Everything on this page comes out of our Ruy Lopez guide. Learn the 13 commented lines, drill the 29 decisions until they come without thinking, and play the bot last. Playing first is how most people waste an opening they have not learned yet.
Thirteen lines, one at a time: seven you play as White, six as Black. Step through the moves and the comment for each half-move appears as you reach it. Finish a line and its checkmark stays in your browser.
Keyboard: ← → step through the moves. Click any move chip to jump.
Where this comes from: every line, comment, and engine number in Learn and Drill is lifted from our Ruy Lopez guide. That includes the evaluations you will see quoted: +0.33 for 9.h3 in the Closed tabiya, about -3.15 for White once the Noah's Ark net closes, +1.28 for 7.Re1 in the Open.
This is the core of the trainer. Twenty-nine positions across six themes: book moves, plans, traps, punishments, structure, endgame echoes. Every one of the 13 lines you just stepped 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 2500), 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 variations from the guide, each with a goal to hit. Picking one restarts the board at that variation's position.
Four directions, each with a reason. Everything below links to a page that exists today.
