Selfish Indian opener is a contender, surprisingly (13)
I believe the answer is:
inconsiderate
'selfish' is the definition.
('inconsiderate' is associated in meaning with 'selfish')
'indian opener is a contender surprisingly' is the wordplay.
'opener' indicates taking the first letters.
'surprisingly' indicates an anagram.
The first letter of 'indian' is 'i'.
'is'+'a'+'contender'='isacontender'
'isacontender' is an anagram of 'nconsiderate'.
'i'+'nconsiderate'='INCONSIDERATE'
(Other definitions for inconsiderate that I've seen before include "Lacking thought for others" , "showing no regard for others" , "Self-centred" , "uncharitable" , "Without regard for the feelings of others" .)
