Own the first five moves.
A daily study card drawn from 20 classic mainlines across the king's-pawn, queen's-pawn, and flank families — Ruy López to the Catalan. Each card shows the opening's name, its ECO code, the move line in standard notation, and a live mini board rebuilt to the exact position after five plies, with the last move highlighted.
The daily pick is deterministic, so every visitor studies the same opening all day; tap ↻ to shuffle a random one anytime. Names and descriptions ship in all 21 languages, with full RTL support for Arabic and Hebrew, and the whole card — board included — recolors from a single ?accent= parameter.
