Cool one because no matter which side the black king tries to go the same process will lead to the checkmate.

Enjoyable...........

This, for me, was easier than yesterday's.  What made the first move obvious, (this being a puzzle, so I knew there would be a solution) was the immanence of a strong attack by Black's Queen with options the check with ...Qe3+, ...Qe4+, ... Qd2+, or ...Qxf4+.

In a game, I probably would have played defensively, 1. Qxc3, but in a puzzle, I looked hard at what the Queen Sacrifice would do, and I saw tons of opportunities (though not all the way to the checkmate).

Nice Puzzle.

Done in one shot!!!

nicely planned mate by white...

good one

I miss the first move, but after that it was pretty straight forward .

 Don't you just hate having to sacrifice the queen. What a waste. 

nice push
