Chess settings

Who your sparring partner plays like on your own lines, and how the engine rates your moves. Catalog lines bring their own opponent and need none of this.

Sparring

Choose the level of your sparring partner on your own lines: it plays moves from real Lichess games matching these criteria, so it needs your Lichess account connected. The lines of the catalog are not affected: each one carries a pre-generated book of club players (1600-2000), which is what makes their verdicts instant.

Engine

How it works

Stockfish engine provides computer analysis of any position.

  • Position evaluation: See the computer's assessment of who is better and by how much.
  • Best moves: The engine suggests the strongest continuations in the current position.
  • Depth control: Higher depth means more accurate analysis but takes longer to calculate.
