'sport with jack' is the definition.
I can't tell whether this defines the answer.

'bishop playing slow' is the wordplay.
'bishop' becomes 'b' (abbreviation for bishop in chess).
'playing' is an anagram indicator.
'slow' is an anagram of 'owls'.
'b'+'owls'='BOWLS'

Can you help me to learn more?

(Other definitions for bowls that I've seen before include "Kitchen pots for storing" , "Game played on green" , "Containers for fruit" , "They're rolled towards jack" , "Throws or rolls a ball" .)
