AI Game Cards

Chess puzzles & trainers for ChatGPT, Claude & Gemini

Updated

Chess puzzles, endgame drills and an openings coach, every answer written on the card and every puzzle engine-checked. Free, no signup. Each game is a ready-to-play prompt (we call it a game card) that you open in your own AI assistant.

Chess with an AI works when the position and its answer are written on the card before you play. Assistants lose track of a board over many moves, so these are set positions with checked answers: tactics puzzles and an openings coach in Counterplay, and seven textbook endgames in The Resumption.

What do AI assistants get wrong about chess, and what do they get right?

Play a full game against an assistant in an ordinary chat and the board drifts. Captured pieces come back, an illegal move goes through, and by move twenty you are playing two different games. The model is writing plausible chess, and nothing in the chat keeps track of the position.

Counterplay and The Resumption never ask it to. Each of Counterplay's eight puzzles is a fixed position with one winning idea, such as a pin, a skewer or a double attack, and the answer and a one-line reason it works are written on the card; its openings trainer walks three mainlines, the Italian, the Ruy Lopez and the Queen's Gambit, also written out move by move. The Resumption does the same for endgames: seven named positions, Lucena and Philidor among them, with the result of every legal move copied onto the card. The assistant presents the position, takes your move and reads you what the card says about it, which is a job it does well.

Every Counterplay solution was checked against the Stockfish engine and is its best move or a forced mate. The Resumption's positions were checked against the Syzygy endgame tablebases, which are exact for positions this small. Both checks were last re-run on 3 Oct 2026. No engine runs while you play and no answer is hidden from view: the checked answers are printed on the card.

Questions about chess puzzles & trainers

Do I need to know chess notation?

No. Say the move in plain words, such as "rook to b8" or "knight takes the pawn", and the coach translates; standard notation works too. The Resumption also gives each position as a plain list of which piece stands on which square, and as a FEN you can paste into any board viewer.

How long does a session take?

Counterplay's eight puzzles take 15 to 30 minutes, and its openings trainer has no score or clock at all. The Resumption takes 20 to 35 minutes for seven boards. Its ninety-minute clock counts moves, hints and passes, and thinking costs nothing. You can save either card partway through and carry on in a new chat.

What level are the puzzles aimed at?

Counterplay is club-level tactics: pins, skewers, double attacks and back-rank ideas, the patterns that decide most amateur games. The Resumption is standard endgame technique, the rook endings and king-and-pawn rules club players are told to learn, and it closes every board with the method and the reason the natural-looking move fails. Anyone who knows how the pieces move can attempt both.
