> Play again in the same checkboard

You can indeed get your revenge. When you start a new game, you can change several option. One of them is how the next board is selected. You can either:

- keep the same board - pick one from a curated list - or generate it randomly

By default, it is set on the 3rd option, but you then need to change it to the first one ("Same Board"), like in this video: https://imgur.com/a/sq8TDbx

> Symetric maps (like in Starcraft 2).

That's not possible at the moment, but someone else had the same request, so I'll have a think. I personally prefer boards that are very irregular and therefore asymmetric, but I appreciate it's subjective.

In the mean time, when you select a board the from the curated list, you can see 5 board types: "very irregular", "regular vs irregular", "almost regular", "regular" and "central pivot". This last one will have boards that are fairly symmetrical (but not completely).

> Does the bot run in the server or in my computer?

It runs on your computer. It's all javascript, running in workers. If the game has a decent success, I'd like to take the time to do a rewrite in a different language to get it in wasm, as it could run faster.

> Can it make a ping when it plays

You should hear the sound of the piece being moved, like in this video: https://imgur.com/a/XoWIJZb If you don't, the only reason I can think of is that the game audio has been turned off, via the button at the top right of the screen?

I'm not sure what chess.com does now, but I believe using a audio hint is really useful for exactly the reason you encountered. And it's even more needed when playing multiplayer without a timer, as your opponent could take even longer to play.
