White to move and mate in 3.

Pick a piece, then its square. Every move is checked against the authored line. Nothing here is saved.
This position and its line are checked by Stockfish.
Too much chess, too little time.
There is a course you stopped at chapter four, and a puzzle app that never says why.
Your own games sit unreviewed, and you keep losing them the same way.
ChessPillar connects your time, your games and one curriculum, and hands you the next step.
One loop, in this order.
Progress is evidence, counted in 6 separate kinds. A skill counts as mastered only when it still holds weeks later.

ChessPillar is a personal chess improvement and preparation workspace for ambitious adult players. It chooses your next step, teaches one idea, has you prove it on the board, makes you hold it against Stockfish, and brings it back weeks later before you forget it.
It is a plan with a board under it. It is not a puzzle feed, a video library or a chatbot.
