On the main site, we have a feature called the 'PGN viewer' or 'replayer'. How it works is described in this FAQ: How do I add a replayer to my post? and the tag contains many other questions documenting the various capabilities of the replayer. What we lacked was a space to experiment with it, since the replayer was only active on the main site. Now that the company kindly activated the replayer for us on this Meta as well, this Q&A can be used as a sandbox, not unlike the Formatting Sandbox on Meta Stack Exchange.

This is a sandbox, so it's freely editable by anyone (with 100 reputation or more, since it's a Community Wiki). If you have less reputation, you can still post your own answer. However, it can also be used as some kind of reference for other sites in the network (e.g. Puzzling Stack Exchange) when they need to demonstrate a chess game. This usually happens nowadays through links to other websites, but this looks like a decent spot. It's recommended to link back to the Stack Exchange post where you use it, to make sure somebody here doesn't change the game by accident. And as always, posts should never depend completely on external links, so the position/game itself must be in the post itself as well.
