The way I took it was as an excuse for a dawdle down memory lane, and flicking through the falling-out pages I re-encountered this old position from Rubinstein - Hromadka (1923), where it's white to play. The killer-move that white unleashed is implied in the text below, so take a little while to try to solve this one before scrolling down:
White to play,
White to play,
. . . which in turn reminded me of something else entirely different. In this position (Young - Kittsley, 1902) from the neighbouring book Chess Middlegames by Laszlo Polgar, it's white to play, and - supposedly - win:
Polgar's solution is 1. Qe4! Qxh5 2. Qxh7+ etc, adding the variations 1...Qxe4 2.Nf7 mate and the more interesting 1...Rdf8 2.Qxg6! hxg6 3.Rd3! gxh5 4.Rh3 +-.
Now assuming that you've solved today's first puzzle, you'll see that the connection between today's two positions is more, of course, than their geoegraphical proximity on my book-shelf. It's that both feature the queen wafting into an attack on herself in empty space, but with devastating effect on the opponent's position. Quite the manouver: so regal, so aloof, so final, so beautiful; something of the feline about it, certainly a motif deserving its own name. Except, alas, in this second position after 1.Qe4, black has a far more satisfactory defence* than those offered by Polgar, after which white is at best equal. Puzzle 2 today is for you to fish that one out.
* maybe not - see the comments.
