About OpeningCraft

Why OpeningCraft exists

OpeningCraft is made by Josep Serrano Ballestero. It started with a simple problem: no website or app trained openings the way Josep wanted. Some were paid and only let you do two lines, and others didn't have the right openings.

OpeningCraft is the answer: a trainer focused on the few lines that matter, chosen for each player’s level, instead of an endless tree of variations where you get lost.

Where the lines come from

The lines come from real games in the Lichess database, split by rating band: you learn what opponents at your level actually play, not just master-level theory.

Every line is checked with a chess engine, and every move is verified to be legal. Within each opening, the traps and opponent mistakes that are most common at your level come first, followed by the theory.

How you learn

Lines come in blocks of 5: first we show you each move with an arrow and explain why it is played; then your opponent moves and you have to find the reply. Lines you have learned come back for review before you forget them.
