Slav Defense - 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.

Let's learn the 4.Bg5 Lines! White develops the bishop to g5 and pushes e4 to attack our pawn on c4. We defend with b5, then punish White's mistake with b4 to win material. Let's begin with 1.d4.
