read moreI enjoy puzzles that play with shapes of letters. This one uses two Vs squeezed into a single square in the horizontal direction, but which get interpreted as a W in the vertical. Sometimes these letter squishing puzzles don't work well because people write letters in all sorts of ways — uppercase / lowercase, shorthand, etc. — but this is just about perfect, as V and W don't have a lot of variation.

I really liked HIV VACCINE, a modern, fresh, upbeat entry. TECH SAVVY is also nice, although I've seen it before in crosswords, in one with the same conceit. That one included DIVVIED UP, which to me is a more colorful answer than REVVING UP.
I also enjoyed FLIVVER, a new term to me (old slang for a junker or rustbucket), but I would have really liked all the themers to be long — themers of six letters tend to get lost in the shuffle. CIVVIES could have been lengthened to IN CIVVIES, perhaps?
A construction like this might seem tough, but you can just put a W in those special squares and build the grid like normal. So although I did like some of the bonus fill Ed worked in, like Donne's THE FLEA, A PRIORI, ID SAY SO, it would have been nice to get more. Still, the grid is pretty clean aside from a few minor ATL, ALAI, KAN bits, plus he worked in the apt revealer — VWS — in a perfect location.
A few clues I had to think about:
- WBA = World Boxing Association, so it contains "ring masters."
- A DECK of cards holds 5,148 flushes? The math goes like this: 13 choose 5 (unique combinations of 5 cards out of 13) = 1287, times 4 for the four suits = 5,148.
- How could an inanimate SLED be inclined to provide entertainment for kids? When (physically) inclined down a hill! Nice wordplay.
So although I've seen several puzzles of this ilk (UU = W, D over D = B, VV = W, etc.), I thought this one was generally well-made and enjoyable.
