Fine.. Nice move

Real nice.

I'm not very good at puzzles (or at chess in general, I guess), but this was really easy, as are all puzzles where the opponent (black) can mate in one, narrowing down a lot what one has to look for as the moves must be forced.  
As for the whole "first" fixation you guys have, it only makes sense for those who are on the right timezone - all the rest of us have to sleep and work. 

"how do I sacrifice the queen this time?"

Straightforward.

bill said it exactly right

I love a heafty sacrifice!

first

Awesome puzzle....but....ANOTHER sacfrifice?

Got it!

The Queen bites the dust again.

Sweet! For once the Queen sac made sense and I got it right!

Nice ;-)

Pretty easy but fun! ^^

facil

good puzzle

A bit underwhelming. As others already mentioned: Once you see that you're facing a threat of mate in one, it's gotta be check, check, check, mate. Black not even had options on moves 2 and 3.
