Close both jaws at once: every enemy piece except a king caught directly between two of your pieces (left and right, above and below, or across a diagonal) is pinned and frozen for 2 of their turns.
You draft Pincer Movement in Buff mode. Instant: it takes effect the moment you draft it.
As a tempo card, it buys time: an extra move, a skip, or a freeze.
“Close both jaws at the same time.”
