Bishop's Opening Discovered Attack in Chess

In the Bishop's Opening Discovered Attack, White uses the bishop’s line to “open” an attack on a target—often after a tactical move that shifts a piece and reveals the bishop’s power. A defining feature is a discovered attack created by a bishop that suddenly gains a new line, usually toward the king, queen, or an unprotected piece. In practice, this motif often appears after developing the bishop and then using a tempo-gaining move that reveals the bishop’s attack.
