Definition of "Pawn Cascade"?

I came across this expression in a book, and the author did not explain what it meant.  Can anyone enlighten me?

You mean a pawn storm?

...in a dinky photo.

Speaking for myself but maybe is something like this by exemple? :

Pawn a6 could come from b7 after capture at a6, The pawn a5 could come from c7 after capture at b6 and a5 etc. The picture represented by the pawns could evoke something "à la waterfall" :)

Hm, I think that's more of a Pawn Retaining Wall.

In the diagram, that would be c4-c5-c6 for White and f5-f4-f3 for Black.

Can anyone confirm this?

Never heard that one before (but sounds good to me).

Seems to be a pretty uncommon term. I did a quick google search and came up empty, but now I finally found something that's as close to a proper definition as it gets.

In How to Reassess your Chess (4th ed.), Silman gives the following diagram and says on page 317:

"(...) you need to push the pawn that's next to your lead pawn. In white's case the lead pawn is d5 and the pawn you want to push (...) is the c-pawn. In black's case the lead pawn is on e5 and the pawn next to it is the f-pawn. Thus, both sides will make use of a Pawn Cascade."

My guess is that Silman is the one who coined the term.

That's probably it. I couldn't find it anywhere else.

HappyUngulate,

I think you have my answer.  So it just seems to mean two adjacent pawn chains, and I can see where you might call that a cascade.  Thanks very much.

And thanks to everyone else who contributed too.

I thought "Pawn Cascade" was a song by the early 1980's British New Wave band Leisure Process.  "Here comes our pawn cascade."

I got this book and "What a book". I love it.
