About the 4.Bf4
4.Bf4 develops the bishop and pressures c7. Black strikes with ...c5 and ...Qa5, takes on c4 and wins the c5 pawn back after castling. The resulting positions are open and active for both sides.
Playing the Grünfeld Defence as Black? The 4.Bf4 (D82) begins 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Bf4 Bg7, and is one of 3 lines you can practise here. Go through the 4.Bf4 one move at a time, and when you know it, try to play the whole line without help. Knowing the moves is only half the work, so this page also covers the plans for the middlegame, the endgames to aim for and some grandmaster games. Add it to your set of defences against 1.e4 and 1.d4, and repeat it in speed mode or the drill until you no longer have to think about it.
