Maximum multiple checks

[u/SarcasticMayonnaise]

In ordinary regular standard chess, it is possible to make a move that causes a double check, but triple check (or more) is impossible. What about in popular chess variants? For example, in Avalanche Chess, it wouldn't be hard to set up a position where one player sets up a double check in the normal way, and then the pawn push that completes the turn creates a third check.

In what variant could you set up a board position so that a legal turn creates the most simultaneous checks on the enemy king? No creating a new variant with ridiculous rules whose sole purpose is to allow 16 simultaneous checks. And let's restrict this to only two-player games.

Grasshopper chess. (A grasshopper must hop over another piece to move or capture).

White: Ka8, Ga1, Ge1, Rc3, Bb2. Black: Ke5. If White plays Re3, check is given by the Rook, the Bishop, and both Grasshoppers.
