Bishop put down as "a bit boring"? (5)
I believe the answer is:
bland
'a bit boring?' is the definition.
'bland' can be an answer for 'boring?' (I've seen this before). I'm not certain of the 'a bit' bit.
'bishop put down' is the wordplay.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'put down' becomes 'land' (synonyms).
'b'+'land'='BLAND'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for bland that I've seen before include "Insipid, vapid" , "Mild; dull" , "Without flavour" , "Insipid; lacklustre" , "Mild and insipid" .)
