Complicated bachelor when drunk is quite cynical (10)

I believe the answer is:

hardboiled

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

'quite cynical' is the definition.
I can't judge whether this defines the answer.

'complicated bachelor when drunk' is the wordplay.
'complicated' becomes 'hard' (I've seen this before).
'bachelor' becomes 'B' (abbreviation e.g. BA=Bachelor of Arts).
'when drunk' becomes 'oiled' (I've seen this before. I am not sure about the 'when' bit.).
'hard'+'b'+'oiled'='HARDBOILED'

'is' acts as a link.

Can you help me to learn more?

(Another definition for hardboiled that I've seen is " brazen".)

I've seen this clue in The Irish Times.
