He may make several calls before getting the contract (6,6)
I believe the answer is:
bridge player
'he may make several calls before getting the contract' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot really see how this works, but
'he' could be 'lay' and 'lay' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for bridge player that I've seen is " North, South, East or West?".)
