Improve your
chess force.
A training partner that plays at your level, from 800 to 2400, catches blunders the moment you make them, and turns every mistake into tomorrow’s puzzle.
You play.
The coach watches.
Pick an engine opponent from 800 to 2400 and choose how much help you want. Switch modes below to see what changes on the board.

Nudge
“Something is aimed at your king.” You still have to find it.
Point
The key square lights up. Here it is f7, hit by the queen and the bishop.
Reveal
An arrow shows the engine’s move, g6, and a short explanation of why it works.
