Many thanks to Chandler for today’s Quiptic.

My iPad wouldn’t download The Observer this morning but the usual puzzles were there. As a relatively new solver, I loved Chandler’s Quiptic and didn’t miss the newspaper at all. I might go straight to the crosswords every day.
Thanks PeterO. The one I couldn’t parse was the first def in SHOWER. Guessed it might be British slang, so looked it up, and it was. Unknown to me.
The surfaces for BY DEFAULT, SCOURGE, MARRIAGE and LEATHER made me chuckle.
Sorry, I mean thanks Pierre. Bedtime for me. Glad to see you here before I turn into a pumpkin.
Thanks Chandler and Pierre
I found this easier than his Quick Cryptic yesterday (though that was harder than usual).
This was a fabulous Quiptic, which I managed to solve in a one-er for first time, showing progression.
Liked to use of ‘trouble’; and marriage was certainly an ordeal and ‘a grim era’!
Short but sweet. Nothing to complain about here.
I liked the anagram for MARRIAGE, though MrsTheSheep was less impressed when I read it out to her…
Many nice surfaces, but a special up-tick for BRIDLEWAY.
Thanks Chandler & Pierre.
Enjoyable effort from Chandler. Pierre, you made a slight error in your parsing of SABBATICAL in 26a, the “one” in the clue gives an A not an I.
Why is “cricket side” “on”?
MrsSandgrounder @8
The “on” side is another way of describing the leg side – the side the batsman’s legs are on. The other side is always the off side.
Remember it – it often turns up in puzzles.
muffin@9 thanks for explaining that. I wondered too but, knowing nothing about cricket, couldn’t figure it out.
One or two unparsed until I got here, but I thought this was a really nice puzzle.
Lovely, something not too difficult for once. Thank you Chandler and Pierre.
As a newer solver, I thought that was at just the right level… I had to work at it, but I got all of it and could parse everything except LOUNGER (which is obvious with Pierre’s explanation) and SCOURGE (where I got URGE but struggled with SCO as “Celt”. I now see that it comes from “Scot” or “Scotland” but I’m still not sure the cryptic grammar works.) Thanks Pierre for the very helpful blog!
Comment #14
A nice quiptic. Needed help with a couple of parsings. Thanks Chandler and Pierre!
Nice Quiptic for a newish solver. I too didn’t get “on” for cricket side. My husband (who doesn’t like cryptic crosswords) guessed right and then gave me a lovely demonstration 🤣
