Leave Bishop and me in the desert (4)
I believe the answer is:
gobi
'desert' is the definition.
(I know that Gobi is a desert)
'leave bishop and me' is the wordplay.
'leave' becomes 'go' (to go is to depart or leave).
'bishop' becomes 'B' (chess abbreviation).
'and' says to put letters next to each other.
'me' becomes 'I'.
'go'+'b'+'i'='GOBI'
'in the' acts as a link.
(Other definitions for gobi that I've seen before include "very dry place" , "Desert in east Asia" , "barren tract" , "Area of sand" , "Asian desert, Chinese name Shamo" .)
