Learn

Get better between club nights.

Plain-words guides to club chess, an opening trainer for the lines you’ll actually meet, and puzzles from real games. One Learn level keeps track of the studying, and nobody sees it but you.

Your Learn level

Only you see it.

Guides

Club chess, explained: walking in for the first time, the clock, the handshake, keeping score, and what that number next to your name means.

All 8 guides, organizers’ too

Opening trainer

40 openings, a few lines a day, and each line comes back just before you’d forget it. Learn it on the bus, play it on Board 4.

Pick an opening for White or Black and learn its lines one move at a time on the board. Reps in the two days before your club night count as prep, and your book stays in this browser.

How it works

  1. Learn a line: the moves, and the plan that goes with them.
  2. Play it back from memory. A slip just means it comes back sooner.
  3. Each clean run adds a mark. The fifth books the line: it’s yours.

Puzzles

Free puzzles from real games, picked at about your level: a little harder as you solve, a little easier when one gets away.

Solve one clean and it’s worth XP, more for the tough ones; take a hint and it’s worth half. No clock and no account needed. Or work through a collection, easiest first:

Find the move
White to play. Take as long as you’d take on Board 4.
