Who it is for
A chess player who wants to play and ask questions about the position in the same place.

Chess play with move suggestions and feedback
Overview
Accelerator Chess plays out a game of chess turn by turn in a ChatGPT conversation, with a widget showing the board. Alongside making moves, the same thread can be used to request a suggestion or feedback on what was just played.
Positions can be arranged before play starts. The record gives two examples: setting up a fool's mate with the human side taking black, and asking the board widget to display the moment the Immortal Game turned. That makes the app usable for examining single positions as well as for full games. Spheric Admin Ltd is the listed developer, and the record says nothing about engine strength settings or stored game history.

Historic positions can be loaded into the board, so the widget doubles as an illustration tool.
Availability
Accelerator Chess is listed in the ChatGPT apps directory only. Spheric Admin Ltd has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
