Game plans you’ve eavesdropped on (8)
I believe the answer is:
draughts
'game' is the definition.
(I know that Draughts is a type of boardgames)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for draughts that I've seen before include "Air currents" , "Board game for two" , "Board game with huffing" , "Checkerboard game for two players" , "the Windies are presumably good at?" .)
