Petrus method

The Petrus method is a popular chess opening strategy designed to help players develop their pieces efficiently and control key areas of the board. It emphasizes rapid development of the knight and bishop early on, followed by early castling to safeguard the king. The goal is to create a solid, flexible position that allows for smooth piece coordination and prepares for effective middle-game play. Named after the Dutch grandmaster Johan Petrus, this approach is especially useful for club players seeking principled development and a structured plan during the opening phase.
