Chesscanon is a free chess training resource focused on strategic and positional understanding. Its strategy trainer presents positions drawn from classic and modern games and asks players to identify the correct strategic approach — such as which pawn break to pursue, how to improve a piece, or how to handle an imbalance.

Unlike purely tactical trainers, Chesscanon emphasizes the positional concepts that separate intermediate from advanced players: piece coordination, pawn structure understanding, planning, and long-term evaluation. The content draws on canonical games and ideas from chess literature.

The site is free to use. It is a useful complement to tactics training for players who feel their positional understanding is holding them back, typically those in the 1200–1800 range who can calculate short combinations but struggle with longer-term planning.
