Chess Structures: A Grandmaster Guide, Chess Structures: A Grandmaster Guide
This is the definitive modern masterpiece on middlegame strategy. Flores Ríos breaks the game down into 28 pawn structures. He bypasses the fluff to teach you the exact plans, piece placements, and risks associated with each skeleton. The model games are brilliantly selected to isolate the structural themes without getting bogged down in messy tactical anomalies. It is an absolute must-read that completely reshapes how you look at the board. Personally, I learnt through the chessable course, where it is narrated by Peter Heine-Nielsen.
