Win, 3+2

Struggling a bit to solve this one. What does "Win, 3+2" mean?

(I can see that immediate promotion to a queen fails to a stalemating tactic, and I doubt promoting to a rook helps, so that leaves moves of the king or bishop, some of which can be logically discounted, in fact all the moves of the White king fail, so the first move is a bishop move, and only one of those works, OK, so it wasn't that hard to solve!)

3 white pieces, 2 Black ones. I'll give you a chance to get it before giving the answer.

I have got it now, by a process of elimination. Should have seen it immediately. I don't think Black's checks starting on h2 make any difference, need to check that.

EDIT: Yes, White's king can get to the right squares (f7-e6-d5-d4) to prevent the Black rook from a final check to win the promoted queen. And no more stalemate tricks, I don't think.

The Lomonosov tablebases confirm that that move wins and is the only winning move.
