Strategic Concept Bridge
The 7th Rank Invasion in Chess
Infiltrating the 7th rank (Rank 7 for White, Rank 2 for Black) with heavy rooks immobilizes the enemy king and devours un-advanced pawns in tactical games.
Concept Guide
Known colloquially as "Pigs on the 7th", doubled rooks on the 7th rank exert overwhelming pressure. They pin the defending king, devour baseline pawns, and frequently force checkmate.
