I'm the composer of this puzzle.

I thought 1..Kd4 let the king escape, but Ne2 still appears to be mate.  Nice.

think harder!

Yeah, you're right.  It took me a second, haha.  Very nice.

Thanks.

can someone post all possible answers and replies?

Nice one.

1. Qe6+ Qxe6 2. Nf3#

1. Qe6+ dxe6 2. Nxc6#

1. Qe6+ Kd4 2. Ne2#

But how to achieve this board position?

Good, if 1...PxQ then same result but with other Knight

if 1...dxe6 Nf3+ Qxf3.

The first one I think you meant: 1. Qe6+ Kxe6 2. Rxe4#

It's in my post, the second solution!

This is a good way to get to the position with white's move, but, any faster is possible?

Okay, cute.  But world's best? lol  I don't think so.

Here, the most exiting title is the one usually gets more views and comments, SO?

Well, that's great if you want the comments to all be lol's. 

Now, im going to be commenting just so is first on the first page!

y d game is like this?

I asked myself : why this knight is on ' a7 ' and then fast found the solution.

cool
