When to push in HU?

Hi. I used to play a few poker a few years ago. I remember using tables for HU tournaments on when to push when the blinds-stack ratio is low.
It would tell you for every hand when it was definitely profitable to push from the SB. It looked something like this:
AA - infinite
KK - 987
QQ - 500
J9 - 15
75 - 9
23 - 7 (blind to stack ratio)
Does anyone know where I can find this table?

Thanks

maybe you mean this? HoldemResources.net: HeadsUp Nash Equilibrium

Or SAGE (google it if you don't know what it is).

Are you thinking of SNGEGT?

I think those are the Sklansky-Chubukov rankings and they can be found here:
