The Slav Defence: 1.d4 d5 2.c4... 6.e3 arises after 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 5.a4 Bf5 6.e3 and falls under ECO code D18. With 6.e3, White clears a path for the light-squared bishop so it can recapture the pawn on c4. A trade-off of this approach is that the dark-squared bishop remains temporarily hemmed in, with White planning to free it later through the e4 advance. The response 6...e6 is nearly universal, as Black aims to develop the dark-squared bishop to b4, a square left vulnerable by White's earlier 5.a4 (which was played to prevent ...b5).
