The King’s Indian Defence is one of the most popular and historically rich openings in chess, known for its dynamic complexity and fierce battles for control. In this course, you will explore how to navigate White’s full pawn centre and understand the key plans for both sides. But understanding an opening doesn't stop at memorising theory. It's crucial to grasp the ideas and structures connected to the opening moves. Knowing how to apply these concepts and recognising mistakes from your opponent can give you a critical edge in the middlegame—a key component to transforming an opening advantage into a winning position.
