Practice the Sicilian Defense in Najdorf, Dragon, Classical, and Alapin positions. Our Sicilian Defense guide is the source for 11 guided lines, 25 exercises, and six positions to play against the bot.
Eleven lines, one at a time: eight you play as Black, three as White. Finish a line and its checkmark stays in your browser.
Keyboard: ← → step through the moves. Click any move chip to jump.
Where the moves come from: every line and position in this trainer comes from our Sicilian Defense guide.
This is the core of the trainer. Twenty-five positions across six themes: book moves, plans, traps, punishments, structure, endgame echoes. Every line you step through is drilled at least twice, and the order is shuffled on each run so you answer from the board and not from memory of the queue. Click or drag a piece to play your answer. A wrong move gets a concrete refutation, and hints come in two stages before the answer itself is offered. Your score, streak, and solved drills stay in this browser.
Keyboard: Enter next drill · H hint · R reset the position.
Now play it out. Pick a variation, set the bot's strength (seven named levels, or the Elo slider from 600 to 3000), and start. The coach card watches your moves and speaks up when the game walks into something the guide covers. When the game ends, run the review.
Six positions from the guide, each with opposing goals tied to one board asset. Pick one to restart the board at that variation.
Four directions, each with a reason. Everything below links to a page that exists today.
