Decided against a bid in spades perhaps (6)
I believe the answer is:
passed
'decided against a bid' is the definition.
I can't tell whether this definition defines the answer.
'spades perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'spades' anagrammed gives 'PASSED'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for passed that I've seen before include "Chose not to bid" , "Succeeded" , "Got a good grade" , "Overtook and moved ahead" , "Was successful" .)
