Thanks Teacow, but may I suggest a different solution to 3D? SOBS could be an Americanism which is a short form of “Sons Of B….S” – think female dogs.
I solved 22D despite never having experienced one.
Very enjoyable and not overly difficult. Clever wordplay throughout.
I don’t think I’ve come access IO for satellite before and couldn’t parse SOBS but the rest slotted in nicely.
I particularly liked CHESTNUT and HECKLER.
Thanks STEERPIKE and Teacow.
I parsed SOBS as Peter @1, although I wasn’t aware it was an Americanism.
I think I agree with Peter@1 re the parsing of 3d. I had SOBS for silly old buggers, but couldn’t understand why American. Peter’s take on it works better.
Thanks Steerpike and Teacow.
Crossed with Hovis
Thanks Peter@1 & others. I agree with your parsing of SOBS. I’ll update properly after the England match!
My first go with the FT crossword app which is pretty good except (a) it doesn’t have a timer (unless I missed it) and (b) it’s only free for 30 days, so it will be back to pen and paper then.
Some good words here – SHAMBOLIC (even if I think of it as being hopeless and disorganised more than ‘confused’), RAGAMUFFIN and NINCOMPOOP. Any reference to recent UK political events I wonder?
Thanks to Steerpike and Teacow
Thanks Steerpike for an excellent crossword. I surprisingly found this more of a challenge than Leonidas on Saturday. I used the app to check RESIDE which I couldn’t parse and to reveal ORGIES which I could neither guess nor parse. Otherwise everything else fell into place with CHESTNUT, SHAMBOLIC, IDAHO, STEEPLES, SLUR, and SOBS as favourites. (The American actor, Jack Nicholson, once said that his mother never saw the irony when she called him an SOB.) Thanks Teacow for the blog.
Thanks for the blog, a really neat set of clues. IO is probably the most interesting moon in the solar system , very active with a high concentration of volcanoes. Voyager 1 was first to detect volcanic plumes.
Many thanks to Teacow for the blog and his generous review. Thanks to everyone else for their comments. 3 down was intended as Peter@1 parsed it. Although the abbreviation is not in Chambers, it does appear in Collins and Cambridge (which both list it as chiefly/mainly North American usage).
Thanks Steerpike and Teacow
Steerpike @ 10 s.o.b. (sic) is in the Chambers app, with no indication of being an Americanism.
Thanks Steerpike and Teacow
Further to Simon S@11, s.o.b. is also in the paper Chambers 2014, between sob and soba, not at the beginning of the S section, where one might reasonably expect to find it.
