King Charlie in bind (4)
I believe the answer is:
knit
'bind' is the definition.
(I've seen this in another clue)
'king charlie' is the wordplay.
'king' becomes 'K' (chess abbreviation).
'charlie' becomes 'nit' (I am not sure about this - if you are sure you should believe this answer much more).
'k'+'nit'='KNIT'
'in' is the link.
Can you help me to learn more?
(Other definitions for knit that I've seen before include "Arrears" , "Unite; use needles" , "Furrow" , "(Of broken bone) unite" , "Link closely together" .)
