A good overview of Shatranj, ElephantHistorian, and also the names of the pieces. In fact, I didn't know of the chess variant where the Shah (Persian king) and Wazīr (counsellor or advisor) exchange places on one side of the board. Good to learn something new.
You mentioned chess problems or mansūbāt, and not to be too forward you might consider telling the tale of the famous mansūbā involving the Dilārām Problem for your next video. Oh, and please don't give any quarter to the ignorant PC crowd when you do.
Although you may not need it, here is a link that may help with the story and its embellishment.
