Set up any position.
Play it out.
Place the pieces, paste a FEN, or pick an endgame from our library — then play it against Noctie, which defends like a human at your level.
Any position you can imagine
Drag pieces onto the board, or paste a FEN from a book, a course, or last night's lost game. If the position is legal, Noctie will play it with you.
Endgames you can finally use
The library covers theory worth knowing: the Lucena position, the opposition, king-and-pawn wins and draws. Playing them against real resistance is what makes them stick.
Resistance that feels human
Noctie defends and counterattacks like a person, at any difficulty you choose. No engine-perfect defense, no scripted blunders — just the game you'd get from a patient friend who never tires of one more try.
No rank, no clock, no pressure
Custom games never touch your rank. Pick a time control or play without one, choose your side, and replay the position until it feels easy.
Build your own drill list
Name a position and save it: the endgame you lost on Tuesday, the structure your opening always leads to. Your scenarios sit next to Noctie's library, ready to replay.
One position played three times teaches more than three games skimmed once.
