Hi! I'm a tool to teach you the most popular chess openings and their variations.
Pick openings in the Opening Chooser, then play the main line for your colour, and I will play many variations against it.
I use Spaced Repetition to teach you as quickly as possible, where I often show you lines you find difficult, and rarely show you the easy lines.
A line only counts as learnt when you play it without mistakes or hints.
Hover over an opening to see its position and how many of its lines you have learnt and are due.
Keys: N next line, F flip colour, U undo, H hint.
