What is the name of these pawn formations

I see these a lot.

What are these called?!

idk

This specific pawn structure doesn't have a name. You can name it.

i am dumb

White is completely winning.

Without kings I mean

I asked Google and it said that there is no specific name for it.

Name it the symmetrical pawn structure

The one on the right is the Quart-Grip.

Try Caruana vs L'Ami, Tata Steel, Wijk aan Zee, NL, 2013. Position after move 7.

You must have done so much research ngl

I did find some info, and some page just called it a backward pawn:

Nice find, thanks!

If you watch chess commentary, some broadcasters refer to the formations on the left as “inverted triangles” and the ones on the right as the “bathtub formation.”

I've read (and re-read) Pawn Power by Kmoch, so I knew what the formation was called... it was just a matter of finding some on-line reference to document it.

You could name it the "holey moley" formation, since each side gets a strong hole and a weak hole.
