Repertoire building is the process of choosing a small set of openings that suit your style and then learning their ideas, typical plans and key lines well enough to play them confidently. A [repertoire](https://georgelichess.com/glossary/opening-repertoire.md) is not a pile of memorized moves. It is a manageable collection of [openings](https://georgelichess.com/glossary/opening.md), one or two as White and a reply to each of the main first moves as Black, chosen because you understand the positions they lead to. Begin by looking at your own games. Which pawn structures do you handle well? Do you prefer open tactical fights or slow maneuvering? Pick openings whose typical middlegames match those answers.

Note where you left known theory and what you found over the board. Over a season, those notes turn into a repertoire that is really yours. Also called: building a repertoire.

Opponent preparation is the work of studying a known opponent's past games and habits before a round so you can choose openings and plans that steer the game toward positions where they are less comfortable. Also worth reading is [Thinking process](https://georgelichess.com/glossary/thinking-process.md). A thinking process is a consistent order of questions you follow on each move, from assessing the position and opponent's threats to choosing candidates and checking your choice, so decisions are less random.
