Czech playwright placing Knight on headland (5)
I believe the answer is:
capek
'czech playwright placing' is the definition.
I know nothing about this answer so I can't judge whether this works.
'knight on headland' is the wordplay.
I cannot quite understand how this works, but
'knight' could be 'k' and 'k' is found within the answer.
'headland' could be 'cape' (I've seen this before) and 'cape' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for capek that I've seen before include "Karel --, Czech novelist and dramatist" , "robot inventor" .)
