Two objectives:
a) Get control over the knight (it must not be allowed to capture the pawn)
b) promotion

Without checking other possibilities I prefer

1. Kc5 Nc7 2. Kd6 Ne8+

because it's totally forcing for black (everything else loses the knight because of the Kc6 trap).

I think 3.Ke7 is the only move that keeps the pressure and forces 3... Ng7 (...Nc7 4.Kf7 traps the black king in the corner, mate to follow).

Up to this point it took me less than 5 minutes. Now it get's quite complicated. Kf7, g6 and stuff like that didn't work out for me.

Then I was just curious about what would happen when my bishop quits the artillery and joins the infantry with

4.Bg6 Kg8 5.Bf6

Now we trapped the knight and the black king has no other choice than to wander between h8 and h7.

Now we move our king to g4, advance the g pawn and now black is in zugzwang and must give up the knight. The rest is daily routine. Very nice puzzle!
