Goldsmith Defense Picklepuss Defense X Ray Attack in Chess

The Goldsmith Defense Picklepuss Defense X Ray Attack is a tactical motif where a piece (often a rook or bishop) attacks a target through an intervening piece, creating an “x-ray” pressure. In this opening family, the defining feature is that the Picklepuss setup places a piece on a line so that a later move reveals a direct threat on a more valuable enemy unit.
