How do I spot a discovered attack in a chess puzzle?

Nimzo Indian Defense Kingside Attack Puzzle (Rated 1133): Discover Mate — Nimzo-Indian Tactic

The key tactical pattern is that one forcing capture opens a direct line to the king, turning an apparently normal position into a mating net. In classical chess, these short combinations often come from piece activity and king safety, not from material count alone.
