The Slav Defence: 1.d4 d5 2.c4... Bf5 arises after 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 5.a4 Bf5 and falls under ECO code D17. With the pawn on c4 blocking the Qb3 fork, Black can safely bring out the light-squared bishop. White now needs to recover the pawn, and two main methods are available. The Dutch Variation, 6. e3, is the classical main line: White plans to recapture with 7. Bxc4 and then continue with castling and preparation for the e4 advance. The Central Variation, 6. Ne5, takes a more aggressive approach by using the knight rather than the bishop to recover the pawn, leading to considerably sharper positions.
