Brilliant solving (8)

Ross

I believe the answer is:

cracking

This clue is a double definition.

'brilliant' is the first definition.
(cracking can be slang term for amazing)

'solving' is the second definition.
(e.g. cracking a code)

(Other definitions for cracking that I've seen before include "Solving" , "great!" , "Wonderful" , "failing" , "very fast" .)

I've seen this clue in The Telegraph.
