Every tournament has a room for going over the game.

After a round, players carry their scoresheets there, set the position up again and find the move where it turned. Online, the next game starts in seconds and nobody goes back. This is that room, for the games you already played.

Stockfish checks every move
The coach marks the moves that changed the game and says what happened in plain words. In the example above: after 16...Nf4, Qf3 kept the edge. Qd2 left the bishop on c4 without its only defender.

Tomorrow's session is built from them
Today opens with a short plan: a line from the openings you play, puzzles in the motifs you keep missing, one quiet position, and your own mistakes back on the board until they stick.

One coach, in every room

The coach talks you through an opening move by move, stops you when a piece is about to go, and says so when a move was the right one. What it says about your moves comes from the engine’s numbers. What it says about openings and classic games comes from published sources, and the course says which.
