What is something interesting about chess that I could open and close a speech with?

HandsOnCelibacy asked:


I’m doing a demonstrative speech on how to play chess this morning. I need to open my speech with something captivating (the grabber) and close with something–the same thing, something else–suggesting unambiguously the closing of the speech (the leaver).

I plan on opening the speech with Iran’s relationship with chess. I can’t think of a more clever idea. I don’t yet have a leaver.

Any thoughts would be really appreciated.
