What is a pin?
A pin freezes an enemy piece on a line because moving it would expose a more valuable piece behind it. An absolute pin, against the king, makes moving the pinned piece illegal; a relative pin merely makes it losing.
How to spot it
Trace every bishop, rook and queen line through enemy pieces toward the king or queen. When two enemy units share a line with your long-range piece, a pin is on the board or one move away.
What this set trains
Pin puzzles teach you to pile pressure on an immobilized target and to notice when a defender that looks solid is actually frozen.
