Open in relation to king’s programme (4,4)
I believe the answer is:
star trek
'programme' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'open in relation to king's' is the wordplay.
'open' becomes 'start' (I've seen this in another clue).
'in relation to' becomes 're' (regarding).
'king' becomes 'K' (chess abbreviation).
'start'+'re'+'k'='STAR TREK'
Can you help me to learn more?
(Other definitions for star trek that I've seen before include "Kirk, Spock et al on TV" , "Extraterrestrial journey" , "Science fiction series" , "Enterprise?" , "TV series" .)
