Slav Defense - 4.Bf4 Lines (after 3.Nc3 3...Nf6)
White develops 4.Bf4, then tries 6.a4 to challenge your queenside after you play 5...b5. Castle, retreat your bishop to e7, then push b4 and bring your bishop to a6. Aim for a queenside pawn majority against White's isolated b2 pawn.
Let's learn the 4.Bf4 Lines! White develops the bishop to f4 and later offers a pawn trade on b5. We capture on c4, push b5, and bring our queen to b6. Let's begin with 1.d4.

Three Knights Variation (4.Nf3, after 3.Nc3 3...Nf6)
After 4.Nf3 dxc4 5.a4, meet 5...Bf5, 6.e3 e6 and develop with Bb4, O-O and Bg6, aiming for ...Qc7 to prep ...e5. You accept the bishop pair but get doubled g-pawns and a queenside majority.

4.Bg5 Lines (after 3.Nc3 3...Nf6)
White meets ...Nf6 with 4.Bg5, then often plays 6.a4, a mistake. Meet it with 6...b4, grab the pawn with 7...Nxe4, and push 8...b3. Trade on c3 with Nxc3, develop Be6, and hit White's weak pawns with Qa5.

Other 4th moves after 3.Nc3 3...Nf6 (4.e3)
After 4.e3, play 4...Bf5 and meet 5.Nf3 with 5...e6, offering a trade with 6...Bxd3 if given the chance. You aim for a solid, easy setup with your king safely castled.

Modern Line (3.Nf3)
White plays the Modern Line with 3.Nf3, then develops with 4.Nc3, eyeing your d5 pawn. You meet 1.d4 with ...d5 and 2.c4 with ...c6, so a pawn can recapture on d5 and hold the center. Aim for a solid Slav Defense structure with your center firmly supported.

Exchange Variation (3.cxd5)
White opens lines early with 3.cxd5, the Exchange Slav. You recapture cxd5, develop with Nf6, Nc6 and Bf5, then play e6 and trade bishops on d3 before castling. Watch the trap after 5.Bg5 Ne4 6.Nxe4 dxe4 7.e3 Qa5+, winning a piece. Aim for a plan with a6, Na5 and Rc8, trading rooks on the open c-file.
