Possible future queen, old man's offspring hugs Edward (6,4)

I believe the answer is:

passed pawn

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

'possible future queen' is the definition.
'passed pawn' can be an answer for 'queen' (I have seen 'Potential queen' mean 'passed pawn' so perhaps 'queen' could also mean 'passed pawn'). I'm not sure about the 'possible future' bit.

'old man's offspring hugs edward' is the wordplay.
'old man's' becomes 'pa's' (both can mean someone's father).
'offspring' becomes 'spawn' (I've seen this before).
'hugs' indicates putting letters inside.
'edward' becomes 'Ed' (short for Edward).
'spawn' placed around 'ed' is 'sedpawn'.
'pas'+'sedpawn'='PASSED PAWN'

Can you help me to learn more?

(Another definition for passed pawn that I've seen is " Potential queen".)

I've seen this clue in The Guardian.
