Plans to Know

Black: ...d6 and ...e5

...d6, ...Nc6, ...e5

The most thematic central challenge. Black wants active pieces and a clear plan against White's center.

Black: ...c5 Break

...c5 vs d4

Undermining d4 often opens lines for the queen and the g7 bishop.

White: e4 Expansion

c4, Nc3, e4

White often prepares e4 carefully, aiming to build a big center without overextending.

Know the Main Setup

Understanding the typical pawn breaks is more important than memorizing long move orders.
