Omit odd pieces of poetry alluding to captain (7)
I believe the answer is:
skipper
'to captain' is the definition.
(synonyms)
'omit odd pieces of poetry' is the wordplay.
'omit' becomes 'skip' (skipping is a kind of omiting).
'odd pieces of' means one should take alternating letters.
The alternate letters of 'poetry' are 'per'.
'skip'+'per'='SKIPPER'
'alluding' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for skipper that I've seen before include "who makes short hops" , "One who misses" , "Chap aboard trawler" , "one that's put over the side" , "Captain - one using a rope" .)
