Here's a nice easy one for you guys.  It's forced in a way that black will be checkmated in 5 moves no matter what.

 

In the end, use the Knight on the "d" file.  I have some other variations but that is the way that black survives the longest.  Black can also take bishop on move 4 but then queen takes.

nice!

Nice combo; easy, but not immediately obvious (at least not to a newbie like me). Thank you for this.

Nice puzzle. I struggled with it for a few minutes.

What about  1.Nb8?  throws a wrench in your game, doesn't it?
