Crossword Genius

A match of the greatest interest (4)

Ross

I believe the answer is:

test

'a match' is the definition.
(test match is a kind of match)

'of the greatest interest' is the wordplay.
'of' indicates a hidden word.
'TEST' is hidden within 'greatest interest'.

(Other definitions for test that I've seen before include "Cricket match; try" , "Critical examination or trial of qualities or abilities" , "Trial - international game" , "big game" , "Trial; Hampshire river" .)

I've seen this clue in the Evening Standard.
