The Queen's Pawn – Krause Variation arises after 1.d4 d5 2.Nf3 c5. ECO code: D02.

Black immediately challenges d4 with ...c5, similar to the Tarrasch Defence. After 3.dxc5, 3.c4, or 3.e3, the position takes different strategic directions. The early ...c5 is fully sound and leads to active play for Black.
