Move by move
- 1.e4 – Bobby Fischer's signature opening move: 1.e4! You seize the center, open diagonal pathways for bishop and queen, and set up a dynamic game.
- 1...e6 – The French Defense with 1...e6: Black prepares the central d5 thrust while temporarily accepting passive scope for the light-squared bishop.
- 2.d3 – The cornerstone of the King's Indian Attack: 2.d3! You sidestep French theoretical mainlines and build the King's Indian reverse setup.
- 2...d5 – Black establishes a central presence with 2...d5, challenging your e4 pawn directly and opening a lane for the dark-squared bishop.
- 3.Nd2 – Flexible development with 3.Nd2: you reinforce e4 without obstructing the c3 push, preparing the kingside fianchetto in total harmony.
- 3...c5 – Black replies with 3...c5: immediately contesting White's central space and grabbing queenside territory before developing minor pieces.
- 4.Ngf3 – You develop the knight with 4.Ngf3 to control the d4 and e5 squares, retaining the total flexibility typical of the King's Indian Attack.
- 4...Nc6 – Black develops the knight to c6, intensifying pressure on d4 and e5 while adopting the classic setup against the King's Indian.
- 5.g3 – Preparing the kingside fianchetto with 5.g3: you clear the path for the bishop, which will soon command the long diagonal from g2.
- 5...Nf6 – Black develops the knight to f6, bolstering central presence and preparing to finish kingside development before seeking counterplay.
- 6.Bg2 – You place the bishop on g2: a powerful and clean diagonal post that effectively shuts down any enemy central breakthroughs.
- 6...Be7 – Black develops the bishop with 6...Be7: a restrained, flexible post that readies kingside castling without conceding attacking targets.
- 7.O-O – You complete kingside castling: your king is safe behind the pawn barrier, and the f1-rook is ready to slide to e1 for the attack.
- 7...O-O – Black also castles short to tuck their king away: pieces are fully deployed and the strategic battle for the center is about to ignite.
- 8.b3 – Setting up the double fianchetto with 8.b3! You prepare to develop the queen's bishop to b2 to strike along the great a1-h8 diagonal.
- 8...b6 – Black answers with 8...b6, aiming to develop their own light-squared bishop to b7 on the flank to neutralize your diagonal pressure.
- 9.Bb2 – You complete the double fianchetto with 9.Bb2! Both your bishops now criss-cross the board with tremendous long-range attacking power.
How to exploit the position
Deploy your forces in KIA harmony with d3, Nd2, g3, and Bg2
- Expand on the queenside with the flexible b3 push preparing Bb2
- Station the dark-squared bishop on b2 controlling the long a1-h8 light diagonal
- Maintain central tension without rushing to close the position prematurely with e5
- Capitalize on the crossfire of both fianchettoed bishops to dominate center and wings alike
Master tips
