New · a chess board for your PC

CST-GUI

A clean 2D & 3D chess program for Windows that lets you play Chess System Tal — or any UCI engine — across the board. Play on the flat board or flip into a real-time 3D board. Drag the pieces and watch it think: live analysis with principal-variation lines, a best-move arrow, clocks and every time control from bullet to classical. Take back, swap sides, turn on pondering, load a Polyglot opening book, read and write PGN and EPD. The download bundles four Chess System Tal engines and plays the moment you unzip it — no setup.
