Sounds like a clean pawn structure – the symmetry gives you multiple lines of attack. Treat each corridor as a file and look for a fork of two critical exits, just like a king and rook against a queen. If the center stays open, you can swing a quick flank move to create a discovered attack. Keep the back‑row defended, or you’ll fall into a stalemate trap. In short: keep the symmetry tight, exploit the double threat, and avoid any unnecessary moves that waste tempo.
