How it works
A native Windows chess viewer and analysis board written in C. The full technical description of ChessViz — what it does, what it is made of, and what state it is in.
The premise
Load and step through games from PGN or FEN, move pieces freely, and analyse any position with any UCI-compatible engine — Stockfish, lc0, Komodo or the engine written alongside it.
It is plain C on GDI with no external dependencies: a green and cream board with Unicode pieces, coordinates, last-move and check highlighting, legal-move dots, board flip, drag-and-drop or click-to-move with a promotion picker, and a two-column move list with animated navigation.
What is included
Drives any UCI engine, with MultiPV analysis arrows drawn on the board
PGN and FEN loading with keyboard and click move navigation
Piece slide animation between positions in the move list
Pure C on GDI — no frameworks, no runtime dependencies
How it is built
ChessViz is built on C, Win32, GDI and UCI.
It is maintained in a private repository; its history is not published.
The method behind it
Every project here starts as a written specification, and the specification stays authoritative once code exists. The repository keeps a build plan with live status, an append-only decision log recording where the implementation departed from the plan, and a handoff document describing the true current state — including the parts that are not finished.
That is why a portfolio this wide is not a shallow one, and it is why this page can describe the product without overstating it.
Current state
In development. Under active work right now.
The source is private. What this page claims is checkable against the product itself, not the repository.
