Announcing mate was a usual finish in the 19th century in games between humans .

The proper way to do it would be to say : "Mate in 7 !!" . The opponent looks
surprised and slightly annoyed . As he can't understand your sophisticated plans
he answers : " So prove it - if you can !"

So white plays Nxc6+ and smiles :-) .

Finally you will have to fix Tiger ..
