Capital, game hearted player? (5)
I believe the answer is:
amman
'capital' is the definition.
(Amman is an example)
'game hearted player?' is the wordplay.
'hearted' means to look at the middle letters.
'player?' becomes 'man'.
The middle of 'game' is 'am'.
'am'+'man'='AMMAN'
(Other definitions for amman that I've seen before include "City of Jordan" , "A capital f-fellow in Jordan?" , "Asian capital" , "Jordan's capital" , "Jordanian capital" .)
