Every part of your chess, in one place.
Openings, traps, board vision, tactics out of your own games and mates on tiny boards. All of it free, and none of it a grind.
The openings work by their forks. Replaying all 100 lines of the Caro-Kann repertoire from move one is 753 of your moves, and only 389 of them are different. Across the whole library, replaying every line from move one is 37,208 of your moves, and, counted course by course, only 16,560 of them are different.

Whatever you want to get better at is already here
Six ways to work, nothing to install. Pick the part of your game that is letting you down and start there.
Openings
For both colours, drilled by their branch points rather than move by move. Anyone can add their own.
25+ trapsTraps
Ones people genuinely fall into, each with what it wins and the moves that spring it.
4 drillsBoard vision
Coordinates, blindfold games against the engine, position recall, and calculation with the board hidden.
From your gamesYour own games
Add a Chess.com or Lichess account and it finds the moments you actually went wrong.
43 levelsMate puzzles
Forced mates on small boards with squares missing. Knights jump the holes, rooks do not.
Every daySpaced review
FSRS keeps the pile small. What you know comes back rarely, what you miss comes back tomorrow.
White to play, mate in one
Pick the white piece, then the square you want it on. Nothing to sign up for.
Most trainers make you replay the whole line. This one does not.
- Step 1
Find the branch points
A fifty-line repertoire is not four hundred moves to memorise. Many of them repeat from line to line. The work is where your opponent has a real choice, and the moves in between follow from those.
- Step 2
Drill only those
The board sits at the fork. Their options cycle past one at a time and you answer each, with the pieces barely moving between them. That is the whole loop.
- Step 3
Keep it with FSRS
What you answer cleanly comes back less often. What you keep missing comes back tomorrow. The due pile stays small enough to actually clear.
Openings for both colours, and growing
Every one shows the position it is trying to reach, which is the part a name never tells you.Scroll sideways.
