'all square' is the definition.
(I've seen this before)

Can you help me to learn more?

(Other definitions for even that I've seen before include "Deep crisp snow seen on Boxing Day also this" , "Flat, level" , "end of the day, reading poetry" , "Peaceful" , "like the numbers on two sides here" .)

I've seen this clue in The Irish Times.
