**Wasabi Chess** is a web-based chess engine, written in AssemblyScript that runs directly in the Browser.

> [**Play here!**](https://mhonert.github.io/chess)

The React web application embeds the engine using [Web Workers](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API)

to compute the AI moves in the background without blocking the main thread for the UI.
