Trade And Skewer Chess Puzzles

Trade and skewer is a tactical motif where you first exchange pieces to clear a line, then use the newly opened file, rank, or diagonal to skewer a more valuable piece behind a less valuable one. The trade is not the goal by itself; it is the move that removes the blocker and makes the skewer possible. For example, a capture on a defended piece may expose the king, queen, or rook to a bishop, rook, or queen skewer.
