Short answer: To build a repertoire under 1400, pick one setup as White and one reply each to 1.e4 and 1.d4 as Black, then drill them until you can play them without help. The Opening Mastery Trainer (£27, $35) gives you ready-made lines to drill offline.
Most players below 1400 do not need a big repertoire. They need a small one they can actually remember on a tired Tuesday evening. This guide shows you how to choose it, how deep to go, and how to drill it, with a free method first and a paid option only where it genuinely helps.
What should a repertoire under 1400 actually contain?
It should contain three things: one opening as White, one defence against 1.e4, and one defence against 1.d4. That is the whole job. Anything beyond that is a bonus, and adding it too early is the commonest reason repertoires collapse.
You will also meet odd first moves, such as flank pawn pushes and early queen moves. You do not need a full opening for those. A short note on how you will develop and where your king goes is enough at this level. Our wider chess repertoire guide covers how many openings to carry as you grow.
How do you pick the openings?
Pick openings that lead to positions you enjoy playing, not the ones strong players use. Ask yourself three questions: do you like open, tactical games or slow, closed ones, do you prefer attacking or squeezing, and how much theory are you willing to hold in your head.
Then look for overlap. If your White opening and your Black defences all produce similar pawn structures, you learn the plans once and use them many times. That is a far better deal than seven unrelated systems. If you are not sure where to begin, the free chess openings quiz points you towards a style, and the opening training hub collects free pages for each opening.
How deep should you learn each opening?
Go only as deep as your opponents go, which at this level is usually not very far. Learn the first handful of moves, the main plan, and the answers to the three or four mistakes you see most often. A line you understand to move six beats a line you half remember to move fifteen.
Spend your effort on the traps and punishments, because that is where games are won below 1400. When an opponent leaves the main line, the real skill is knowing what you want in the position: where your pieces belong, which pawn break to aim for, and which squares to control. Memory carries you into the middlegame, and ideas carry you through it.
How do you drill a repertoire so it sticks?
Make yourself recall the moves instead of re-reading them. Reading a line feels like learning, but the test is finding the next move when nothing is on the screen to help you. Try this free routine:
- Choose one line and learn it in one sitting
- Three days later, play it from memory and note where you slip
- Fix only those slips, then test again two days after that
- After every game, check the first ten moves and drill any position where you left your preparation
Short and often beats long and rare. Ten minutes a day does more than one marathon on Sunday. The thinking behind this is in our guide to remembering chess openings without memorising.

Want the lines ready-made, with the drilling built in?
The Opening Mastery Trainer is one payment of £27 ($35), works offline, needs no account, and has a repertoire-builder quiz to help you choose.
What does the Opening Mastery Trainer do for this job?
It handles the parts of repertoire building that most people skip: finding lines, quizzing you, and bringing back what you forget. It combines book moves with popular moves from real Lichess games, so you practice against replies people actually play. Recall shows a position from your line and asks for the next move. Reconstruct asks you to play a whole line from move one.
A daily plan resurfaces lines until you know them, and the repertoire-builder quiz helps you choose a starting set. It is a single file you open in your browser, on desktop, phone, or tablet, with no account and no login. The live page also describes a guarantee, so read its exact wording before you buy.
Already own it? The optional CCS Hub has an online access plan for the trainers you own, so your repertoire and progress follow you from device to device with one sign-in. Staying subscribed long enough to match the one-time price unlocks the offline version too.
Who is this not for?
If you want to drill your own typed-in lines today, a build-your-own tool is the better match. The Opening Mastery Trainer is also a weaker fit if you need progress to sync between devices without the optional CCS Hub. In the offline file, progress is saved in your own browser on one device, and clearing browser data wipes it.
There is no chess engine, only the included lines, so it will not explain why a move is strong. It is a training tool and the page says plainly that it does not promise a rating gain. If you already have a detailed repertoire written out, a build-your-own tool may suit you better.
Are free tools and subscriptions enough?
Often, yes. Free explorers are excellent, and if you enjoy entering lines and scheduling your own reviews, you may never need to pay for anything. The cost is time and discipline, since nothing nudges you when a line is going stale.
Subscription platforms suit players who want depth and a big catalogue and will use it most weeks. They keep working only while you keep paying. A one-off trainer sits in between: less choice, no ongoing cost. For a side-by-side view, see chess opening trainer apps compared and our guide to the best chess opening trainers.
Questions people ask
How many openings do I need under 1400?
Three is enough to start: one setup as White, one defence against 1.e4, and one against 1.d4. Add a second option only when you have drilled these until recall feels easy and you keep meeting the same problem in games.
How deep should my opening preparation be?
Deep enough to handle the main line and the three or four mistakes you meet most. For most players below 1400, that means a handful of moves plus the plan. Understanding the typical pawn breaks and piece squares matters more than extra moves.
Is a paid opening trainer worth it at my level?
It can be if you forget lines and want a ready-made plan with reminders. If you enjoy building lines yourself in free tools, you may not need one. The test is whether you will really open it each day.
Can I add my own lines to the Opening Mastery Trainer?
Not at the moment. The trainer is built around its included openings, which number about 150 for White and Black, and custom lines are on our roadmap. If you need your own lines today, a build-your-own tool fits you better.
Does the Opening Mastery Trainer work offline?
Yes. It is a single file you open in your browser, and once downloaded it works without an internet connection on desktop, phone, or tablet. Progress is saved in that browser on that device, so the offline file does not sync. The optional CCS Hub does if you want that.
