I recently came across this formation at random. I vaguely remember reading about it around a decade ago. I want to know if this is a known play.
[FEN "8/8/8/8/8/2NPPN2/PPPBBPPP/2RQKR2 w - - 0 1"]
Even though pieces are White, I'm not claiming that it's a White/Black only formation. It's just to give you an idea.
I had a chat with a friend. It certainly had a slow play, the b and g are, pawns at risk, and there is no clear indication as to how to move forward once this is achieved. However, for the sake of knowing what it is, it'd be great if you could help.
