Various tailors online in Ireland play unopposed? (9)
I believe the answer is:
solitaire
'play unopposed?' is the definition.
I can't judge whether this definition defines the answer.
'various tailors online in ireland' is the wordplay.
I cannot really understand how this works, but
'online' could be 'e' (abbreviation for electronic, e.g. in ecommerce) and 'e' is located in the answer.
'ireland' could be 'ir' (abbreviation for Ireland) and 'ir' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for solitaire that I've seen before include "thrush" , "Bond girl" , "Gem set by itself" , "Diamond; game for one" , "Patience; diamond" .)
