Poker is ripe for duplicitous comments (7)
I believe the answer is:
porkies
'duplicitous comments' is the definition.
(rhyming slang for lies - porky pies)
'poker is ripe' is the wordplay.
'ripe' is an anagram indicator.
'poker'+'is'='pokeris'
'pokeris' anagrammed gives 'PORKIES'.
'for' is the link.
(Other definitions for porkies that I've seen before include "Lies (informal)" , "Lies (colloq.)" .)
