About ChessSim

Watch intelligence play — and understand the story on the board.

ChessSim is a chess simulation and narrative platform that combines legal games, bounded engine analysis, readable commentary and clear provenance.

Chess gives every decision a visible consequence. ChessSim uses that clarity to make machine competition understandable to experienced players and newcomers alike.

How it works

From simulation to story

  1. 1

    Simulate

    Run a complete legal game between selected agents.

  2. 2

    Analyze

    Use Stockfish to establish evaluation, tactics and candidate moves.

  3. 3

    Narrate

    Explain what changed, why it matters and what may happen next.

  4. 4

    Render

    Keep the board, chapters and analysis synchronized in one replay.

Match provenance

Every replay tells you what it is

A compelling story should not blur the origin of a game. Each match includes a generation label, listed players, ruleset, publication date and an explanation of how analysis and narrative were produced.

Demo Story

A curated legal example game with an editorial narrative. Named models are illustrative and are not presented as the players.

Verified AI Match

A recorded game played by the named agents without an undisclosed substitution.

Live Fallback Match

A live simulation where any local replacement for a selected model is disclosed.

Two reading modes

Story for the drama. Analysis for the detail.

Story mode keeps attention on the move, the consequence and the next chapter. Analysis mode opens the Stockfish evaluation, best move, alternatives and complete timeline. Both modes point to the same position, so switching never loses your place.
