Indian Defense Budapest Defense Discovered Check in Chess

In the Indian Defense (Budapest Defense), a “discovered check” happens when one piece moves away to reveal an attack on the enemy king, often while the opponent is already under pressure from the Budapest structure. A defining feature is the tactical alignment around the c-file and diagonal lines created by the Budapest setup, where a quiet move uncovers a check from a rook, bishop, or queen. For intermediate players, the key is understanding that the “check” is not the moved piece—it’s the piece revealed after the move.
