The principal stumbling blocks I encountered were concentrated in the northwest, starting with the very uninformative and uninspiring "___ place" (ONES) - is that an example of CLASSISM? - and closely followed by NCAAFINAL (apparently not 'finalfour', which fit count-wise, if not clue-wise) and the phrase "ONHIRE" which I've never heard before (I had ONcall in there for a time) - not to mention "Ancestral spirit in Pueblo mythology" (KACHINA). The clues "Neighbor of Senegal" (GUINEABISSAU), "Abrogate" for UNDO, and the clever and (slightly risqué :) "French open activity, for short?" (PDA) in the next section didn't help matters.
While the above played MAJORROLES in generating ERRORMESSAGEs during the solve, there were, of course, some fine C/APs that ISLES single out here:
"A good word for giving?" (UNCLE) - ha!
"Go to the next line, perhaps" (PRESSENTER) - tricky
"Street wear?" (RUT) - heh
And my favorite, "Was, at one time" (USEDTOBE)
I also enjoyed (in a way) the quote from Hume that AVARICE is "the spur of industry." JETSETTERS, PASTRAMI, CRYONIC, and BENTOBOX are fine fill. And nobody doesn't like SARALEE. :)
I didn't really feel the aptness of "Quick-tempered sorts" for SPITFIRES, so I looked it up on the World Wide Web. I was surprised to find the definitions given were almost identical to the puzzle clue, but I did feel somewhat vindicated by the Merriam Webster page which included examples of the word in use automatically pulled (rather than chosen) from other web pages where the connotation was more along the lines of energetic and feisty than quick-tempered. Also, I had no idea this word was especially associated with females. Learn something new every day. Which reminds me, why is "Leading position" VAN at 42A?
Anyhoo, as I think we agree, all's fair in Friday and Saturday puzzles, so I'm not complaining, but this was another toughie in a string of recent Friday & Saturday toughies for this solver. I didn't finish last Saturday's puzzle until Thursday. :( My performance in recent week-end puzzle has exposed so many GAPS in my knowledge. It does not bode well for the upcoming ACPT.
On the upside for you, dear Readers, I pass the review torch to a better qualified and speedier solver - and possibly earlier-poster - tomorrow. SIA next time.
