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

'delivery' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for chinaman that I've seen before include "Oriental - cricket delivery from off to leg from a left-hander to a right-hander" , "special ball" , "Type of cricket delivery" .)

I've seen this clue in The Independent.
