Catch partner pocketing grand — it's won with tricks (8,6)
I believe the answer is:
contract bridge
'with tricks' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'catch partner pocketing grand it's won' is the wordplay.
I cannot really see how this works, but
'catch' could be 'contract' (to catch an illness is to contract it) and 'contract' is located in the answer.
'partner' could be 'e' and 'e' is found in the answer.
'grand' could be 'g' (G is short for grand as in a thousand) and 'g' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for contract bridge that I've seen before include "that requires two pairs of hands" , "Quartet play this" , "Instruction for nose job, perhaps" , "Wherein four deck hands" , "Card game" .)
