Play features two bishops in valley (6)
I believe the answer is:
dabble
'play features' is the definition.
'dabble' can be an answer for 'play' (dabbling is a kind of playing). I am unsure of the 'features' bit.
'two bishops in valley' is the wordplay.
'two bishops' can mean two substitutions for 'bishop'.
'bishop' becomes 'B' (chess abbreviation).
'bishop' becomes 'B' (chess abbreviation).
'in' means one lot of letters goes inside another.
'valley' becomes 'dale' (dale is a kind of valley).
'b'+'b'='bb'
'bb' inserted within 'dale' is 'DABBLE'.
Can you help me to learn more?
(Other definitions for dabble that I've seen before include "Wet by splashing or work casually" , "Take dilettante interest (in)" , "Take casual interest (in)" , "Work with in an amateurish manner" , "Study or work at casually, not seriously" .)
