how to move pieces
Any Blog Topics?

Sure, I could recommend some, but "how simple" are we talking? How pieces move? Opening principles/chess basics? Loose ideas of certain structures? etc.

Look at my other blogs, and see what you can come up with.
I didn't write, or check any of these resources, but this looks like a lot of hyperlinks worth investigating

As for my own, this one was my first chess.com blog post, so I'll include it here:
