Learn, then practice, then time trial: how to actually drill an opening
Reading a line once does not make it yours. Here is the order of work the trainer is built around, and why the last step is the one that scores points.
Most players study an opening the same way: watch a video, click through a PGN once, feel like they know it. Then in a real game they reach move six, the opponent plays something slightly different, and the knowledge evaporates.
The problem is not the material. It is the order of work. Recognising a move when you see it and producing it when nobody tells you it is coming are two different skills, and only the second one wins games. Our trainer is built around four steps, and they exist in that order on purpose.
1. Browse — get the shape of the position
Browse mode just puts the line on the board so you can look at it. No quiz, no timer. This is the step people skip, and it is the one that gives you something to hang details on later.
You are not memorising here. You are noticing: which pawn is committed, where the pieces want to go, which side the play is on. When you open the library, every course card shows you how many lines it contains, so you can pick something you can realistically finish rather than a monster.
2. Learn — one move at a time, with the idea attached
Learn mode walks the line and explains each move where the explanation matters. Not a wall of notation — a comment on the moves that carry the idea, in plain language.
This is the difference between "I have seen this position" and "I know why this move is played here". If you are going to spend time on one step, spend it here. The comments are the part you will actually remember at the board, because they give the move a reason.
3. Practice — play the line with nothing in front of you
Practice mode takes the training wheels off. The board asks for the next move and you have to produce it. Get it wrong and you find out immediately, while the position is still in front of you.
Two things make this awkward at first, and both are the point:
- You drill as White or as Black separately. Knowing your own side is half the job. The half you skip is the half that beats you.
- It feels slower than reading. It is. You are building recall, and recall is slower to build and far slower to lose.
Come back the next day rather than grinding for an hour. Spaced repetition beats volume, which is why we track mastered lines per course instead of just minutes trained.
4. Time trial — the step that finds the real gap
Time trial is Practice with a clock, and it is where the honest information shows up. A line you can produce slowly is a line you do not have yet. Under time pressure you find out which moves you actually know and which ones you were reconstructing from context each time.
It is available after you sign in, because it is the step that only makes sense once you have progress worth measuring against.
What to do with the information afterwards
Every completed line feeds the progress bar on the course card, so you can see which courses are half-learned instead of guessing. Your practice days build a streak, and points across sessions put you on the leaderboard — mild pressure, mostly useful as a reason to come back tomorrow.
Openings are only part of it. The endgame vault drills the same way, learning the idea first and then making you convert it without help. Puzzles run on the same principle with tactics, over 99,000 positions across nine rating brackets, matched to your solving rating.
Start with the free one
You do not need an account to try this. The Fried Liver Attack is open to everyone: browse it, learn it, then play it back without help. It is short enough to finish in one sitting, and if the loop works for you, you will know quickly.
