9.2
October 16, 2026
What's new in 9.2 • Cleaner practice: no more lines that repeat the one before or just add one move, and section headings are no longer drilled as lines. • Clearer names: mixed sections are split by the move actually played, and lines that shared a name now show the move that sets them apart. • "Main line" label on the most-played line of 29 openings, checked against elite games. • Tap a section to start its first line. • Show line: watch the whole line played on the board, then play it from memory. • New here? Your first line plays itself, so you see how it works before you move. • Watch line after line: double-tap » to skip to the next one. • Choose how fast Show line plays in Settings. • Your progress: a new graph shows your accuracy, blunders and mistakes game by game, with a table view. Signed in, your coached games sync between iPhone and web. • 6,500+ new opening lines from master and elite games, each checked by Stockfish. • The coach no longer gives the answer away: missed moves hide behind "show move" until you tap. • Give your queen away and the coach offers a take-back, even in a lost position. • Report a note: tap the flag on any coach note that looks wrong or unclear. • Computer levels now match Chess.com ratings, and Strong plays much stronger. • Many coach notes corrected after checks against master games. • Smoother premoves and dragging while the computer thinks.
