I'm working through Polgar's Chess: 5334 Problems, Combinations, and Games and have become a little obsessed with mating paterns/tactics and have started spotting them much easier.  This isn't technically a puzzle since it comes from one of my games, but thanks to this book I saw it was mate in 3.  There is a very tempting move, besides the mate, which is why I thought I'd share it.  White actually resigned after playing their second move, but I don't know if it was because they saw the mate or the other move.  I'm curious about that.

Fine checkmate.  Well done!

I would, were this my game, have played QxQ, and won on material. I tend to be bad at spotting these things.

FLIP THE BOARD!!!

Why?  I always present my games with my side on the bottom, which I think is common practice.

Common practice is white at the bottom

Honestly, who cares which side is at the bottom? Just let the poster go by their preference!

Everybody who reads chess books cares, that is why there is a universal convention. Look at this position, white to play and mate in 3:

But, if Black was at the bottom, a totally different solution. That's why you cant use the top diagram for the bottom position

Well, too bad.  It has a grid, and if you can't see that a8 is listed in the bottom right hand corner, it isn't my problem.  On top of that, I've seen many puzzles with black to move with the 8th rank on the bottom.

Wouldn't 2. ... Qh2+ also have worked?

That makes sense, thanks.

Well, it doesn't since it's only the second move :-p  I think this is what you mean:

If you meant 2... Qxh2+ followed by moving the pawn, then it doesn't.

I think the pressence of the grid should remove all confusion.
