Kind of bishop to leave bin out (2,1,3)
I believe the answer is:
in a way
'kind of' is the definition.
('in a way' can mean 'kind of' or 'sort of')
'bishop to leave bin out' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'to leave' suggests deleting specific letters.
'out' becomes 'away' (similar in meaning).
'bin' with 'b' taken away is 'in'.
'in'+'away'='IN A WAY'
(Other definitions for in a way that I've seen before include "To a certain extent" , "as one might see it" , "from one point of view" , "Kind of" , "In some respects, to a limited extent" .)
