    In a skewer you attack the more valuable piece, which when it moves exposes the piece behind it to attack.

    In an x-ray you are attacking a piece through an opponents piece.

    e.g.

    Skewer:

    X-Ray

    The bishop is attacked twice - the white queen is performing an x-ray attack through the black queen.

    why Qc5? Qd3 seemed to save the bishop.

    Don't forget the B2 pawn.

    He's talking about the threat of back rank mate, which wasn't really the point. It was intended as a comparison, not a puzzle.

    Sorry, my mistake. I don't know why I saw Qc3 instead of Qd3. Of course, you are right.

    it was well explained in this thread: it's when your piece acts through an opponent's piece. It can be even a defensive tactic:

     

     

     

     

    Funny how in the videos on here most authors keep confusing the "x-ray" with the simple threat of a discovery or a pin.
