Build Your Chess Opening Repertoire
Train the openings you actually play until the moves become automatic. The repertoire trainer drills your chosen lines move by move and tells you the moment you deviate, so mistakes get corrected before they become habits.

Why train a repertoire
Knowing an opening and being able to play it under time pressure are different skills. Repetition closes that gap.
- You stop burning clock time on moves you should already know.
- You reach familiar middlegames where you understand the plans.
- You spot immediately when an opponent leaves theory — and can punish it.
How to build one
A working repertoire is smaller than most players expect.
- Pick one opening as White and one defence against each of 1.e4 and 1.d4.
- Learn the first five or six moves plus the typical plans, not deep theory.
- Add new lines only when you actually meet them in your games.
- Review your games in that opening to find where your knowledge runs out.
Frequently asked questions
How big should a chess opening repertoire be?
Smaller than most players think. One opening as White and one defence against each of 1.e4 and 1.d4 is enough well past club level. Depth in a few lines beats shallow knowledge of many.
How do I memorise chess openings?
Do not memorise them in isolation — drill the moves with spaced repetition and learn the plan behind each one. Understanding why a move is played is what survives when your opponent deviates, which happens in most games.
