How it works

RBOT builds opening repertoires from real games — the moves your opponents at your rating level actually play, answered with engine-optimal responses and commented for your level.

Rating-based opening trees
The opponent plays the moves most common at your rating level — not what a computer considers theoretically optimal. You can train directly from the tree, drilling the lines until the responses become automatic.
Guide — Strategy, Gameplan & Training
Every opening includes three layers of instruction: a strategic overview, a move-by-move gameplan, and a training guide with tactical motifs and practice methods adapted to your rating tier.
Piece Maps
Where does the knight actually end up in this opening? Where does the rook belong? Piece Maps answer those questions visually — each piece gets a heatmap showing its activity across 200 games at your level, a combined view of its most important squares, and the pawn structure that typically arises. It turns abstract opening knowledge into a concrete picture.
Upgrade Paths
When you advance a tier, a clear breakdown of exactly what changes — new lines, new dangers, deeper positions.

The method

  1. 1
    Pick an opening and a tier. Each tier corresponds to a rating range — 1400, 1600, 1800, or 2000. The tree at each level is built from games actually played in that range.
  2. 2
    Study the tree. Browse the moves your opponents will play and learn the recommended response. Every node includes a comment explaining the idea behind the move.
  3. 3
    Train until it sticks. Use the built-in trainer to drill the lines. The tree feeds the positions — you supply the moves.
  4. 4
    Check the Guide. Each opening has a strategy tab with an overview, a move-by-move gameplan, and a training section with the typical tactical themes and weaknesses to exploit.
  5. 5
    Explore the Piece Maps. See where each piece typically ends up — and where it belongs. Heat maps, peak boards, and pawn structure visualised across hundreds of games.
  6. 6
    Upgrade when you're ready. Moving up a tier adds the lines your stronger opponents play. The Upgrade Paths section shows exactly what changes between tiers.
