Ph4 / Liechtenstein

You can play chess or watch the game of others, participate in the tournament, play a simultaneous game.

Another fairly decent site with a history.
We enter the URL of the site, but if the project described above gives out the saving dates, clicking on which we get to the start page, and then look at the navigation, it is saved.
Then this project will give links to pages with screenshots.
You can immediately select the desired page, if it is.

Each site has its own advantages, we can use both, depending on our task.
