Queens Pawn Game Chigorin Variation X Ray Attack in Chess

In the queens pawn game chigorin variation, Black often develops with an eye on the d4/e5 complex and creates tactical chances around the center. The “x ray attack” motif appears when a long-range piece (typically a bishop or queen) lines up behind a piece on the same file/diagonal, so the pinned/defended target is hit indirectly. In practice, a defining feature is a line where the attacker’s ray passes through an intervening piece to pressure a more valuable square or unit.
