Sketch equal match (4)
I believe the answer is:
draw
I believe this clue is a triple definition!
'sketch' is the first definition.
(to sketch is to draw)
'equal' is the second definition.
(drawing is a kind of equaling)
'match' is the third definition.
(I know that draw is a more specific form of match)
(Other definitions for draw that I've seen before include "Attract; sketch" , "Tied score; sketch" , "Design" , "Make representation" , "Snag" .)
