• Andy Woodward: The Bulletproof 1.b3 Repertoire

  In the ChessBase training course "The Bulletproof 1.b3 Repertoire", GM Andy Woodward explains how White can meet King’s Indian setups after 1.b3. He presents two practical systems: a sharper setup with e3, Be2 and d4, where White challenges Black’s central play, and a quieter positional approach with c4 and a double fianchetto. The lesson shows the course’s main idea well: giving players a simple, practical and venomous repertoire that avoids heavy theory while still creating uncomfortable problems for Black.
