Built around you

Openings that fit your style of play

Tell us how you like to play and your rating — Opening Guru points you at the lines that actually suit you, not a generic one-size-fits-all repertoire.

Aggressive

Sharp attacking chess and gambits that fight for the initiative from move one — think the King's Gambit or the Najdorf Sicilian.

Positional

Slow strategic squeezes where small advantages pile up — the Ruy Lopez, the Catalan, patient maneuvering games.

Tactical

Open positions full of combinations and calculation — the Italian, the Scotch, and lines that keep the board on fire.

Solid

Safe, low-risk structures that are hard to break down — the Caro-Kann, the London System, rock-solid setups.

Universal

A flexible, balanced repertoire that adapts to any opponent — a little of everything, ready for whatever comes.

Beginner-friendly

Simple, principled openings with clear plans and few traps to memorize — the perfect place to start and grow.

Powered by real games

Know what actually works — not just theory

Every position is backed by the outcomes of millions of real games, so you can pick lines that score, not just lines that look good on paper.
