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

'recover from a setback?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'chess move' is the wordplay.
I cannot really see how this works, but
'move' could be 'pickup' (pickup is a kind of move) and 'pickup' is found in the answer.
This explanation may well be incorrect...

'to' is the link.
