Catch separate bridge players turning over (6)
I believe the answer is:
entrap
'catch' is the definition.
(entrapping is a kind of catching)
'separate bridge players turning over' is the wordplay.
'separate' becomes 'part' ('part' can be a synonym of 'separate').
'bridge players' becomes 'ne'.
'turning over' shows that the letters should be reversed in order.
'part'+'ne'='partne'
'partne' in reverse letter order is 'ENTRAP'.
(Other definitions for entrap that I've seen before include "Catch in a snare" , "Lure into danger" , "Something to do with gin" , "decoy" , "Ensnare, catch" .)
