It's risky to have a croupier as clumsy as this (10)
I believe the answer is:
precarious
'it's risky' is the definition.
(thesaurus)
'have a croupier as clumsy as this' is the wordplay.
'croupier as' anagrams to 'PRECARIOUS'.
But, I'm unsure how the anagram is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for precarious that I've seen before include "having difficulty remaining upright" , "Highly insecure" , "Not having a steady position" , "Hairy" , "Uncertain; likely to fall" .)
