Talent test puzzle

white to play

i guess some of you have seen this before. if you have, dont post any solutions.

and try to solve this on your own...
EDIT: by the way. it took over 2 minutes for Kasparov to solve this.

Is it Black to win? Or should we guess.

In fact, it is probably the main line.
Some nice stalemate cheapos there.

Hmmm... How unfortunate that I know this study. A really marvelous piece...

wow that is simple

just get the pawn down on the right to the bottom and check mate em there...

Well I didn't spot this one at all, though Q+P vs Q+P wouldn't work. Of course writing down the moves and it does.

If
1. b6+ Kb8
2. h4 a5
3. h5 a4
4. h6 a3
5. h7 a2
6. h8=Q a1=Q

Now Qxa1 is stalemate, but rather stupidly I missed Qg8, Qf8 or Qe8. Depending on blacks next move white will soon mate.

7........ Qc1/c3
8. Kd7+ (BTW any specific algebraic symbols for a check like this?)

But instead of 7... c1, can't blacks queen shuttle up and down the a column, keeping a diagonal attack on white's queen while white's queen is on row 8 - with QxQ = stalemate? I think it has to be specifically 7 Qe8

7 Qe8 Qa4
8 Qe5+ Ka8
9 Qh8
Now if black's queen moves to a1, white can take it - crucially with check, if black tries Qf4 white has Qa1 check, followed by mate.
