not easy for me

this is a hard but interesting puzzle to solve

Fascinating !  Much to like in this one - so much in it. I thought that there was a redundant move  (5.Rh2) in this but now see it's necessary to unblock the f1 bishop to attack h3.
I thought I saw a different solution but it doesn't work. There are some interesting variations in this one, some of which I've included in this  diagram:-

{ If you're not familiar with these diagrams, just click on the first move of an alternative sequence (the part within the (1.Bc2.. ) ) and you can then step through the moves using the buttons. }

Great puzzle - be good to have some more like this.

Edit: Just noticed I've repeated one line - please use the second of the two.

Medium!

good!

the first move by the black knight just to get killed by queen looks unrealistic...
