Nice puzzle :)

The stalemate of the black pieces due to pins is a pleasant theme - as is the simple transfer of the white Queen from one extreme diagonal to the other. Fun to solve and a good lesson in the strength of pins and zugzwang

1 Qa1

This prevents 2 Qa8 allowing Blacks King to take the pawn and freeing his position somewhat! Mate would still be inevitable, but not in three moves.

Brilliant

It was easy to see that the queen can give mate on a1 or a8 if the king takes the knight or the pawn respectively, and to understand that any other first move than a queen or king move would spoil that possibility. But it takes some deeper insight to find that a1 and a8 can also be reached by the queen from h8. Whites king just has to move to the right square to open all lines of the mating net, and then blacks zugzwang forces him to play one of the deadly moves in the end

Actually i was wrong, because all other first moves than a king move (and not queen or king), will spoil the possibility of a mate on a1 or a8. So after all, it is somehow very logical that the first move is a king move (and also that it is Kf7)

mate in 3 moves starts also with 1.Qa1

1. Qa1 c6
2. Qc3 Kxa3
3. Qxb3#

Mate in 3 only after 1.Kf7

There is no other mate in 3.

After 1.Qa1 c6 2.Qc3 black just plays Kxa5 (and of course not Kxa3) and white has no mate

Black can also play 1. ... Kxa5 (instead of c6) and then white also has no mate in 3
