Step 1
Guided
The starting square lights up, an arrow shows the move. You grab the piece and place it. You can't go wrong — you learn the motion.
The method
You play, it sticks, you win.
Three passes with fading guidance. By the end, you play the opening from memory in real games — while your opponent is thinking, you already know what to do.
4.Ng5
The knight heads to g5: the source square lights up and the path appears. All you do is play the move yourself.
Step 2
Hint
Less help this time. Just a hint if you get stuck. You replay the line leaning on your fresh memory.
Step 3
Memory
No more guidance. You replay the whole line from memory. When you finish it, you know it by heart — ready to use in rated games.
And every move has its why
"1.e4 — You take the center and open lines for the bishop and queen." You don't memorize moves in a vacuum: you understand the plan, so you know what to do even when your opponent leaves theory.
Why Prologue
Built to remember, not to review endlessly.
It sticks in real games
No video to watch passively: you replay every move yourself. That's what makes the line come back when you need it, mid-game.
You play well from move 1
Every line comes from verified sources and is engine-checked. The moves you memorize are the ones that give you a good position.
Zero wasted time
Each opening is tagged by its real popularity across 8.2M games. You study only what your opponents actually play — every minute of practice pays off in games.
A plan, not a recitation
A clear sentence explains the idea behind every move. When your opponent deviates, you know what to do instead of panicking.
