Its players may have drive (5)
I believe the answer is:
whist
'have drive' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'its players' is the wordplay.
I cannot really see how this works, but
an anagram of 'its' is 'ist' which is within the answer.
This explanation may well be incorrect...
'may' is the link.
Can you help me to learn more?
(Other definitions for whist that I've seen before include "Demand silence" , "Card game for four" , "18th-century card game, the forerunner of bridge" , "Card game, often played at a "drive"" , "Popular card game, sometimes solo" .)
