An easy one today:

White to move

Sorry if I sound like a daily puzzle poster, but:

rather easy (compared to the last ones), but still beautiful and instructive!

Sorry if you found it too easy. At least you made it to page 1! You could even say first!

And I don't think it's too easy.

I solved it, it must be easy

ZM, since I struggled to solve your previous ones it was great to see a nice puzzle with a solution I saw at first sight.
