Against the King's Indian setup is variation 2 of 6 in the London System course, a beginner opening course for White (ECO A48). It runs 15 moves and begins 1. d4 Nf6 2. Nf3 g6 3. Bf4 Bg7 4. e3 O-O …. Black fianchettoes with ...g6 and ...Bg7. White keeps the same structure and often plays h3 so the bishop on f4 has a retreat square. In the lesson every move is explained on a board and then drilled; it is free.
Move by move
1. d4 – Takes the centre and opens a path for the dark-squared bishop.
1... Nf6 – Black stops e4 and keeps options open.
2. Nf3 – Develops and controls e5.
2... g6 – Black plans to fianchetto the bishop on g7, where it presses on d4 and the long diagonal.
3. Bf4 – The London bishop, outside the pawn chain before e3.
3... Bg7 – Completes the fianchetto.
4. e3 – Supports d4 and frees the light-squared bishop.
4... O-O – Black castles early, which is typical of this setup.
5. Be2 – Against the fianchetto the bishop is better on e2: d3 would run into ...Nh5 or ...d6-e5 ideas with tempo.
5... d6 – Black prepares the central break ...e5.
6. h3 – Gives the f4 bishop a safe square on h2 and stops ...Nh5 or ...Bg4 ideas.
6... Nbd7 – Supports the ...e5 push.
7. O-O – White castles and both sides have finished developing.
7... c5 – Black hits d4 from the side, the second typical break next to ...e5.
8. c3 – Back to the London pyramid: d4 is now supported by both pawns, and ...cxd4 is met by exd4 or cxd4.
