Will have to buy a Chambers. Not common in Canada. My Concise Oxford does mention NOT MUCH CHOP - unsatisfactory (Aus./NZ) & also OU. Didn't dig deep enough.
Got the BIT bit. ;-)
Hello Zardov - It seems to me that Chambers is a must for cryptic crosswords - always the most complete reference. I have a Shorter Oxford - never used, and an older Collins for proper nouns - not in the newer edition, I believe.
Thanks, AJH. I thought I'd covered all forms of "run" but forgot about stockings! I'd even flirted with the snake in the grass dropped from the full answer but I couldn't make it add up...
