Which way are the black pawns going?
(2) Mate in 3 (incredible)
In which case...
1. Ba8 Anything 2. Qb7 Anything 3. Qh1#
The exception being 1. Ba8 Nd6 2. Qb6 Anything 3. Qg1#.
Sorry Aitorus! I saw that Qxc4 didnt achieve a lot due to the pawns, and thought that the only way I could get the mate was by getting the bishop out the way... which worked!
Also, if you move the queen on the first move then black has the opportunity to move the bishop out the way and save himself, which gave me a clue that the first move wasnt a queen move.
