rake-off

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

'percentage in unlawful venture?' is the definition.
'rake off' can be an answer for 'percentage' (thesaurus). I am unsure of the 'in unlawful venture?' bit.

'playboy out' is the wordplay.
'playboy' becomes 'rake' (old-fashioned term for a womanising man).
'out' becomes 'off' (I've seen this before).
'rake'+'off'='RAKE-OFF'

'for' is the link.

Can you help me to learn more?

(Other definitions for rake-off that I've seen before include "(Illegal) commission" , "Commission from shady deal" , "Criminal's profit" , "Dishonest share" , "(Unfair) share of the profits" .)
