It was really nice of the calendar to start December on a Thursday so I would spin into action at the start of the turn this week. I always look forward to the Friday and Saturday puzzles. Themeless grids often seem the most fun, with the best entries and the cleverest clues.
Today's is no exception. There are a ton of fun answers here, with a lot of colloquial touch. I love 59A: "Fingers crossed!" (HERESHOPING) and 37D: Claims, with "on" (HASDIBS). There's also the excellent PRIZEINSIDE and 10D: Something an athlete puts on (GAMEFACE), no question mark needed.
I broke into the grid, strangely, at 24D: Scottish "John" (IAN) as my first confident answer. I would have gotten that without any assistance, but I also had the ____TIES from the decade answer just before it, and then CIAOS (a strange plural) confirmed the lot. I worked down into the SW corner - I always like APRIORI, and HELIOS is a nice bit from Greek myth.
28D: Front ends? (CEASEFIRES) is a great answer and a really tough clue! I needed a lot of crosses to get that one. 40A: First name in foundations (ESTEE) on the other hand fooled me not at all. There's a bunch of not so great crossing answers in the SE. ACTIII always feels like a desperate move, and HIHO and ANON are pretty neutral. CHATTEL is a great word with not so great connotations in the worlds of race and gender relations.
The C of 36A: Sat in a dugout? (CANOED) was my last square entered. That's a good clue for not such a great answer. I do like OSCARNOD, and 16A: Suffix with lip- (ASE) was unexpected, which is good for such a blah answer.
I'm not so hot on the long answers in the NW corner. EDITORSNOTE isn't all that interesting. 17A: It comes with a dish (SATELLITETV) is better. 1D: Not as much (LESSSO) has that fun run of three S's in a row. But we pay with the peculiar partial ATEN, and classic crosswordese ORLE.
1A: Ceremonial basin (LAVABO) gets a B+ for Latin.
I had fun solving the puzzle, but as I look over it again, I see all the glue needed. Overall, I give it a thumbs up.
