CBB's Forcing Puzzles

I'm going to post puzzles here whenever I see one that's all just 1 forced line.

You don't have to give me the entire sequence. Just tell me the key move in the line so I know you got it right.

This one is white to move.

nooo give the key move, not the first move

i'd accept move 4, 5 or 6 as the key move

edit: oh the comment got deleted and now i look dumb

You NEVER look dumb. I realized that wasn't a one move to checkmate. Just woke up, sorry!

oh i wouldnt post a 1 move checkmate. i'm too mean for that

also ig a couple moves arent technically forcing but it basically is

I thought it seemed far too easy. I figured you were tired or something. I thought it was cute of you. Now I know better - that you were actually being mean!

Qg6

Yeah, that's what I had put. That's not it because escape Kh8.

It is it!

You just need to calculate the follow up

It's a hard puzzle sorry

OK

The answers Nxe6

I don't think people are understanding what key move means

So in this puzzle the full answer is Qg6 Kh8 Qxh6 Nxh7 Ng6 Kg8 Qxh7 Kxh7 Nxf8 Kg7 Nxe6

But that's a bit long to say so instead you just say Nxe6
