Recovered gambler? (6)
I believe the answer is:
better
I believe this clue is a double definition.
'recovered' is the first definition.
(I've seen this before)
'gambler' is the second definition.
(someone who makes bets is a gambler)
(Other definitions for better that I've seen before include "he will take risks" , "More satisfactory or partly recovered" , "More appropriate; gambler" , "Superior; gambler" , "layer" .)
