3dn: I am sure that the definition is meant to be “Kent’s number one”, but it needs a question mark or other indicator of a definition by example. Mentioning Kent helps to point out the cricket reference, and it would still be a definition by example without it, as number two in the batting order is also an opener.
[10ac: The answer here reminds me of the unfortunate line in Stainer’s Crucifixion, where the Tenor has to sing “Here in abasement”. It is practically impossible to sing this so that it definitely sounds like three words not four.]
Recently started doing the FT x-words as well after finishing the Guardian. Well, finishing them as much as I can, on some days when the going is tough.
Was put off by the UI a bit initially, being more used to the Guardian website interface obviously. But the content itself is impeccable and downright enjoyable.
This one from PETO was splendid. Didn’t know this usage of ‘lighter’ (22a) but was fairly clued and got it once most of the crossers were in. LOI were 9a and 3d which fell in almost simultaneously.
Thanks, setter & Teacow!
LOi 3d OPENER – disappointed “Kent’s number one” wasn’t Lois Lane, and it was just the obligatory cricket clue.
[A riddle for 28a REDEEM: What do Doctor Dolittle(1967), Rumpole Of The Bailey(1975,1978-92), and Sir Elton John(1947–) have in common?]
Thanks P⁊T
I generally enjoyed this but missed Opener and Shape. Neither impossible and probably gave up a bit too easily.
Why is Iot “a”?
Thanks
Don’t understand your query Moly. Is it perhaps a misunderstanding of the parsing for IDIOT with DI(ana) inside IOTA (a little) minus the A (briefly)? Apologies if I have misunderstood you.
Thanks Peto for a well-crafted crossword. My top picks were ADVOCATE, ON THE GO, LISTEN IN, OPERATE, and GORGE. NHO LIGHTER being ‘barge’ but it couldn’t be anything else. I didn’t have the patience to parse ABOVE REPROACH so thanks Teacow for the blog.
Please could someone explain why red wine = tent? Thank you
HG @8 Tent is a red spanish wine and often crops up in cryptic crosswords so worth remembering. Spanish for ‘red wine’ is ‘vino tinto’ (rather than vino rojo which you may expect) and ‘tent’ comes from ‘tinto’, or so I’m told.
Thanks for the blog, good set of clues , ADVOCATE was very neat .
Frankie@4, REG Dwight , REGinald “Rex” Harrison , REGinald “Leo” McKern.
Correct! 😉
Didn’t get round to commenting yesterday although we solved the puzzle quite quickly and without help. We did wonder, without checking, if ABOVE REPROACH is American usage; we’re more familiar with ‘beyond reproach’.
And a minor point, we think ‘DI’ for ‘princess’ is getting a bit dated these days; but then, one finds things such as ‘GR’ for ‘king’ (George, the most recent being our present king’s grandfather) so we suppose it’s OK – in Crosswordland anyway.
Belated thanks to Peto and Teacow.
