Names a cocktail opening seedy joint with the type of skill one needs if they're taking a punt? (10)

I believe the answer is:

seamanship

I'm a little stuck... Click here to teach me more about this clue!

'the type of skill one needs if they're taking a punt?' is the definition.
The definition suggests an adverb but the answer is not.

'names a cocktail opening seedy joint' is the wordplay.
'cocktail' indicates anagramming the letters.
'opening' indicates taking the first letters.
'joint' becomes 'hip' (part of body).
The first letter of 'seedy' is 's'.
'names'+'a'='namesa'
'namesa' with letters rearranged gives 'seaman'.
'seaman'+'s'+'hip'='SEAMANSHIP'

'with' acts as a link.

Can you help me to learn more?

(Other definitions for seamanship that I've seen before include "Sailing skills" , "Skill of a sailor" .)

I've seen this clue in The Irish Times.
