Queens Gambit Declined Tartakower Defense X Ray Attack in Chess

In the Queens Gambit Declined Tartakower Defense, the X Ray Attack is a tactical motif where one piece attacks a target “through” another piece along a line (most often a diagonal or file). A defining feature is that Black’s setup in the Tartakower structure allows a long-range piece (commonly the queen, bishop, or rook) to pressure a piece that is temporarily shielding the real target. The tactic often appears after moves that fix the center and open lines for x-ray pressure.
