Lasker Simul Special Discovered Check in Chess

The “lasker simul special discovered check” is a tactical motif in the Lasker Simul Special family where one move opens a line to deliver a discovered check, often while also creating a second, immediate threat. For intermediate players, the defining feature is that the checking piece’s line is “unblocked” by a move that also changes what your opponent’s pieces are defending. In practice, it’s a double-purpose move: it reveals check and forces the opponent to respond to the check while you gain tempo or win material.
