Practise the King's Indian Defense: Orthodox Variation

The Orthodox Variation of the King's Indian Defense (1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2) is White's natural development with a big pawn centre. Play White's moves of the line from memory — 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 — and the trainer plays Black's replies; "Play the other side" turns it around.
