What is a unpinning in chess?

  • Tactics
  • Forcing
  • Pattern

Unpinning is a tactical concept: the act of breaking a pin by interposing a second piece between the attacker and the target. This allows the piece that was formerly pinned to move. Do not stop at naming the motif; calculate the forcing line that makes it work.

What to look for on the board

  • Checks, captures, and threats.
  • Loose pieces and unsafe kings.
  • A forcing sequence, not just a pattern name.
