A hand-built neural chess engine that thinks in your browser tab. No accounts, no downloads, no waiting. Open the board and it's already calculating your demise.
Under the hood
The same engine that powers the site is a standalone UCI engine: plug it into any chess GUI you like.
The engine has been warming up this whole time. It's seen the Opera Game loop about forty times by now, and frankly, it's bored.
Three ways to face the engine. The difference is how much mercy the undo button shows you.
