Practice Chess Openings, One Move at a Time
Knowing an opening is not the same as having read about it. The line is only yours when your hand finds the moves in order, against the board, without a book open beside you. That is what this trainer drills: pick any of the 60+ mainlines here, choose a colour, and play your side of the theory move by move. The trainer answers instantly with the book reply, a wrong move is taken straight back so you can try again, and the line counts as mastered only when you play it clean — no mistakes, no hints.
Every line on this page is a genuine mainline, seven to eleven moves deep for each side — deep enough to carry you through the opening into a middlegame you understand, and short enough to actually remember. Each one has been replayed and verified move by move before publication.
How to Drill a Line
Play the line once with the Watch button to see where the pieces belong, then play it yourself until it comes out clean. Switch colours and play the same line from the other side — nothing teaches you an opening's ideas faster than having to find the replies you usually face. Come back tomorrow and run your mastered lines again; opening memory fades quickest in the first few days.
Moves Are Not Enough
Every line here comes with a note on what the opening is actually trying to do — the pawn break it plays for, the piece that carries the plan, the imbalance it accepts. Read it before you drill. A move order backed by an idea survives the first surprise your opponent throws at you; a memorised one does not.
The Opening Families Covered
- Open games The Italian, Ruy Lopez, Scotch, King's Gambit and their cousins — the classical battleground after 1.e4 e5, where development and the centre are everything.
- The Sicilian The Najdorf, Dragon, Sveshnikov and the main anti-Sicilians. The sharpest reply to 1.e4 and the most analysed opening in chess.
- French & Caro-Kann The solid counter-punching defences, plus the Scandinavian, Pirc, Modern and Alekhine for players who like to fight on their own ground.
- Queen's pawn The Queen's Gambit in its declined, accepted and Slav forms, the London System, the Catalan and the Trompowsky.
- Indian defences The Nimzo-Indian, King's Indian, Grünfeld, Benoni and Benko — Black's dynamic answers to 1.d4.
- Flank openings The English, Réti, King's Indian Attack and Bird's — controlling the centre from the wings.
How Should I Practice Chess Openings?
Little and often beats long and rare. Two or three lines a day, played until they come out clean, will build a full repertoire in a month. Drill the openings you actually reach in your own games first — if you open 1.e4, master the Italian before you touch the Catalan. And when a line is comfortable from one side, flip the board: playing the other colour's moves shows you exactly what your opponents are trying to achieve against you.
When a line is in your hands, take it to a real game: play it against Stockfish, test yourself with the chess rating test, sharpen the tactics that follow with checkmate puzzles, or see how the world's best handled the same opening in the grandmaster games library. When a game of your own goes wrong out of the opening, the game analyzer will show you an engine's view of every move.
How Are Mastered Openings Tracked?
Every opening line you complete without mistakes or hints counts as mastered. Your mastered openings are stored in your own browser, so you can drill chess openings online as often as you like.
Which Opening Should a Beginner Learn First?
Start with the Italian Game as White: every move develops a piece, fights for the centre or protects the king, so it teaches opening principles while it scores points. As Black, the Philidor or Scandinavian against 1.e4 and the Queen's Gambit Declined against 1.d4 are hard to get wrong. The trainer marks each line Beginner, Intermediate or Advanced, so the select list doubles as a study order.
How Many Moves of Theory Do I Need to Know?
Fewer than you think. Below master level, games leave known theory within eight or nine moves, so a line you can play confidently to move ten is a genuine edge. What matters is knowing the ideas when the book runs out — which pawn break your position wants, where each piece belongs, which side of the board your play is on. That is why every line here stops while the position is still a plan rather than a puzzle.
