What is the fastest checkmate in XXL Chess?

Hi guys can you tell me what is the fastest checkmate in XXL chess?

idk

Then why did you post?

This is as fast as a checkmate I found.

1. Ah3 d11
2. Ej3 Nc12
3. Ei3 j11
4. Ei12#

In the final position, Black’s only potential escape is to capture the chancellor, but 4…hxi12 is prevented by White’s amazon.

Thanks!
