Overloaded piece

A piece asked to do two defensive jobs at once — remove one and the other collapses.

A piece is overloaded when it is the only defender of two things at the same time — say a knight guarding both a mating square and a hanging rook. Because it can't be in two places, you attack or capture one target and, when the piece is dragged away to deal with it, the second target falls.

Spotting overload is the practical side of deflection and removal-of-the-defender: first ask what each enemy piece is defending, then look for a piece defending more than it can afford to.

Why it matters

Overload is one of the most common winning motifs in real games — most 'how did I miss that?' tactics come down to a defender doing two jobs.

The mistake everyone makes

Trusting a single piece to hold two threats and never re-checking; the moment it's forced to move, both were only ever half-defended.
