What Réti Opening: Réti Accepted puts on the board
Black has a one-pawn material edge; white is to move.
No pawn occupies d4, e4, d5 or e5, so the central pawn structure is still fluid.
White can still castle either side; Black can still castle either side.
The c-file is half-open for White, giving that side a natural pressure lane.
What White is trying to build
Pressure the centre with pieces before deciding which pawns will occupy it.
Use a kingside fianchetto to make e5 and d4 central decisions costly.
How Black challenges it
Build a centre that can survive c4 and d4 pawn breaks.
Keep development flexible enough to meet a transposition.
The tactical pattern to recognise
The g2 bishop gains force when the centre or queenside opens.
Many move orders transpose into English, Catalan or queen’s-pawn structures.
What to check before committing
Allowing a large centre without preparing a pawn break against it.
Treating a transposition as if the original move-order plan still applies unchanged.
