Somehow drew diamonds, holding ace and king (6)
I believe the answer is:
edward
'king' is the definition.
(I've seen this before)
'somehow drew diamonds holding ace' is the wordplay.
'somehow' is an anagram indicator.
'diamonds' becomes 'd' (abbreviation in bridge say).
'holding' means one lot of letters goes inside another.
'ace' becomes 'a'.
'drew'+'d'='drewd'
'drewd' is an anagram of 'edwrd'.
'edwrd' enclosing 'a' is 'EDWARD'.
'and' acts as a link.
(Other definitions for edward that I've seen before include "Lear, perhaps" , "Boy" , "Lear, maybe" , "Mans name" , "Name of eight kings" .)
