AccelaStudy AI Chess is coming soon as an app for iOS.
A few puzzles at the right moment, your downloaded library offline, and room to go deeper when you have time.

Try a position

A small idea
with a big payoff.

Black’s king is safe from the front and trapped from behind.

Find the move, then reveal it. This board runs on this page and saves nothing. In the app, every move you try is checked against the rules, and the explanation waits until you solve the puzzle or ask for the answer.

A small idea with a big payoff

The back rank.

White to move
White to move: find a back-rank checkmateWhite king on g1 and rook on e1. Black king on g8, with pawns on f7, g7, and h7. The rook can move to e8 to deliver checkmate.abcdefgh87654321

Black’s king has no room behind its pawns. Can the rook use the open file?

How it will teach

A Chess Engine Finds the Move.
AVIAN Teaches You to Find It.

Finding the strongest move and understanding it are different jobs.
AVIAN, the adaptive engine behind every AccelaStudy AI product, will decide what you need next, check what you keep, and change the plan as your evidence grows.

  1. An explanation

    Each idea starts with what it is and why it matters on the board.

  2. A guided example

    A real position, worked move by move, before you try one alone.

  3. Your own attempt

    You find the move. Hints are there when you want one, and using one is recorded as help.

  4. Feedback

    Why the solution works, and what the opponent does after a move that does not.

  5. A later review

    The idea comes back after a delay, in a position you have not seen.

  6. Transfer to your games

    The real test: finding the idea in a complete game, against a real opponent.

Planned. AVIAN’s adaptive plan is being connected to the Chess apps. The development build saves your path and your practice on your device today.

ten learning paths

From Your First Legal Move.
Toward 2,400.

Start at the beginning, or start where you are: a planned placement skips what you can already show.
Each path names a target in Lichess rapid, the first rating pool.

  1. Path 1

    Learn to play

    The board, the pieces, check, checkmate, castling, and how a game ends.

  2. Path 2

    Toward 800

    Board vision, loose pieces, one-move threats, and the first mating patterns.

  3. Path 3

    Toward 1,000

    Forks, pins, skewers, simple combinations, and the first endgames.

  4. Path 4

    Toward 1,200

    Candidate moves, forcing lines, sensible exchanges, and coherent development.

  5. Path 5

    Toward 1,400

    Defense, pawn structures, a first repertoire, and reviewing your games.

  6. Path 6

    Toward 1,600

    Calculation discipline, positional plans, practical endings, and the clock.

  7. Path 7

    Toward 1,800

    Deeper calculation, prophylaxis, imbalances, and endgame technique.

  8. Path 8

    Toward 2,000

    Strategic flexibility, difficult defense, conversion, and precision.

  9. Path 9

    Toward 2,200

    Practical judgment, technical endings, and critical positions.

  10. Path 10

    Toward 2,400

    Your own weaknesses, demanding calculation, and competitive refinement.

Targets are Lichess rapid ratings, not federation titles. The higher paths open only after review by strong players. See the full curriculum

Rating targets

A Target You Can Verify.
Not a Number We Hand You.

Every target names its pool: “1,600 Lichess rapid,” never a bare number.
You reach it with rated play in that pool, recorded by the rating provider, along with the course’s learning requirements.

Learning progress

What you have studied and shown, and the ideas that still need review.

Readiness estimate

AVIAN’s prediction for your target, shown with its uncertainty. Planned, and shown only once the model is calibrated.

Verified rating

The rating your provider records, with its pool and its date. The app never assigns one.

How rating targets work

What you will study

From knowing the rules
to reading the position.

Connected ways to study the game, so a lesson has somewhere to go after the board is put away.

Practice the patterns.

Work on forks, pins, mating nets, and endgames on a board that checks every move. Choose puzzles by theme and rating range, then revisit the ideas that need another look.

Puzzle practice in the development build

The puzzle library

Learn an opening’s purpose.

Understand development, king safety, and the plans behind familiar moves. Opening study is planned with the position at the center, for both colors and every move order.

Opening study planned

Openings as ideas

Follow the turning points.

Study historical games with commentary that explains the choices on the board, and guess the next move before you see it. Review of your own games is planned too.

Game study planned

Learning from games

Start with your first move.

Frequently Asked Questions

Can I use AccelaStudy AI Chess now?
Not yet. It is in development, and the position on this page is a small preview. Public access to the web and iOS apps has not been announced. Join the waitlist and we’ll email you when it opens.
Do I need to be an experienced player?
No. The first path starts with the pieces and the rules, and later paths go all the way toward 2,400. A planned placement lets you skip what you already know.
Will the app give me a rating?
No. A rating comes from your rating provider, in a named pool such as Lichess rapid. The app keeps your learning progress and its readiness estimate separate from any rating, and a puzzle’s difficulty never becomes your playing rating.
Will every puzzle have an AI explanation?
No. Every puzzle keeps its original solution. Explanations grounded in the position on the board are being developed separately, and we are not presenting the full collection as a finished set of lessons.
Where do the puzzles come from?
From the Lichess puzzle database, released under CC0. Lichess is an independent organization; AccelaStudy AI Chess is not affiliated with or endorsed by Lichess. About the source collection
Does this page save my moves?
No. The sample changes only the position shown on this page. It creates no account and saves no practice history. Your browser may remember your light or dark theme preference.
