Blind pigs is the informal name for two rooks doubled on the seventh rank. They typically create decisive threats against the enemy king and pawns.
The formation earns its name from the way the rooks root around behind the opponent’s pawn shield, picking off pawns that can no longer be defended from the front. Once both rooks reach the seventh, they coordinate extremely well: one rook often ties the enemy king to the back rank while the other harvests pawns or creates mating nets.
The practical strength comes from the rooks’ ability to attack both horizontally along the seventh rank and vertically down the files. Even when material is level, the defending king is frequently confined to a corner or forced into perpetual checks, while the pawns fall in quick succession. Many rook endings that look drawable become lost the moment the second rook joins its colleague on the seventh.
Attacking play
The attacker should keep both rooks on the seventh whenever possible. Moving one rook off the rank to chase a single pawn often allows the defender to trade or activate their own pieces. The rooks protect each other, so the attacker can usually ignore checks that do not force a trade.
Defence
Defending against blind pigs requires urgent counterplay or the willingness to return material to eliminate one of the rooks. Passive defence usually fails because the rooks protect each other and control too many squares. The defender’s best hope is often to create threats against the opponent’s king or remaining pawns before the pigs can consolidate.
