Hi Dirk

The SD card I used today was new after last nights failure plus I used a different image maker but it still wouldn't work after unplugging (I managed to undo it finally) and inserting the new image card.

I did however buy a new Pi Zerro WH for this project earlier this week so I tried that. I had to removed the inner pins and bent the outer to 90° and with the new SD card it worked fine👍

An added bonus which I didn't know about was that you can change the ELO rating level when playing against CT800.

Thank you very much for all your hard work, a CT800 chess computer is a excellent addition to my chess computer collection.

Regards
Bryan
