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

I believe this is a quadruple definition!!

'you'll see this man initially cornered' is the first definition.
'rook' can be an answer for 'man' (rook is a kind of man). I am not sure about the remainder of the definition.

'in' acts as a link.

'board meeting' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'rip off' is the third definition.
(rooking is a kind of ripping off)

'flier' is the fourth definition.
(rook is a kind of birdanimal)

Can you help me to learn more?

(Other definitions for rook that I've seen before include "Crow-like bird" , "Bird; playing piece" , "journalist Jean" , "Steal - castle" , "Another name for castle in chess" .)
