Difficult puzzle

my friend in a group posted this puzzle. I was suprised when i found out the anwser. So i thought I would post this. Move for white

yep but there is another way

my bad the puzzle is wrong i will post the correct one

There's another way

Another way

If you move 1.Qb2, game will be draw by perennial check (1...Bh2+)

Yep King captures then forced draw

There are many ways

another way;) i told you, its hard

I like this line:

1.Rb4 

forces either 1...axb4 (after which qc8 leads to qb7# next move) or 

1...a4 - which result in Qxb8# or Rxb8#

But as an alternative line, what about 1Rf4 ? This forces  1...a4

and prevents the bishop checking on h2.

So the line would be

1Rf4...a4
2Qb2...Bxf4
3Qb7#

To be honest, there are too many solutions to this puzzle to make any one solution work best, unless there is a forced mate in 2 I don't see. 

Hint: 3 move checkmate. First move is by rook

I just gave you a mate in 3, moving rook first.

But there's another way

thisdoesn't work.
