"He who analyses blitz is stupid."

But let it nevert be said I let a chance to be stupid slip by.

I was put onto this position by another site and got hooked- Black to play his 28th move.

Black played 28...Nxd4 and as you can see he went on to lose.

Black has a much better move here. It took me a while to catch it.

No way I would have seen it at that speed unless I was blunder/lucky (playing a very good move not realising how good it was till after I played it.)

Having said that I am slightly annoyed I did not twig it right away because it is a set up - Black to play and win position and I went off sniffing in all the wrong places.

I know why (I 'm always chasing the King.) but something I teach my students was staring at me in the face.

Is there an unprotected piece in the position?
Is there a check in the position.

If the answer to both these questions is 'YES' then can you take advantage of this?

It's a good one and you now have clues.

Yes it has to be a chess teacher's staple and I prefer to collude with you in not ruining the pleasure for future puzzle solvers.

The problem came to me too from another site and I could not solve it immediately.

The inspiration occurred to me in the middle of the night and I shared the solution back with the friend who sent the position to me.

Now its next day and I found the game and saw your great comment.

I too came here to look at the game because I feared the original diagram was wrong.

it was right! Damn!

I even used e7 to flip the board.
I did get it........eventually.

Solving these things is like looking for something you have lost. It's always in the last place you look.

(pretty obvious that, you are not going to look for something once you have found it so it will be the last place you looked.)

I was looking in all the wrong places

I got it from here:
