Locust The Locust is a curious animal, which can only move by eating!
It plays like a
Grasshopper but swallows the sautoir, necessarily of the opposite colour.
It is a Bishop-Grasshopper on c5 and a Bishop-Locust on g1.

Argentine chess a piece plays normally when it captures
but needs a sautoir to play a move that is not a capture (which can go well beyond the square following the sautoir).
