How often do constructors hope that their work leaves solvers with an empty feeling? I enjoy the occasional "leave some squares blank" puzzle. Two from 2013 stand out, one playing on "Wheel of Fortune," and David Kwong's ingenious puzzle Sid mentioned above. Another from 2015 also won a POW!, but this trope goes back a long ways.
Today's RUN ON EMPTY theme worked well, the consistency of RUN atop (three squares to be left blank) so neat and tidy. I particularly enjoyed LABOR UNIONS above what was before the Big Bang: an empty space. Perfect!
Will Shortz is usually pickier about "hidden words" themes; that the hidden word must span across two words of a phrase — DRUNK DIAL wouldn't be acceptable. Despite DRUNK DIAL's evocative nature, I'd have preferred something like BOBS YOUR UNCLE, MR UNIVERSE, OVER UNDER, etc.
Will has also told me that he shies away from puzzles with squares intentionally left blank, saying that solvers expect to put in something, so it's unsatisfying to leave a square untouched. It's like listening to an unresolved penultimate chord in a piece of music. You feel on edge, unsatisfied, until that last note hits home, and then all is right in the world.
Thankfully, there were so many bonuses in the stellar gridwork to overcome those reservations. Sid's craftsmanship is so strong. See how he leans heavily on down entries for bonus fill, and spaces them apart? AD EXECS to BAD JOKES to WOULD I EVER is a perfect example of great spacing.
I also enjoyed Sid's featuring of GURU NANAK. I hate being forced to learn things when all I'm looking for is entertainment, but GURU is a word, and NANAK looks like Pakistani names I've seen. Although I didn't know this person, that didn't affect my ability to finish the crossword, and I ought to know who founded a religion with 25+ million devout followers.
A huge number of clever wordplay clues. GYM as a place where you might see "squatters" — that's people doing squats. [Gear for the bench] had me thinking about baseball, not a judicial bench and ROBE. Delightful!
Some Thursday crosswords focus on being hard for hardness sake, but I like this type much better. A reasonable trick, a colorful grid, and a slew of headslap-inducing wordplay clues to make the solve crunchier? That's my jam.
