Overview

Semi-Slav Defense: Main Line is a specific line in the Closed & Semi-Closed Games family (ECO D46), arising from a recognised theoretical position.

The Closed & Semi-Closed Games group covers closed and semi-closed games — 1.d4 systems characterised by long strategic manoeuvring rather than early tactics.

It begins with 19 plies and takes 1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. e3 e6 5. Nf3 Nbd7 6. Qc2 b6 7. b3 Bb7 8. Bd3 Be7 9. O-O O-O 10. Bb2 to reach the canonical position.

The line refines Semi-Slav Defense: Chigorin Defense, which traces back to the root opening Queen's Pawn Game.
