English Opening Kings English Variation Discovered Check in Chess

In the English Opening’s Kings English Variation, a “discovered check” happens when one piece moves away to reveal a line to the enemy king—often from a rook, bishop, or queen on an open file/diagonal. The defining feature is that the move is both a tempo-gaining reveal and a tactical threat, with the king in check immediately after the “unblocking” move. In this motif, the tactical idea is tightly connected to how the Kings English setup opens lines for your major pieces.
