Draw game? He painted frescoes (7)
I believe the answer is:
tiepolo
'he painted frescoes' is the definition.
(I've seen this before)
'draw game?' is the wordplay.
'draw' becomes 'tie' (synonyms).
'game?' becomes 'polo' (polo is a kind of game).
'tie'+'polo'='TIEPOLO'
(Other definitions for tiepolo that I've seen before include "He showed artistry" , "Old master" , "C18 Venetian painter" , "Giovanni Battista ---, rococo painter" , "Italian artist" .)
