Tip from opticians - avoid this if you don't like taking risks (6)
I believe the answer is:
casino
'tip from opticians avoid this if you don't like taking risks' is the definition.
The definition suggests a singular noun which matches the answer.
'tip from opticians avoid this if you don't like' is the wordplay.
I cannot quite see how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is present in the answer.
'like' could be 'as' and 'as' is located in the answer.
The remaining letters 'co' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for casino that I've seen before include "Gaming establishment" , "Las Vegas establishment" , "Gaming place" , "Book by Ian Fleming" , "that offers better risks" .)
