Vienna Game Discovered Check Intermediate Chess Puzzles

In the Vienna Game, a discovered check happens when one piece moves to open a line for a bishop, rook, or queen that gives check to the enemy king. For an intermediate player, this usually appears after White has developed quickly with Nc3 and Bc4 or Bb5, and a tactical move shifts a blocking piece to reveal a direct attack on the king. The defining feature is that the checking piece was already lined up, but its path was hidden until the move was made.
