Pressure to rule nerd out as a raider (9)

I believe the answer is:

plunderer

'a raider' is the definition.
(I know that raider can be written as plunderer)

'pressure to rule nerd out' is the wordplay.
'pressure' becomes 'p' (scientific abbreviation).
'to' means one lot of letters go next to another.
'out' indicates an anagram (out can mean wrong or inaccurate).
'rule'+'nerd'='rulenerd'
'rulenerd' anagrammed gives 'lunderer'.
'p'+'lunderer'='PLUNDERER'

'as' is the link.

(Another definition for plunderer that I've seen is " robber".)

I've seen this clue in The Mirror and The Daily Express.
