The Slav Defence: 1.d4 d5 2.c4... 3.Nf3 arises after 1.d4 d5 2.c4 c6 3.Nf3 and falls under ECO code D11. This is White's most popular continuation in the Slav, developing the knight while tightening control over e5. As with 3. Nc3, Black must steer clear of 3...Bf5, since 4. cxd5 cxd5 5. Qb3 essentially wins a pawn. Unlike after 3. Nc3, however, 3...dxc4 is also inadvisable here because White recovers the pawn comfortably with 4. e3 and 5. a4, as the knight on f3 is not exposed to a b5-b4 push. This leaves Black with two primary options. The overwhelming favorite is 3...Nf6, which usually transposes into a Semi-Slav after 4. Nc3, though independent lines such as 4. e3 (the Quiet Slav, where Nc3 is postponed or omitted entirely) also exist. The occasional 3...e6 generally leads back to 3...Nf6 positions. A third possibility is 3...a6, a solid but rare choice that typically reaches the main line of the Chebanenko Variation, although White can pursue a Catalan-style formation with 4. g3. With 12.6 million Lichess games across all rating levels, it is a well-established opening choice.
