1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 c5
The Semi-Tarrasch keeps Tarrasch-style activity while using ...Nf6 first, often avoiding a pure isolated pawn and aiming for a more balanced structure.

Strategic Ideas
- Refined ...c5 break: Black combines activity with better coordination.
- Flexible recapture: ...Nxd5 often avoids a long-term isolated pawn.
- Piece pressure: Open lines favor active minor pieces and central control.
- White's plan: White seeks stable space and central pressure.
- Theory-sensitive: Move-order details strongly affect evaluations.
Main Continuations
Mainline
5.cxd5 Nxd5 6.e3 Nc6 7.Bd3

Exchange Route
5.e3 Nc6 6.Bd3 dxc4

5.Bg5 Be7 6.e3
White develops smoothly and avoids early tactical volatility.
Typical Plans
For White
- Build control: Consolidate central squares and avoid tactical slips.
- Press d5: Use rooks and minor pieces to question Black's center.
- Choose structure: Decide early between simplification and tension.
For Black
- Stay active: Development speed is critical in open structures.
- Coordinate breaks: ...e5 and ...cxd4 are key timing decisions.
- Equalize dynamically: Piece activity can offset small spatial deficits.
Common Mistakes
White: Automatic exchanges can release Black's position too easily.
Black: Passive piece placement undermines the whole concept of the line.
