The Réti Opening
The most polite first move in chess, and one of the most demanding. 1.Nf3 commits to nothing at all; 2.c4 attacks the centre without going near it. Everything the Réti does, it does from a distance.

The Réti Opening is 1.Nf3 and then 2.c4, and it is the least committal start in chess. The knight develops and blocks nothing; the c-pawn attacks d5 from the side. White will put bishops on b2 and g2 and control the whole middle of the board without ever standing in it.
That is the hypermodern claim in one picture: a big pawn centre is only an advantage while nothing is attacking it. The Réti lets Black build one and then takes it apart from a distance.
The main line: the double fianchetto
The Réti's main setup. Step through all eleven moves and count how many white pawns end up in the centre.
Now play White's side of it.
You are White. Build the Réti: knight, wing pawn, both fianchettos, castle - and do not put a pawn in the centre.
When Black grabs space with 2...d4
This is the real test. Black pushes past, and White answers by attacking the pawn chain from the side rather than in front of it.
The Réti Gambit line - Black takes space, White undermines it from the wing.
When Black takes the pawn
The Réti Accepted - taking is safe and it gives up the centre.
The trap: the knight that grabs c2
The one genuinely sharp moment in the Réti comes when Black meets 2.c4 with 2...Nf6 and then chases a pawn after the exchange on d5.
You are White. Trade, take the centre, and punish the greedy knight.
Black has played 2...Nf6. Exchange on d5, then take the centre with a pawn - and be ready for the knight that jumps to b4.
The plans, for both sides
White's plans. Build the shape - Nf3, c4, b3, Bb2, g3, Bg2, O-O - and then pick a target. If Black has pawns on d5 and e6, play cxd5 and pressure c6 down the c-file. If Black has built a big centre with ...d5 and ...e5, prepare d3 and e4 and blow it up from underneath. If Black plays ...d4, undermine with b4 and a3. The rule that holds all three together: you never block the centre, you dissolve it.
Black's plans. The three replies above are all sound, and the choice is about temperament. ...c6 and ...Bf5 is the solid one and gives White the least to work with. ...dxc4 is the simplest - hand the pawn back and take space. ...d4 is the ambitious one and it is exactly the position White is hoping for, so play it knowing what is coming.
The tactics come from the two long diagonals. A pin against a queen on the a1-h8 diagonal is the Réti's signature, a fork on a knight that has wandered to b4 or e4 is what the trap above is made of, and castling early is easy here because nothing in your own position is loose.
If the same ideas with a committed c-pawn appeal more, that is the English Opening. If you want the fianchetto with a big centre behind it, that is the Catalan.
Try it
You opened 1.Nf3 and Black played 1...d5. Play the move that makes this a Réti.
The Réti is the opening to learn when you want to stop memorising and start understanding. It gives you almost nothing to remember and almost everything to think about - and thinking about the board is exactly what the lessons are for.
Common questions
- What is the Réti Opening?
- 1.Nf3 followed by 2.c4, usually with b3, Bb2 and g3, Bg2 to follow. White develops without putting a single pawn in the centre and attacks Black's centre from the wings instead - the purest expression of the hypermodern idea that the middle of the board can be controlled rather than occupied.
- Is the Réti good for beginners?
- It is safe and it is hard. Nothing goes wrong in the first ten moves, but the positions that result have no obvious plan unless you understand what the two fianchettoed bishops are doing - and a beginner given a position with no pawn breaks tends to shuffle. Learn a classical opening first, then come back once 'control the centre' means more than 'put a pawn there'.
- What is the main line of the Réti?
- 1.Nf3 d5 2.c4 c6 3.b3 Nf6 4.g3 Bf5 5.Bg2 e6 6.O-O, the double-fianchetto setup. White has bishops on b2 and g2 pointing at both long diagonals, a knight on f3, and not one pawn past the third rank. The plans are d3 and e4 later, or a queenside squeeze with Rc1 and cxd5.
- What is the Réti Gambit?
- 1.Nf3 d5 2.c4 dxc4, taking the pawn. It is not really a gambit: after 3.Na3 or 3.e3 White wins the pawn straight back, and Black has given up the centre for it. The genuinely testing reply is 2...d4, grabbing space, when 3.b4! offers a wing pawn to undermine the big centre from the side.
- Can the Réti transpose into other openings?
- It transposes more than any other opening. Depending on what both sides play, 1.Nf3 can become an English, a Catalan, a Queen's Gambit, a King's Indian or a Nimzo-Indian. That flexibility is the point - and the cost is that you need to know something about the destination, not just the road.
- Who was Réti and why does the opening matter?
- Richard Réti was one of the founders of the hypermodern school in the 1920s, and he used this move order to beat Capablanca in 1924 - ending an eight-year unbeaten run. The point he was proving is now ordinary chess knowledge: a pawn centre you can attack is a target, not an advantage.
