Nice idea. BTW, curious how you do this, I suppose start a tournament with Fritz and then stream it on Youtube?

You could use Fritz or any chess GUI or broadcast anything you wish. But I find Cute chess much superior for testing. As you can run many games at the same time depending on the cores used by the engines in testing, and the number of cores on your system. So you can use 100% of your system in testing. This speeds up testing greatly over the Fritz GUI.

Cute chess is a must!. https://cutechess.com/

1. Download a GUI.
2. Download OBS Studio it is FREE. https://obsproject.com/
3. Set up OBS to stream your GUI, and any other windows you want to broadcast on your YouTube Account.
4. Setup your live stream on your Youtube go live page.
5. Hit live stream in OBS studio.

Here is what my OBS studio looks like in action.
