Get cross in game (8,6)
I believe the answer is:
contract bridge
'game' is the definition.
(contract bridge is a kind of game)
'get cross in' is the wordplay.
'get' becomes 'contract' ('contract' can be a synonym of 'get').
'cross in' becomes 'bridge' (I can't explain this - if you can you should give a lot more credence to this answer).
'contract'+'bridge'='CONTRACT BRIDGE'
Can you help me to learn more?
(Other definitions for contract bridge that I've seen before include "that requires two pairs of hands" , "Wherein four deck hands" , "Instruction for nose job, perhaps" , "Card game" , "Quartet play this" .)
