The session

A session serves ten exercises. Enough for the work to count, short enough to finish — that is the whole point of the block.

Train starts the session on the selected set. At each position it is your move: play it. The application plays the other side, and the solution unfolds.

What the session serves first

The order is not the set’s order, and that is deliberate: the session starts with what is fragile.

1. Exercises that spaced repetition brings back.
2. Those never attempted.
3. The rest.

Running a second block therefore does not mechanically hand you the same ten positions.

Picking a series up where you left it

When you want the set’s own order instead — the first ten yesterday, the next ones today — right-click an exercise and choose Train from here. The session then follows the set’s order from that exercise, rearranging nothing.

The engine stays quiet

During a session there are no arrows, no evaluation, no engine lines: you search on your own. An exercise solved by Stockfish teaches nothing.

What remains to help when a position resists:

• the exercise’s theme, shown above the prompt (fork, pin, mate in 3…) — you search better when you know what you’re looking for;
• a hint, revealed in stages — the piece to move, then its destination square, and as a last resort the whole move, revealed;
• a wrong move reveals nothing: “Missed — keep looking”. Retry freely; the position will come back at the end of the session. The card steps aside with Escape, a right click, or a click on it — the board stays yours. Only a reveal you asked for through the hint requires playing the shown move to continue.

The counter follows your progress: current exercise out of ten, correct moves out of moves seen.

Studying a position, outside a session

The engine’s silence applies to the session, not to study. Double-click an exercise in the list: it opens like any game, with analysis, the engine lines, Preview mode and the explorer.

That is where you understand why the solution is the solution — after searching for it, not before.

Progress

Each exercise lives in a memory box, exactly like the positions of your repertoire (see spaced repetition): a correct move moves it up a box and spaces out its return, a wrong move brings it back to the front.

The set shows this progress continuously — 12/20 and a gauge under its name, turning green once everything is mastered. It is the only figure worth watching: the rest takes care of itself.
