Making strokes with new cue, most important pool accessory? (8,7)
I believe the answer is:
swimming costume
'important pool accessory?' is the definition.
(a swimming costume might be worn by a pool)
'making strokes with new cue most' is the wordplay.
'making strokes' becomes 'swimming' (as in a swimming stroke).
'with' is a charade indicator (letters next to each other).
'new' indicates an anagram.
'cue'+'most'='cuemost'
'cuemost' with letters rearranged gives 'costume'.
'swimming'+'costume'='SWIMMING-COSTUME'
(Other definitions for swimming costume that I've seen before include "bathers" , "going on in baths?" , "skimpy garment" , "Item of beachwear" .)
