Please ask for umpire's decision (6)
I believe the answer is:
appeal
I believe this clue is a double definition.
'please' is the first definition.
(to appeal to someone is to be pleasing to them)
'ask for umpire's decision' is the second definition.
(as in to appeal to an umpire in cricket)
(Other definitions for appeal that I've seen before include "fetching" , "Supplication to take a higher court" , "Entreat, plead" , "attract one's interest" , "A crustacean" .)
