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

A pin restricts a piece because moving it would expose a more valuable piece or the king behind it. An absolute pin involves the king, while a relative pin involves another valuable piece. Pinned pieces can still sometimes move if doing so creates a stronger threat.

How can I win material with a tactical refutation?

Qxd4 Puzzle (Rated 1194): Win Material — Pin

This Sicilian Defense puzzle demonstrates how piece activity can outweigh a temporary material deficit. Black’s queen has ventured deep into White’s position while creating multiple tactical threats, but its placement also makes it vulnerable. White can exploit the pin on the c3 bishop, the exposed kings, and the alignment of the queen and bishop. A forcing check changes the priorities of the position, creating a discovered attack and leaving Black unable to preserve all of the threatened material.
