A fun solve as ever, with a good challenge but nothing too scary.
As usual my first pass at through the clues yielded little; after a bit more staring I got a good few in. It took a couple of sittings for me to complete, with PLUTO and COPYCAT being the last to fall, I think.
Thanks as alway to Cyclops for the puzzle.

My last one in was 24A OUTDO which I finally put in after getting 21D BOULDER/”Bolder” to confirm the final O – homophones are always my bugbear.
But I did not understand the wordplay thinking ‘In the open air’ just delivered OUT and not seeing how ‘no alternative’ could deliver DO.
I never thought of OUTDOOR.
I would say ‘In the open air’ could be OUTDOORS (I would not say OUTDOOR myself) and ‘no alternative’ instructs removal of any number of ORs.
Thanks for the blog , good set of clues and all the usual suspects .
I have seen XI used quite often but never the full name in a puzzle .
I do say OUTDOor for in the open air , especially outdoor swimming .
I think 18a is EVINCE around DE. The blog is missing an N.
OUTDO and BOULDER were my last two, too – and I initially parsed the former in the same way as beermagnet. Took an eternity before I saw “outdoor”, even though, like Roz, I would use the word for “open air”. I suppose once one has a sort of semi-parse, it’s tricky to drag one’s brain out of that rut…
An enjoyable crossword, from my favourite setter. The rosette goes equally to XI JINPING and PLUTO.
Many thanks simonbyc and Cyclops
Thanks IC@3, I’ve corrected that now.
