English Defense X Ray Attack in Chess

The English Defense X Ray Attack is a tactical motif where a piece (often a bishop or rook) attacks a target indirectly by “seeing through” another piece on the same line. In the English Defense family, it commonly arises after moves that place a long-range piece on an open diagonal or file, enabling pressure on a more valuable piece behind the first blocker. The defining feature is that the first piece blocks the line, but the attacker can exploit it—typically by pinning, forcing a capture, or winning material.
