Rugger player showing heart (6)
I believe the answer is:
centre
This could be a double definition.
'rugger player' is the first definition.
'centre' can be an answer for 'player' (I've seen this before). I'm not sure about the 'rugger' bit.
'heart' is the second definition.
(I know that heart can be written as centre)
'showing' is the link.
Can you help me to learn more?
(Other definitions for centre that I've seen before include "Exact middle point" , "and this may follow 26, 25 [LEFT RIGHT]" , "See 24" , "Player" , "Point equidistant from all other points" .)
