The rules of the chase

The marked piece must capture on every move. Clear all the targets without choosing a route that runs into a dead end.

Every move is a capture

Your white piece moves only by capturing a target knight. Circles mark every legal capture from its current square.

Par equals target count

Every board has at least one complete capture chain, so par equals the number of targets. Another legal branch can run out of captures; use Undo and compare the routes.

Calculate one capture farther

List every marked capture, then reject any move that strands your piece. You are training board geometry and move order, not searching for an engine move.

Demo:Capture both knights.

Levels

Rook, bishop, knight, queen: the piece changes every level while the target count and blockers gradually increase.

Stars count capture attempts: par earns three, par +1 earns two, and par +2 or more earns one. Undo restores the board but keeps the capture attempt.

Three-minute capture gauntlet

Clear one chain after another. Each legal capture earns 10 points and a clear adds 25. Any non-capturing click costs five seconds. Skip or a dead end costs fifteen seconds.

Questions about Piece Chase Trainer

What chess skill does Piece Chase train?

It trains line-scanning and piece geometry. Before every move you must see all legal captures and choose one that leaves a route through the remaining targets.

Why is every move a capture?

Removing quiet moves isolates two things you can check exactly: whether you saw the piece’s full range and whether you chose the right move order.

How is par calculated?

Each board is generated from a complete capture chain. One capture per target is therefore the exact minimum.

Does the trainer save completed levels?

Yes. Completed levels, stars and gauntlet bests stay in local browser storage on this device.
