Rat Defense Balogh Defense X Ray Attack in Chess

The Rat Defense Balogh Defense X Ray Attack is a tactical motif where the Balogh Defense structure enables an x-ray line—typically through a piece on the same file or diagonal—to hit a target behind the first defender. A defining feature is that the “Rat” setup creates a long-range attacker (often a bishop or rook) that can pressure a key piece even when it appears protected. The tactic works because the front piece can be pinned or removed, revealing the real threat behind it.
