Four Pawns Attack is variation 4 of 6 in the King's Indian Defence course, a advanced opening course for Black (ECO E77). It runs 24 moves and begins 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 …. White builds the biggest centre possible with f4. Black must hit it at once with ...c5 and ...e6, open the e-file and use the long diagonal before White's pawns roll forward. In the lesson every move is explained on a board and then drilled; it is free.
