Poet hints about dropping hearts when one wants an ace? (3,5)
I believe the answer is:
set point
'when one wants an ace?' is the definition.
(tennis)
'poet hints about dropping hearts' is the wordplay.
I cannot really see how this works, but
an anagram of 'poet' is 'etpo' which is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for set point that I've seen before include "Crucial tennis moment" , "Close to victory here" , "5-4, 40-30, for example" , "ready to engrave one name into trophy?" , "at a special advantage, perhaps" .)
