Visualisation Drills
The position you see is several moves behind the puzzle - play the moves in your head, then solve from the imagined position. Adjustable difficulty with optional warm-up ramp.
Forcing Moves
Find all checks, captures, and threats in a position. Builds the habit of scanning for forcing moves before calculating - the most impactful tactical skill.
Blunder Check
Select from candidate moves: which is the blunder and which is the best? Trains defensive awareness and spotting your opponent's threats.
Opening Builder
Import PGN, organize chapters, annotate with AI, and drill lines with spaced repetition. Check soundness automatically - and let Lessons from Games replay the opening lines where you left your prep in real games.
Detailed History
Review every session and puzzle. Track rating progression, accuracy trends, and weak themes. Replay mistakes rebuilds a session from your past wrong puzzles so you drill the patterns you keep missing.
Train on your own games
Connect your Lichess or Chess.com account and KayChess works in the background: From your Games turns your real blunders and missed tactics into puzzles, Lessons from Games replays the opening lines you drifted from, and Scouting finds any player's recurring leaks before you face them.
