The idea
Black exchanges the e5 pawn for White's d4 pawn, leaving an asymmetrical centre: White has space on e4 while Black develops behind d6.

What White wants
- Use the extra central space and the f4–f5 expansion
- Develop with Be2 or Be3 and Re1 and press on the kingside
- Keep useful attacking pieces while watching Black's central counterplay
What Black wants
- Copy White's development and trade pieces
- Play ...d5 at the right moment to free the game
- Aim for a comfortable, balanced middlegame
Key idea
Understand this and the moves stop needing to be memorised.
Space against a compact centre
The structure is not symmetrical: White's e-pawn remains on e4 and Black's d-pawn remains on d6. White can expand with f4, while Black challenges the centre with ...d5 when it is ready. Development and the timing of that break determine whether White's space becomes an attack.
Common mistake
Pushing f4 and f5 without checking ...d5 or pressure on e4. The kingside expansion gains space but costs time, and a central break can expose White's pieces before the attack is ready. Coordinate the rooks and minor pieces first.
