About Calmonbliss

Calmonbliss is the home for a growing collection of services. Chess is one of them, with more planned for the future.

Explore chess

Our chess service brings a chessboard to your browser, with a clear 2D view and a 3D chess set. Play a game, revisit a decision, or mark an idea on the board.

Play at your own pace

Play White against the Stockfish engine, or turn the engine off to move both sides on the same device. There is no chess clock. Take back a move when you want to try a different idea, and use the move list to look through the game.

Two views of the same position

Switch between 2D and 3D without starting over. The 2D board keeps the position easy to scan, while the 3D view offers adjustable camera and lighting settings. On a device with a right mouse button, red square highlights and arrows help you compare candidate moves.

What to expect

No account is needed. This is a local board and computer opponent, with no online matchmaking, ratings, or saved game library. Games and board settings last for the current page session; reloading or closing the page starts fresh.

The engine calculates moves on your device. Switching to 2D can help on devices that struggle with 3D graphics. See How to play for controls and a short practice routine.
