Overview

Queen's Gambit Declined: Semi-Tarrasch Defense, Krause Variation belongs to the gambit family of chess openings (ECO D50, Closed & Semi-Closed Games). It trades material for attacking chances — a classic trade-off that has fascinated players from the Romantic era to modern correspondence chess.

It begins with 15 plies and takes 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 c5 5. Nf3 cxd4 6. Nxd4 e5 7. Ndb5 a6 8. Qa4 to reach the canonical position.
