If a rook or queen is pinned along a or , or a bishop or queen is pinned along a , the pin is a "partial pin": the pinned piece can still move along its line but cannot leave that line. A partially pinned piece can break its own pin by capturing the pinning piece; however, this can still be advantageous to the pinning player, as in the example diagram (the pinning rook is defended, so capturing it with the queen would lose ).
