The Slav Defence: 1.d4 d5 2.c4... Bf5 arises after 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.e3 Bf5 and falls under ECO code D12. Black seizes the chance to activate the light-squared bishop outside the pawn chain. The knight on f6 neutralizes the usual Qb3 trick, since after 5. cxd5 cxd5 6. Qb3 Qc7, the fork on b7 and d5 is no longer effective. White's most ambitious answer is 5. Nc3, which develops actively while intensifying pressure against d5. The main alternatives are 5. cxd5, entering the Exchange Variation where White's dark-squared bishop ends up hemmed in behind its own pawns, and 5. Bd3, which leads to a trade of light-squared bishops. With 1.1 million Lichess games across all rating levels, it is a specialized opening choice.
