches the Reti as a system of decisions: which structure to steer toward against each Black setup, and the plans that follow.
Who should play it
Positional players who value flexibility and move-order mastery over forcing theory — and want one opening that quietly controls what kind of game gets played.
Frequently asked questions
Is the Reti a real attempt for an advantage, or just avoiding theory?
Both: it avoids your opponent's preparation AND poses genuine problems — the pressure against d5 with c4 and Bg2 is a real strategic question, and world champions from Kramnik to Carlsen have used the Reti to win serious games.
What is the hypermodern idea behind 1.Nf3?
Instead of occupying the center immediately, White controls it from a distance — knight, fianchettoed bishop, the c4 lever — and occupies it later, when doing so comes with tempo. Richard Reti proved the concept by beating Capablanca with it in 1924.
How do I choose between the Reti and the English?
They are cousins and often transpose (1.Nf3 with c4 reaches many English positions). The Reti move order dodges 1.c4 e5 — the reversed-Sicilian lines — which many players prefer to avoid; this course leans on that practical advantage.
