Evident getting behind, win at cards (9)
I believe the answer is:
overtrump
'evident getting behind win at cards' is the definition.
I can't judge whether this defines the answer.
'evident getting behind' is the wordplay.
'evident' becomes 'overt' (I've seen this before).
'getting' says to put letters next to each other.
'behind' becomes 'rump' (informal term for the buttocks).
'overt'+'rump'='OVERTRUMP'
Can you help me to learn more?
(Other definitions for overtrump that I've seen before include "Excel at trick" , "use a superior club?" , "better" , "Way to take trick" , "Win trick by playing higher card" .)
