Negotiator in attempt to gamble? Small point (2-7)
I believe the answer is:
go-between
'negotiator' is the definition.
(I've seen this before)
'attempt to gamble? small point' is the wordplay.
'attempt' becomes 'go' (go is a kind of attempt).
'to gamble?' becomes 'bet' (betting is a kind of gambling).
'small' becomes 'wee' (Scottish term for small).
'point' becomes 'n' (North).
'go'+'bet'+'wee'+'n'='GO-BETWEEN'
'in' is the link.
(Other definitions for go-between that I've seen before include "Runner" , "One who acts as messenger or negotiator" , "Intermediary" .)
