1.Nf3 d5 2.b3 — Repertoire for White

Most White players who begin 1.Nf3 d5 reach for one of two well-trodden roads: 2.g3, the classical Réti, or 2.c4, transposing into English territory. This course is built on a third path. With 2.b3, White keeps all the flexibility of the Réti structure while stepping around the most heavily analysed theory — placing the dark-squared bishop on the long a1–h8 diagonal, pressing on Black’s centre, and supporting a wide range of plans that opponents are rarely prepared to meet.

That is the appeal GM Ioannis Papaioannou builds the whole repertoire around. The system is principled and ambitious, yet largely free of the forced lines that dominate mainline Réti practice. It is preparation that works in real games — and precisely because it sits off the main roads, it is preparation the opponent has usually never studied.

The character of the opening is one of long-range pressure rather than early confrontation. White develops harmoniously, keeps the central tension unresolved, and waits for Black to commit. A recurring theme runs through the course: White is happy to capture the light-squared bishop for a knight when the chance arises, then follow with a well-timed d2–d4 — but never rushes cxd5 unless Black has already played …c5 or …e5. Small rules of this kind, understood rather than memorised, are what turn a flexible setup into a genuine winning attempt.

The thread connecting every chapter is the same one that runs through all of Papaioannou’s work: when you understand the structures, the typical piece manoeuvres, and the practical judgment behind each plan, you no longer depend on memorisation. You play with clarity and confidence, and you keep the initiative even in positions the engine calls level. The focus throughout is on the setups that recur in practice, not the lines that appear once and vanish.

What you will master

• Setups with …Bf5 — the principled bishop development, and the fresh 4.Nh4 idea that treats it directly
• Setups with …Bg4 — both the main lines and the more advanced variations
• Setups with …e6 — long-term strategic play in solid, reversed-London and Torre-style structures
• Setups with …g6 — handling Black’s fianchetto
• Setups with …c5 — meeting Black’s most ambitious central challenge
• Rare lines and irregular tries — practical answers to the less-explored systems
• The typical pawn structures, the light-squared-bishop trade, and the d2–d4 timing that define the system
