Still all square (4)
I believe the answer is:
I believe this clue is a double definition.
'still' is the first definition.
'all square' is the second definition.
(I've seen this before)
(Other definitions for even that I've seen before include "neck and neck" , "end of the day, reading poetry" , "Level as odds may be" , "Iron - uniform - flat" , "without a rise?" .)
