Check with rook initially exposed expert (6)
I believe the answer is:
rebuff
'check' is the definition.
(I've seen this before)
'rook initially exposed expert' is the wordplay.
'rook' becomes 'r' (abbreviation in chess).
'initially' says to take the initial letters.
'expert' becomes 'buff' (I've seen this before).
The first letter of 'exposed' is 'e'.
'r'+'e'+'buff'='REBUFF'
'with' is the link.
(Other definitions for rebuff that I've seen before include "Reject in an ungrateful manner" , "Turn off" , "Ungracious rejection of a friendly approach" , "Reject bluntly" , "'Slight, snub (6)'" .)
