Element of finality in chess opening (4)

Ross

I believe the answer is:

zinc

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

'element' is the definition.
(zinc is a kind of element)

'finality in chess opening' is the wordplay.
'finality' becomes 'z' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'opening' says to take the initial letters.
The initial letter of 'chess' is 'c'.
'z'+'in'+'c'='ZINC'

'of' acts as a link.

Can you help me to learn more?

(Other definitions for zinc that I've seen before include "Metal alloyed with copper to make brass" , "Metal much used in alloys" , "Sivery-white metal" , "Metal, Zn" , "White metallic element usedin alloys" .)
