Animal bound to go after some chips (8)
I believe the answer is:
antelope
'animal' is the definition.
(thesaurus)
'bound to go after some chips' is the wordplay.
'bound' becomes 'lope' (to lope is to travel with bounding stride or bound).
'to go after' means one lot of letters go next to another.
'some chips' becomes 'ante' (both can refer to one's stake in casino games).
'lope' put after 'ante' is 'ANTELOPE'.
(Other definitions for antelope that I've seen before include "Eg, gazelle or gnu" , "Reebok perhaps" , "Springbok or gnu?" , "grazing animal" , "it runs very quickly" .)
